D12.5 – LISBON CITY REPORT

1. Introduction

This document contains a detail description of the methodology for the scenarios implementation and the model cascade results for the Lisbon City Case. In this way, the objectives of this deliverable are:

• The analysis of the set of scenarios defined in WP10 for Lisbon.

• The evaluation of the scenarios in terms of the indicators of sustainable urban transportation defined in work package WP08.

2. City-case description

2.1 City Location, Urban Structure and Land Use

Lisbon, the westernmost city in continental Europe, is located in 9ºW longitude and 39ºN latitude in the Southwest of Portugal, on the north bank of the Tagus Estuary, on the European Atlantic coast. The city has approximately 600.000 inhabitants. However, accounting with the various satellite towns, the population of Greater Lisbon raises to approximately 2,1 million people, in an area of 1.000 km2. Due to the Atlantic Ocean influence, this region is characterised by complex sea breeze circulations, with a significant impact on the pattern of transport and dispersion of air pollutants. A particular effect on local air quality has also the complex system of hills (Lisbon is known as “the town of the seven hills”) and the flat terrain close to river estuary. Lisbon Metropolitan Area (Figure 1) can be sub-divided in various crowns: crowns A to D represent Lisbon City, crowns A to E account for the Great Lisbon Area, and crowns A to F the Lisbon

Metropolitan Area. The land use in Lisbon can be divided in 5 classes through the ratio jobs/population for each crown: residential areas, mixed areas with residential dominance, mixed areas with jobs dominance, job and dense job areas. Concerning this classification, the Lisbon City Centre (Crowns A and B) is a dense job area, C and D crowns are mixed areas with job dominance, and crowns E and F are residential areas. Therefore the land use patterns show the large travelling needs in Lisbon Metropolitan Area: public transport, which includes buses, taxis, trams, trains, metropolitan and fluvial transport, was responsible for the transportation of about 520 millions of passengers in 1998; every day, the total number of private vehicles in circulation in the city is of about 1 million, considering the 40% that proceed from surrounding areas.

Figure 1. Lisbon Metropolitan Area (division by crowns).

In the last years an unprecedented road-building process has been under way in Portugal: from 1990 to 1994, the total length of motorway increased in about 84%. This trend is expected to continue and emissions from the transport sector are predicted to increase 46% between 1990 and 2000 and 78% by 2010. Actually, traffic emission of NOx and CO represent about 97% and 92% respectively of total anthropogenic emissions in Lisbon municipality. The impact of road traffic on Lisbon air quality at regional scale was analysed on previous works confirming the importance of the development and application of an efficient air pollution abatement strategy in this area.

The resident population of Lisbon do every day 1,9 trips. From these, 1,4 trips are motorised and 0,5 by foot. The number of trips realized daily by the resident population of the metropolitan area of Lisbon is about 4,86 millions: 1,17 million are made on foot, 2,1 million in private transports, 1,3 million in public transports, 0,08 million in a combination of private and public transports and 0,18 million in another mean of transport.

For VISUM, information about public and private transports is need, as well as an OD Matrix, for each transport system:

- Private transport

• Category and capacity of roads

• Maximum velocity allowed

• Connection to the public transports network

The fundamental roads include arterial and principal ways. These guarantee the travelling connections of the arterial way to the diverse urban sectors and integrate the main avenues and urban roads. The main routes establish the connections between the city sectors. The secondary way has the role of distributing and collecting the traffic from the local to the fundamental network. The local network assures predominantly the local access to the urban functions and activities, which include streets with distinct utility and that mix vehicles and pedestrians.

In the Lisbon network there are 5 link types. Each one has a unique set of private transport capacity and maximum velocity allowed:

Type Cap-Prt V0-Prt 12 78 750 110 22 50 000 100 32 12 250 80 65 16 000 50 67 7 875 30

- Public transport

The public transport consists on 50 lines of Buses (26), Trains (10), Trams (5), Subway (4) and Boats (5).

The input information for the network related to the public transports was:

• All public transports networks, their timetables and stops

• Connection between the different network

- OD Matrix

The OD Matrix is calculated taking into account the different motives (work, school, health, leisure, visit relatives, etc.) that lead people to dislocate them selves, daily, form one zone to another. For Lisbon city case exists 3 daily OD matrixes (public, private and good vehicles). It can be seen in figure 9 the public transport OD matrix for the baseline scenario, through the MUULI tool.

Figure 9. OD Matrix for Lisbon City Case.

3.1.3 Result analysis

VISUM gives the flux of vehicles, for private transports and passengers, for public transports, as shown in Figures 10 and 11.

Where, B=Bus, S=Subway, P=Car, L=Heavy vehicles, T=Tram, Z=Train and N=Boat. The results of VISUM for private transport were tested against measured data from traffic counters located in strategic roads sections. Direct comparison between simulations and measures together with elaboration of statistics, (VISUM has a proper module for that) indicates that the model, reasonably, represents the real Lisbon situation for what concerns private traffic.

Comparing the public transport results with the values of literature (no information is available for public counters in Lisbon) it can be seen that there is a good concordance if we look for the Passenger-Km indicator, but not for the vehicle-km. For example, for Bus, there is a difference of 7,1% in Passenger-km and a difference of 73,3% in Vehicle-km.

3.2. TREM

3.2.1 Domain Definition

TREM model has been applied to the Lisbon Metropolitan Area (AML). A definition of the study area is based on availability of traffic volume data required for emission estimation, and for this reason the TREM application is coincide with the domain selected for VISUM transportation model.

3.2.2 Input Data Description

The main inputs required by TREM are: - Traffic volume; - Vehicle speed; - Fleet composition.

- Traffic volume Traffic volumes for the study domain with link resolution are provided by VISUM. Before using for the emission quantification, the data were checked against the traffic counts and statistical indicators. For this purpose, several measurements point located within the urban area were selected. The mean daily traffic volume measured during two consecutive weeks of May 2000 was compared with VISUM outputs. An overall, the modelling results underestimate traffic volume on 28%. This difference may be caused by incomplete network, and also by the distinct simulation year (O/D matrix for 1998) compared against 2000 measurement data. An indicator used for validation of public transport is Passenger x km.

The model estimations, assumed to be representative for a typical day, were multiplied by 365 and compared with annual statistics in 1998 [INE]. For bus, the difference between the Passenger x km estimated by the transport model and survey correspond to 20% and for tram this indicator represent 29% difference. - Vehicle speed Vehicle speed is estimated from VISUM outputs considering road length and impedance for each road segment. Based on the estimations, an average vehicle speed for the Lisbon urban area correspond to 23 km.h-1, while outside the city this parameter is 73 km.h-1. A frequency distribution of average vehicle speed for a typical day in the Lisbon Region (including the city) is presented on Figure 12.

- Fleet composition In order to prepare the inputs to the emission model, statistical data on vehicle fleet composition provided by different institutions were processed. The data for 1998, considered as a reference year, were selected always when possible. Otherwise, the year more close to the reference year is used.

Vehicle park registered in AML in 1998 (Figure 13) is characterised by important contribution of passenger cars (79.7%) reflecting the national trend but presenting significantly higher weight than Portuguese average value (63.7%). The Lisbon municipality identifies even more accentuated influence of passenger cars on fleet composition with 85.06% fraction (Figure 14). The role of motorcycles in Lisbon is also verysignificant. As a general trend, LDV reveal to have not very important part in AML rounding about 6% compared with national values (19.4%).

Vehicle age is one of the most important characteristics for the emission estimation. The statistic data provided by ACAP summarise the age distribution of vehicles in circulation in Portugal in 1999 (Table 2). This information is used to calculate relative contribution of each vehicle class in the fleet composition assuming a correspondence between vehicle age and emission standards.

* Only exhaust emission VKT – vehicle*km travelled As could be seen from the results, emissions induced by traffic in Lisbon contribute significantly to the total AML emissions. Pollutants related primary to fuel consumption, such as CO2 and SO2, represent about half of the daily total values. However, for CO, NOx and VOC this relation is more complex and depends on average speed and proportion of vehicles with catalyst. It is also important to recognise that total emission of NOx in AML are higher than VOC, while in the urban area NOx emission is under VOC levels. This fact may be important for future modelling of photochemical pollution. As could be expected, emission rates per capita and per area are always higher for Lisbon in comparison with average AML values. The quantitative information presented in Table 4 stress once again the importance of traffic as emission source in urban areas. Cold-start emission, analysed in this study, demonstrates to be extremely important for the total results with only exception for NOx. The average contribution of cold-start emissions to the total is varying between 14,5 – 31,4 % depending on pollutant (Table 4). At the same time, their maximum contribution can achieve 82%. Table 4.

In order to guarantee the consistency of the quantified emissions, the data completeness of Lisbon emission estimations were analysed in this study. The analysis is based on fuel consumption data. TREM model applied for emission quantification was also used to calculate fuel consumption. Afterwards, these data were compared with fuel consumption statistics available with high spatial resolution. A significant difference between the estimated and statistical values was found for diesel consumption, since the industrial consumption of diesel is also contemplated in statistical report. For gasoline, the model represents overestimation within Lisbon City. The 51% difference is mainly related to the daily income of vehicles from neighbourhoods to this area that is not reflected in fuel consumption survey. It could be expected that Lisbon District statistics represent better the situation and gasoline is sailed and consumed within the same administrative unit. For the Lisbon District the model slightly underestimate gasoline consumption and reveal only 9% difference with statistical data. However, for the entire AML the underestimation correspond to 24% revealing some problems on transport activity data primary in South AML.

3.3 VADIS

3.3.1 Domain definition

The domain defined in Lisbon city centre is located in the city downtown near Tagus river (see Figure 16), between Terreiro do Paço and Rossio, spots of special touristic interest.

As represented on Figure 17, a cluster of rectilinear buildings and perpendicular streets characterise this area, as a heritage of the modern architectural style that characterised the 1755 earthquake reconstruction plan. This residential and commercial area comprehends several one-way roads with an intense flux of traffic and a pedestrian zone, where local hot-spot air pollutants levels are expected to occur. The study domain covers an area of 450 m x 450 m, and the height considered for calculation was of 100 m.

the black rectangle.

3.3.2 Input data description

The buildings and emission sources coordinates definition, the meteorological conditions description and the emissions characterization related to CO, NOx and PM10 pollutants, constitute the main VADIS input data.

Buildings Volumetry Downtown buildings form an homogeneous block of 26 rectangular buildings, all with the height of 15 m, as shown on the 3D perspective on Figure 18. To simplify the obstacles definition process, and as all of the 26 buildings have a 344º orientation, the cartographic grid was rotated according with this alignment.

Figure 20. Lisbon simulation domain (scale 1:4592), represented by the red rectangle, and traffic-

counting stations marked with black dots. The hourly traffic emissions data were estimated using TREM model. The numerical system TREM/VADIS was developed towards the estimation of the atmospheric pollution induced by road traffic in urban areas. The VISUM model gave the needed traffic volume per road segment used by TREM for the estimation of traffic emissions. The hourly variation of CO emissions for the simulation day estimated by TREM model is presented on Figure 21. From this figure, it is possible to notice that the evolution of CO emissions with time is very similar for both streets. On the other hand, this behaviour agrees with typical traffic flux, with smaller values occurring during night and with the increasing of emissions during diurnal hours without clearly defined peaks. The emission sources were introduced as parallelepipeds with a height of 3 m, as a way to implicitly consider vehicle-induced turbulence. VADIS was applied using the CO, NOx and PM10 emissions resulting from road traffic.

From 6 p.m. simulation results presented on figure 22 it is possible to notice higher CO concentration values located in Prata street and adjacent pedestrian streets. This fact agrees with the main winds from Northwest. A quantitative analysis to determine modelling uncertainties has been applied to the estimated CO concentration values. The analysis was based on the maximum deviation of the measured and calculated levels within the considered period. To be compared with modelling quality objectives established by the Directive (2000/69/EC), 8-hour average CO values were evaluated. Based on this approach, the average uncertainty of the model prediction for this study corresponds to 24%, achieving 52% as a maximum for the last simulation hours. This value slightly exceeds the 50% acceptability limit defined by the Directive.

3.4.2. Description of the input data

Input requirements:

Emissions: The hourly non-urban, suburban and urban emission rates are provided in kg/(km2*h) for surface emissions and elevated emissions. It is appropriate that such data are organised in an emission inventory. Meteorology: Meteorological data such as daily average wind speed and direction as well as surface temperature and temperature lapse rate above the mixing layer, thermophysical data and surface roughness depending on the land use are also required. Boundary conditions: Daily average regional background concentrations of NO, NO2, O3 and all other species included in the chemical reaction mechanism. Urban scale background boundary layer concentrations are computed with the three-layer box model embedded in OFIS. Other input requirements: A file with control run data and rural land use.

3.4.3. Results Analysis

Output data

Concentrations of chemically reacting pollutants for each grid location, within the urban plume, as well as average concentration over the whole domain are the outputs of the OFIS model. Annual average concentrations; percentiles and exceedance probabilities of threshold values are also possible OFIS outputs. The analysis of the input data for Lisbon baseline scenario reveals that there are some basic background concentrations missing. In comparison to the GEA results, emissions are lower. Overall, no exceedances are observed and therefore the final reference scenario for Lisbon should be considered as one with zero exceedances (this is why no figure is provided here). This results supports previous findings, that state that for the year 1999, available ozone concentration level information suggest no exceedances above the EU 1-hour threshold and no 8-hour exceedances of the WHO guideline and EU thresholds. Nevertheless, the same reference also stated that “preliminary analysis indicates that daily

exposures in 1999 may have contributed up to 1.6% of all deaths (± 350 cases) and 1.9% of respiratory

Lisbon Municipality has a population of 556 797 inhabitants, in an area of 82 km2. In 1996 the energy consumption was:

- 1260675 TOE.year-1; - 2.264 TOE.person-1. year-1;

- 15374 TOE.km-2.year-1. 3.5.2. Description of the input data

The reference energy system (RES) for the Lisbon aplication domain is mainly dominated by the tranport sector. The Lisbon municipality has no internal energy production and the industry sector has reduced importance when compared with the transport sector (in terms of energy comsumption and emissions). Hence, the biggest efforts in the characterization of the Lisbon RES were made in the transport sector.

In order to run a MARKAL model, several types of data are needed.

Imported energy prices Demand data Residual Capacities Techno-economic data Input/output coefficients, availability and lifetime of technologies Pollutants emissions associated with technologies.

3.5.3. Result Analysis

The MARKAL model has complex input data not always easy to estimate accurately. By that reason, the model input data continues being improved in order to correctly represent reality in the Lisbon city case. The presented results concern the transport sector due to its importance among other sectors in the Lisbon city case. The modeled transport technologies are listed below.

4. City scenarios

All models were run for a baseline situation (2000) and results have been described in the above sections. However as the aim of the SUTRA was to investigate and plan a “City of Tomorrow”, each city ran every model under conditions highlighted in a set of “common scenarios”. Four scenarios were chosen which depicted four variation of change in four parameters: demography, economy, land-use and technology, for the year 2030. Each city ran exactly the same scenario so that comparisons could be made between cities experiencing identical changes by 2030.

4.1 VISUM

In order to implement the four chosen common scenarios it was applied a spreadsheed (CommonScenarios.xls), developed by a working group including: PTV, Municipality of Genoa, FEEM and ARPAL. Using this file it was possible both to modify the O/D matrices, according to the scenarios, and to obtain some indicators about the traffic assignements. In the following pictures, it can be seen the specific input and output values: Table12. Lisbon input data for the common scenario implementation. InputPopulation data 2000

The values of the Sensitivity Factor and Form Factor have been found out through an iterative process in order to achieve the desired distance changes, according to the chosen scenario. The obtained results reflect the characteristic of the Lisbon Traffic network; in fact strong changes in land use likely influence both long distance trips and short ones Sensivity Factor: (1) Densification : 0 ... -1

-0.1 small reduction of long distance trips -0.9 strong reduction of long distance trips

(2) Sprawl : 0 ... 10 1 moderate increase of long distance trips 10 strong increase of long distance trips

Form Factor: >1: strong changes only for long distances 1: linear change <1: strong changes also for short distances

After running the CommonScenarios.xls file, 8 new O/D matrixes were developed for each of the 4 scenarios. In the case of Lisbon, at this time exists one O/D matrix for public transport and another O/D matrix for the private transport, for each of the 4 scenarios. Besides these 8 new O/D matrixes, we also have a matrix for Good Vehicles, for the baseline and for the common scenarios. Next it will be described the steps followed to implement the 4 common scenarios:

1. Add the new O/D matrixes to the 4 new networks (lisboa15_SC1.ver, lisboa15_SC2.ver, lisboa15_SC3.ver, lisboa15_SC4.ver);

2. Modify the link capacities, according to the scenario definition (SC1, SC3: 10%; SC2, SC4: 5%); 3. Do the assignment for each network; 4. Run the PcomTest.exe to achieve lisboa15_SC1.csv, lisboa15_SC2.csv, lisboa15_SC3.csv and

lisboa15_SC4.csv; 5. After the firsts results another indicator has been added: Congestion rate (passenger-

hr/passenger-hr in overcrowded vehicle). So, inside the VISUM network, by an iterative process, it was changed the Total Capacity of the PuT Vehicle Types;

6. Do the assignment again; 7. Run Pcomtest.exe; 8. Analyse the indicator Congestion rate until it achieves the values as the scenario definition (0%

in the virtuous city scenarios and 20% in the vicious city scenarios).

According to scenario definition the best “solution” is the CS1, with decreasing of the private traffic flow and increasing of the public one. For what concerns the value of the “passenger-hr in overcrowded vehicles”, it is due to the considerable increase of the capacity of the public transport vehicles. Regarding the CS3, it could seem better than the first one, but it is necessary to stress that the considerable decreasing of the indicators, in this case, is linked to a shrinking and getting older city.

4.2 TREM

TREM input data for the scenarios consider several technological indicators: penetration rate of new vehicle technologies, vehicle fleet changes and fuel properties. Additionally to the technological indicators, TREM inputs concern different vehicle volumes and speed as provided by VISUM for each of the scenarios.

4.2.1 SC1 – Young and Virtuous

For the scenario SC1, the following input data were considered: 1) 27% penetration rate of New vehicle technologies in passenger cars distributed

between Hybrid Electric vehicles (13%), Electric Vehicles (7%) and Fuel Cell Electric Vehicles (7%);

2) Vehicle fleet composition based on the MEET data for Portugal in 2020 (Figure 31)

4.2.5 Results Analysis Emissions estimated by TREM for the four common scenarios reflect non-linear relation between total amount of the pollutants emitted by transport and the mobility increase. Thus, only CO2 and PM emissions for the scenario 2 represent values above the reference situation. All other pollutants are expected to decrease within scenarios time interval, primary due to emission reduction technologies implemented in new vehicles and low sulphur levels in gasoline and diesel (Table 18, Figure 32).

Figure 32. Comparison of total traffic emissions for the common scenarios with the reference situation (reference situation=100%) Tthe analysis of emission per capita demonstrates that highest values also correspond to the reference situation and in the near future this indicator is decreasing for all the scenarios. The “yang and virtuous” scenario (scenario 1) represents lower emission values (Table 19).

Also, contribution of public transport to the total emissions levels were analysed for the four scenarios. As could be seen from the Figure 33, the scenario 1 represent highest values for this indicator due to increase of public transport share. The analysis of the data highlights elevated contribution of NOx emissions comparatively to other pollutants induced by public transport.

Considering the city scenarios, the local scale model VADIS was applied to the same simulation domain of the baseline scenario and with identical meteorological conditions. The traffic emissions resulting from the VISUM/TREM cascade for city scenarios application was used in order to perform the air quality simulations.

4.3.5 Results Analysis

The analysis of the state indicators for VADIS model for the reference situation and city scenarios in Lisbon application shows an increase of CO, NOx and PM10 concentrations for scenario 2 relatively to the baseline scenario. This situation can be related to the raise of the number of trips and the consequently increase of traffic emissions in a young and vicious city. In scenarios 1 and 3 the peak concentration determined in the simulation domain for each pollutant is lower than the one verified for the reference situation. The scenario 4 presents a similar behavior to the one verified in the actual situation.

Due to the difficulty found in using the VISUM outputs for the Markal scenarios input, mainly due to the differences in the domains another strategy was used in order to calculate Markal inputs for the 4 scenarios. This strategy is only an exercise and it doesn’t intend to replace the MARKAL runs with the VISUM outputs. The effort to adapt VISUM outputs to MARKAL inputs is still present in our work. Strategy description Four main issues were identified to the development of scenarios: demographic, economic structure, technological and land use. The analysis of these driving forces gave rise to four different scenarios, presented in Table 21, that reflect the general response of the Lisbon transport system to “extreme variations” due to general policy strategies.

Scenarios 1 and 2 reflect a young society (population growth and stable youth share), with high tele-work level and high mobility rates. Scenario 1, as well as scenario 3, is a virtuous scenario. It reflects increases in public transport share, in car occupancy rate and decrease of average car trip length due to a mixing land use. It also has high penetration rates of clean transport technologies (fuel cell, electric and hybrid vehicles). In contrast, the vicious scenarios reflect stability in the public transport share, decrease of the car occupancy rate and increase of average car trip length. The rates of penetration in these scenarios of clean transport technologies are low. Scenarios 3 and 4 outline an old society with negative demographic rates decrease in youth share, low telework level and small increase in mobility rate. The variations on indicators that characterize the four main driving forces are reflected in MARKAL by change on transport service demand and share of public transports (Table 21). Some minimum rates of

new technologies penetration were also considered depending on scenarios. The rest of the energy system was left unchanged.

Environmental objectives Two environmental objectives that were translated into emission constraints (E.C.) in the model were considered: (i) It was assumed that the policy in this urban region consists first in reducing the emissions of ozone precursors (NO2 and VOCs mainly); (ii) The second possible environmental objective is to reduce the emissions of CO2 in conformity with Kyoto/Marrakech agreements. Ozone pollution is related to episodes and may be translated through the use of indicators that are built from the prevalence of critical weather conditions over a typical year. When only the precursors due to transportation are considered, it has been found possible to represent in a single linear expression the relationship between the precursor emissions and the O3 pollution indicators. The imposed constraints on the total NO2 emissions due to the transportation sector are indicated in Table 22. The second environmental constraint, imposed on the energy system, concerns the emissions of CO2, the major greenhouse gas derived from combustion. The schedule of emissions bound shown in Table 22 corresponds to an objective of limiting to 6.4 MT.year-1 the CO2 emissions from 2010 onward. This objective is consistent with the Kyoto protocol commitment of Portugal. Table 22. Upper bounds on NO2 and CO2 emissions considered in Lisbon MARKAL-Lite simulations.

When comparing the installed capacity for private transport it can be seen that only for scenario 3 the installed capacity decreases. For all the other scenarios it increases achieving a maximum of 5000 veh.km.day-1 in scenario 2.

For the installed capacity for public transport SC1 and SC3 very high values are achieved. This values were not expected but are explained by the increase of the share of the public transport in these two scenarios. When the share for the public transport is increased in 15% in vehicle-km, the increase in passanger-km increases much more. In the future this increase in the share has to be changed in order to reflect the increase in passenger-km and not in vehicle-km. The increase in the consumption of fossil fuels in these two scenarios is associated with the increase of public transport.

Scenarios 1 and 3, the virtuous scenarios, are the ones that have higher total costs. This fact can be explained by the introduction of new and more expensive technologies.

4.5 OFIS

The OFIS emissions for the 4 scenarios were estimated according to the output of VISUM and TREM models. For each scenario were estimated evolution factors relative to the baseline scenario emissions. Since the OFIS domain is not the same of the VISUM model, it was necessary to do some assumptions.

In the following table are presented the estimated emissions evolution factors used for each the 4 scenarios.

As it was expected, only the SC2 presents emissions evolution factors greater than 1.00, which means that the emissions considered in the OFIS simulation will be bigger than the used in the baseline scenario.

4.5.5 Results Analysis

The next figures provides with an overall summary of the indicators vs scenarios for Lisbon, indicating that the scenario performance is identical, with the pronounced exception of scenario S3. Figure 51 compares the indicators for the scenario baseline and the 4 scenarios concerning the OFIS application results. Scenario 3 produces the most interesting (non zero) results, as it correlated to the lower ozone consumption pollutants, accompanied by scenario 1. It should be notes that the two scenarios result in similar indicators for some of the receptors (like int_ofis for receptor 3), while they correspond to very different indicator values for other receptors, thus pronouncing the influence of the meteorology over emission and concentration patterns.
