EXECUTIVE SUMMARY
METRO is actively working towards the implementation of Light-Rail Train (LRT) linesalong Rusk Street and Capitol Street within the City of Houston downtown area. The purpose of
the downtown LRT simulation study is to determine the level of impact the proposed METRO
light-rail lines may have on the following four car garage driveways along Rusk Street and
Capitol Street. In addition, general operational conditions with LRT simulation weredocumented, in particular the impact of LRT on the north-south roadways within the study limit.
Bank of America building on Smith Street (entrance and exit)
Pennzoil Place building on Capitol Street (exit only)
Esperson Garage on Rusk Street (entrance only)
Heritage Plaza on Rusk Street; or also known as 801 Travis Garage (entrance and exit)
The study methodology was to collect data at the garage driveways to estimate operational
conditions with existing lane configuration and existing traffic control conditions; and then to
compare the results with operational conditions of the garage driveways with LRT simulationusing METRO buses with future lane configuration. The primary performance measure used to
compare operational condition of the garages is average vehicular delay (sec/veh), while the
secondary performance measure used for comparison is maximum back-of-queue (veh) at the
garage driveways. Please note that this study did NOT measure the impact of LRT on thedowntown street network.
In order to capture the typical two primary morning and afternoon peak periods, the projectteam met with building management representatives to determine the morning study hour (7:30
am to 8:30 am), and the afternoon study hour (4:30 pm to 5:30 pm). Data was collected at each
garage driveway for a total of four days to establish two sets of comparison days. The two
existing condition and with LRT simulation comparison days are summarized below.
Day 1 Comparison Tuesday, October 26, 2010 (existing condition), November 09,2010 (with LRT simulation)
Day 2 ComparisonWednesday, October 27, 2010 (existing condition), November 10,
2010 (with LRT simulation)
Study Findings
Table 2 summarizes performance measures collected at the garage driveways. In general,average delay comparison at the driveways on Day 1 and Day 2 are well within an acceptable
level of operation. Figures 5 and 6 also show average delay comparisons of Day 1 and Day 2,respectively in a graphical form. The maximum back-of-queue comparison appears to be withinan acceptable level as well. In addition, the results reflect the operation at the driveways is
highly influenced by the operation of the gate mechanisms and off-duty officers directing traffic;
more than traffic level including LRT on Rusk Street and Capitol Street.

Conclusions
In general, average delay comparisons of Day 1 and Day 2 are within acceptableoperational parameters. In addition, the comparisons of the difference between the
existing condition and with LRT simulation average delays are not statistically
significant.
The signal timing and closely spaced signalized intersections within the downtown area
meter traffic entering the driveways, and provide sufficient gaps for exiting traffic from
the driveways. This is the primary reason why high levels of maximum back-of-queues
are not observed at the garage driveways (maximum 4 vehicles). Day 1 and Day 2comparisons did not show a statistically significant difference.
North-south roadways within the study area are congested during the morning andafternoon peak periods mainly due to heavy traffic along the north-south streets. Capitol
Street and Rusk Street traffic appears to not impact the north-south roadways within thestudy limit. During the observation of north-south roadways, we found that off-duty
officers stopping vehicles to facilitate traffic to/from the garages appear to cause back-
ups on Capitol Street and Rusk Street, and in some instances blocking at a maximum onelane of traffic on the north-south streets, but never the entire north-south street. Inaddition, these back-ups almost always clear-out within one cycle period.
In general, the operational levels of the garage driveways seem to be controlled by thegate mechanisms and efficiency of patrons going through the gates. As an example, at
801 Travis garage, the exit lane gate mechanism broke down during an afternoon peakperiod study. Therefore, we had to stop data collection until the gate was functional
again.

INTRODUCTION
METRO is actively working towards the implementation of Light-Rail Train (LRT) linesalong Rusk Street and Capitol Street within the City of Houston downtown area. The purpose of
the downtown LRT simulation study is to determine the level of impact the proposed METRO
light-rail lines may have on the following four car garage driveways along Rusk Street and
Capitol Street. Figure 1 illustrates the study area and details of the four garage driveways. Inaddition, general operational conditions with LRT simulation were documented, in particular the
impact of LRT on north-south roadways within the study limit.
Bank of America building on Smith Street (entrance and exit)
Pennzoil Place building on Capitol Street (exit only)
Esperson Garage on Rusk Street (entrance only)
Heritage Plaza on Rusk Street; or also known as 801 Travis Garage (entrance and exit)
The study was conducted in collaboration with various groups within the City of Houstonincluding but not limited to the Mayors Office, Public Works and Engineering Department, and
Parking Management Division. In addition, various outside organizations participated in the
study, including METRO, Houston Downtown Management District, and the buildingsmanagement team. To accomplish the Downtown LRT simulation study; numerous coordination
meetings were held by the participating organizations to complete the study.
STUDY METHODOLOGY
The study methodology is to collect data at the garage driveways to estimate operational
conditions with existing lane configuration and existing traffic control conditions; then to
compare the results with operational conditions of the garage driveways with LRT simulationusing METRO buses with future lane configuration. It is critical to note that this study did NOT
measure the impact of LRT on the downtown street network.
The primary performance measure used to compare operational condition of the garages is
average vehicular delay (sec/veh) while the secondary performance measure used for comparison
is maximum back-of-queue (veh) at the garage driveways. The 2000 Highway Capacity Manual
(HCM) provides models for estimating control delay at unsignalized intersections. A qualitativedescription of the various service levels associated with unsignalized intersections are provided
to evaluate operation of unsignalized intersections. Control delay as described in the HCM
includes deceleration and acceleration delay in addition to resembling stopped-delay at anintersection. Average delay data collected at the garage driveways is not the same as control
delay, but it resembles stopped-delay as described in the HCM. Nevertheless, here are the
reasons why it is different:Delays experienced by vehicles at the garage driveways are heavily influenced by the
operation of the gate mechanism and the familiarity of drivers going through the gates.
Off-duty officers assist vehicles coming in and out of the driveways against conflictingpedestrians and vehicular traffic, which influences delay data collected as part of this
study.
Pedestrian impedance coming in and out of the garage driveways is much higher than the
typical unsignalized intersection operation as described in the HCM.

Therefore, the data that was collected as part of this study is simply labeled as average delay(sec/veh), and the following simplified evaluation criterion as shown in Table 1 was developed
to see if the garage driveways are operating within acceptable parameters on Day 1 and Day 2
comparisons.
Table 1
Garage Driveways Average Delay Operational Criterions
Operational Criterion Description of Operational Criterion at the Garage Driveways
GOOD
(0 to 30 sec/veh)
Nearly all drivers find freedom of operation, but some drivers begin to consider the delayan inconvenience.
Very seldom is there more than one vehicle in queue, but occasionally there is morethan one vehicle in queue.
MODERATE
(30 to 40 sec/veh)
Often there is more than one vehicle in queue.
Most drivers feel restricted, but not objectionably so.
CONGESTED
(40 and higher sec/veh)
Represents a condition in which the demand is near or equal to the probable maximumnumber of vehicles that can be accommodated by the driveway, and sometimes it isforced flow of traffic.
There is almost always more than one vehicle in queue and backs-up way beyond the
gate mechanisms.
Drivers find the delays approaching intolerable levels, and sometimes the garagedriveway represents failure in traffic flow.
In order to capture the typical two primary morning and afternoon peak periods, the project
team met with building management representatives to determine the morning study hour (7:30
am to 8:30 am), and the afternoon study hour (4:30 pm to 5:30 pm). Data was collected at eachgarage driveway for a total of four days to establish two sets of comparison days. The two
existing conditions and with LRT simulation comparison days are summarized below.
Day 1 Comparison Tuesday, October 26, 2010 (existing condition), November 09,
2010 (with LRT simulation)
Day 2 ComparisonWednesday, October 27, 2010 (existing condition), November 10,2010 (with LRT simulation)
Existing condition data collection was conducted without much advertisement to the public
to ensure drivers behave naturally within the downtown area. Typical parking restrictions were
allowed as is today during the morning and afternoon peak periods. Figure 2 shows the existinglane configuration of Rusk Street and Capitol Street when data was collected at the garage
driveways for existing condition.
Data collection with LRT simulation was conducted using three buses as two sets of LRT
simulators. The following additional measures were implemented to simulate conditions as it isplanned to be after implementation of the proposed LRT.
Parking meters along Rusk Street and Capitol Street within the study limit werebagged by the Parking Management Division.
Lane reduction due to the proposed LRT implementation along Rusk Street and
Capitol Street was achieved by using traffic control cones during the study periodsbased on the proposed pavement marking plan provided by METRO. Figure 2 shows
lane configuration with LRT simulation condition.
All construction related lane closures were kept the same within the study limit.

Figure 3 shows the LRT simulation route and the proposed LRT station locationswhere simulator buses stopped to simulate the proposed LRT lines. The average
dwell time LRT simulator buses stopped at the proposed stations was 20 seconds.
Appendix A shows time schedule of simulator buses that METRO provided to the
City of Houston, which indicates a service frequency of 6 minute runs. Two sets of
LRT simulators (the first set with two buses and the second with one bus) run thesimulation route, stopping at the proposed LRT stations every 6 minutes.
Existing signal timing plan was not altered and LRT simulator buses used the most
southern lanes on Rusk Street and Capitol Street, sharing the lane with vehicular
traffic.
Data collection was performed at each garage driveway using arrival and departure timestamp software on a laptop computer. In case the data collection results were compromised on
the laptop computer, the study team used a digital video recorder as a backup feature. Thesoftware is capable of recording arrival and departure time stamps using the computer master
clock, which allows computation of average delay, maximum back-of-queue, and the number of
vehicles at the garage driveways.
Arrival times for entrance driveways were recorded exactly when a vehicle reached the
standing queue and stopped; or if there are no queue present, when the front of the
vehicle crossed over the curb line.
Departure times for entrance driveways were recorded when the back of the vehiclecrossed over the curb line and approached the gate mechanism.
Arrival times for exit driveways were recorded exactly when a vehicle reached thestanding queue and stopped; or if there are no queue present, when the front of the
vehicle reached the curb line.
Departure times for exit driveways were recorded when the back of the vehicle crossed
over the curb line.
STUDY RESULTS
Table 2 summarizes average delay (sec/veh), maximum back-of-queue (veh), and thenumber of vehicles per hour at each garage driveway for each peak study time period for Day 1
and Day 2 comparisons. Appendix B contains raw data and calculation of the performance
measure outputs that are presented in Table 2. The level of traffic demand along Rusk Street and
Capitol Street, as summarized in Figure 4, appear to be ideal conditions for comparison of Day 1and Day 2 conditions to quantify and analyze the impact of the proposed LRT lines on the
operation of the four garage driveways.

The primary performance measure used to compare the operational condition of thegarage driveways is average vehicular delay (sec/veh). In general, average delay comparisons of
Day 1 and Day 2 are within acceptable operational parameters. As Table 2 shows, on average,
the comparisons of Day 1 and Day 2 are not statistically significant to quantify the impact ofLRT on the operation of the garage driveways. As Figures 5 and 6 show, Day 1 and Day 2
comparisons respectively, the garage driveways are operating GOOD. Sometimes, when thereare other influencing factors such as off-duty officers, gate mechanism malfunction, and heavy
pedestrian traffic, the driveways may operate MODERATE during both existing and with LRTconditions. In addition, back-of-queues are well within acceptable parameters at the garage
driveways (maximum 4 vehicles) during Day 1 and Day 2 comparisons, which do not show a
statistically significant difference.
Another item that was observed in the field during the existing and with LRT conditionswas the impact of the proposed LRT on north-south roadways within the study area. This was
accomplish simply by observing all signalized intersections within the study limit, and then
documenting how many times during the analysis period north-south streets were blocked due totraffic on Rusk Street and Capitol Street. A single investigator observed one signalized
intersection and filled out a form documenting how many times a blockage of north-southroadway occurred due to traffic spill-back of Rusk Street and Capitol Street. Appendix Cincludes observation results of each intersection. Below are the results of our observation and
Figure 7 illustrates potential queue spill-backs that may occur due to LRT implementation.
During both existing and with LRT conditions in comparison Day 1 and Day 2, completeblockage of north-south roadways due to traffic on Rusk Street and Capitol Street was not
observed. The north-south streets within the study limit are congested primarily due tothe large number of vehicles that are coming to downtown in the morning and leaving
downtown in the afternoon peak periods.
With LRT simulation condition including the reduction of one eastbound lane on the westapproach of Rusk Street/Milam Street intersection caused seven spill-back queues during
the morning peak period that extended back to block only the northbound diamond-laneat the intersection of Louisiana Street/Rusk Street. All seven spill-backs pretty much
dissipated within one cycle and the queue spill-back did not block northbound through
traffic lanes of Louisiana Street at any time.
Due to the combination of the proposed LRT station on the east approach and theproposed removal of exclusive westbound left-turn lane at the intersection of Smith
Street/Capitol Street, queue spill-back through the intersection of Louisiana
Street/Capitol Street was observed when LRT simulators were dwelling at the proposedstation location. The queue was mainly isolated along the northbound exclusive left-turn
lane at the intersection of Louisiana Street/Capitol Street. The spill-back queue
dissipated within one cycle and it did not impact the northbound through traffic lanes ofLouisiana Street at any time.

The Rusk Street/Milam Street intersection caused seven spill-back queues during
morning peak period that extended back to block only the northbound diamond-
at the intersection of Louisiana Street/Rusk Street.
At the shared LRT and vehicular lane of the Smith Street/Capitol Street intersection,
queue build-up through the intersection of Louisiana Street/Capitol Street was observed
when LRT simulators were dwelling at the proposed station location.

CONCLUSIONS
In general, average delay comparisons of Day 1 and Day 2 are within acceptableoperational parameters. In addition, the comparisons of the difference between existing
conditions and with LRT simulation average delays are not statistically significant.
The signal timing and closely spaced signalized intersections within the downtown areameter traffic entering the driveways, and provide sufficient gaps for exiting traffic from
the driveways. This is the primary reason why high levels of maximum back-of-queues
are not observed at the garage driveways (maximum 4 vehicles). Day 1 and Day 2
comparisons did not show a statistically significant difference.
North-south roadways within the study area are congested during the morning andafternoon peak periods mainly due to heavy traffic along the north-south streets. Capitol
Street and Rusk Street traffic appears to not impact the north-south roadways within the
study limit. During the observation of north-south roadways, we found that off-dutyofficers stopping vehicles to facilitate traffic to/from the garages appear to cause back-
ups on Capitol Street and Rusk Street and, in some instances, block at a maximum one
lane of traffic on the north-south streets, but never the entire north-south street. Inaddition, these back-ups almost always clear-out within one cycle period.
In general, the operational levels of the garage driveways seem to be controlled by thegate mechanisms and efficiency of patrons going through the gates. As an example, at
801 Travis garage, the exit lane gate mechanism broke down during an afternoon peak
period study. Therefore, we had to stop data collection until the gate was functionalagain.
