Types of zones
Person AreasGenerate person Trips
Traffic ZonesGenerate vehicle only trips
Transition ZonesZones attached directly to an area where a person trips is generated and then immediately placed into a vehicle before entering the network
Parking ZonesZones where People transition into or out of Vehicles

Challenges associated with parking
• Balancing the cost of different types of parking• Appreciating the effect of the pedestrian
network• Avoiding disproportionate parking turnover• Avoiding unnecessary searching

Table 11.1 Microsimulation Link and Turn Target Calibration/Validation Criteria (Core Area)
CORE AREA
Topic Criteria
Link or Turn Results to be tabulated in appendices and summarised in main report
Tolerance limits for core area:
Flows < 99 – to be within 10 vehicles of observed value
Flows 100 to 999 – to be within 10 per cent of observed value
Flows 1000 to 1999 – to be within 100 vehicles of observed value
Flows > 2000 – to be within 5 per cent of observed value
100 per cent of observations to be within tolerance limits
Plots of observed vs modelled hourly flows required for all observations
Plots to include lines showing core tolerance limits
R2 value to be included with plots and to be > 0.95
Slope equation to be included with plots (intercept to be set to zero)
Table 11. 5 Microsimulation Travel Time Target Validation Criteria
Topic Criteria
Journey Time Average
Average modelled journey time to be within 15 per cent or one minute (whichever is greater) of average observed journey time for full length of route. Each route should be cumulatively graphed by section as shown above
Section Time Average
Average modelled journey time to be within 15 per cent of average observed journey time for individual sections
Journey Time Variability
Average and 95 per cent confidence intervals to be plotted for observed and modelled travel times for each journey time route. Comparison to be to modeller and RMS satisfaction.
