Project Boundary

> Freeways: At least two interchanges and/or two miles outside of study

area.

> Ramp Terminal Intersections: One intersection outside of the study

intersections.

Time Periods

> AM Peak Period – 4 hours, 6:00 ~ 10:00

> PM Peak Period – 5 hours, 14:00 ~ 19:00

Volume Data Interval

> Traffic volumes should be collected in 15-minute increments

VISSIM Network Calibration

Calibration Measures

> Volume Data: Peak 2-hour Ramp Volume

> 15-minute Average Speed on I-5 Mainline

(Entire simulation period, PORTAL)

> Visual Check

Calibration Method

> Comparison of Field Data and Simulation Output (3-days)

> Iterative Process until it matches

VISSIM Network Calibration

Calibration Parameters

> Wiedemann 99 Model Parameters

> Headway Time (CC1) : Headway Time directly impact Safety Distance

calculation process in VISSIM

> Lane Change Behavior Parameters

> Deceleration Rates

> Safety Distance Reduction Factor

> Max. Deceleration for Cooperative braking

> Lane Change Distance

> It should be long enough so that cars which needs to use certain connector

can complete necessary lane change behavior safely.

Conclusions

> Network geometry, volume, and signal control coded and maintained

in single platform.

> Detailed geometry coding saved time in latter steps.

> Demand development and adjustment could be completed effectively

with VISUM.

> Calibration result of VISSIM network were acceptable (Speed,

Volume).

> Project completed in ~ 200 hours.

> Additional scenario with different demand level can be simulated with

minimal effort

40


More Conclusions

> PTV Vision - Complete framework and toolbox for long-term

sustainability of macro-meso-micro simulation modeling

> Comprehensive and Flexible Network [Planning -> Operations]

> More realistic demand

> Complementary diagnostic tools [HCM, queueing]

> PTV Vision – More Tools

> Flexible DTA Support [DUE, VISTA, Dynus-T]

> Traffic Count Management (TCM) provides project analysis support

– Count data quality (includes speed)

– Management and utilization (VISUM export)

– Expanded simulation analysis (VISSIM import)
