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

> 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

> Speed, Road Name, and Link Closure

> On-ramp Speed Must be Adjusted to match up with Mainline Speed

(Merging Behavior Issue)

> Turn Type and Turn Closure

> All Turn Types on Freeway segments are set to “2. Straight”.

> ANM Import sets Reduced

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

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)
