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)
