Multi-Modal Microscopic Simulation

PTV has successfully applied VISSIM to analyze and answer diverse transportation questions facing hundreds of communities throughout North America. After understanding the needs of our clients, our approach to these projects is from a systems perspective. The transportation system is composed of many elements (e.g., freeways, transit, arterials, pedestrian areas, bike routes, stadiums, etc.) that work together to serve the mobility needs of a given area. Improvements to one element may influence the performance of another element. VISSIM enables us to merge all or a portion of these elements together in order for stakeholders to better understand the benefits and impacts of various alternatives. The proven and industry-accepted analysis capabilities of VISSIM provide credible technical information to the decision making process. The technical analysis results are complimented by VISSIM’s graphical animation that allows complex and technical alternatives to be clearly and concisely explained to elected officials, technical staff and the public.

The types of projects cover the multi-modal spectrum with examples including:

Freeways

Active Traffic Management
Managed lanes (e.g., HOT + HOV lanes)
ITS assessments (e.g., ramp metering)
Incident management + evacuation planning
Non-traditional interchange and intersection assessments

Arterial streets

Adaptive signal control
Railroad preemption
Access management
Software- and hardware-in-the loop simulation

Transit

Bus rapid transit
Light rail transit and streetcar
Transit signal priority
Conditional priority
Multi-modal centers

Pedestrians and Bicyclists

Multi-modal transit/transfer centers
Pedestrian and bike LOS analyses
Shared and exclusive bike lanes
Evacuation planning
Transit platforms

Additional Applications

Ferry terminal analyses
