Active transportation planning with PTV Vistro’s traffic signal workflows.

  • PTV Vistro is your active transportation analysis tool.

    Understanding how pedestrian and bicycle facilities operate fosters safe and efficient designs for vulnerable users. This knowledge is critical in the development of active transportation plans and complete streets projects. Additionally, PTV Vistro’s traffic workflows include industry-standard methods. Also, this functionality enables planners and engineers to optimize and prioritize active transportation modes and support recommendations.

Leading pedestrian intervals and exclusive pedestrian phase evaluations

  • Solutions like Leading Pedestrian Intervals (LPIs) at traffic signals are wide-spread active transportation plan features. Advantageously, PTV Vistro’s built-in Delayed Vehicle Green input easily creates LPIs. This setting enables you to accurately evaluate, optimize, and coordinate LPI operations across your network. In addition, PTV Vistro includes build-in functionality to analyze exclusive pedestrian phases, allowing all pedestrians to cross safely while vehicular traffic has all-red signals.

Active transportation analysis methods

  • Notably, PTV Vistro’s pedestrian and bicycle evaluations provide cost-effective analyses. In fact, the Highway Capacity Manual's 6th Edition methods systematically measure your solution’s multimodal deficiencies and effectiveness. Pedestrian outputs include crosswalk and corner circulation measurements, delay, LOS score, and crosswalk LOS. In addition, bicycle outputs report the saturation flow rate, capacity, delay, and LOS score and grade. These measures evaluate both dedicated and shared lane facilities.

Cycle tracks and more

  • Moreover, PTV Vistro optimizes signal timings for parallel cycling facilities. Utilizing coordination Route functionality, Vistro produces specialized analyses of cycle tracks in the time-space diagram. Uniquely, this powerful feature enables you to prioritize green times along your signal corridor. This increases service reliability and reduces frustrating stops for bicyclists; thus, balancing complete streets operations.

Active transportation simulations and animations

  • Finally, visualize your active transportation plan solutions and supplement your evaluations with PTV Vissim. This adds robust 3D animations capabilities. Foremost, simulating pedestrian and bicycle interactions visually confirms your LPIs and cycle-track operations. Furthermore, these realistic simulations effectively communicate your project decisions to stakeholders. Vissim animations give you strong public involvement content like images and videos. Above all, the easy migration from Vistro to Vissim makes the simulation of active transportation solutions budget-friendly.
