Traffic Signal Operations with PTV Vistro

  • Robust traffic signal optimization

    Achieve the best cycle lengths, splits, and offsets with PTV Vistro’s signal optimization algorithms. You can easily use the traffic software to optimize signals and test timing plans for a single intersection, an entire network, or a specific route. You can even use PTV Vistro to test impacts of new trips or rerouted trips for detours and events and then optimize the signal corridor for these events. It is the perfect tool for traffic signal operations as it stores historical traffic count data at the intersection as well as a test of signal timing in mitigations.

Intersection, network, and route optimization

  • For a single intersection or multiple intersections that are not coordinated with other intersections, PTV Vistro offers local optimization of cycle lengths and splits. In contrast to the local optimization, the network optimization considers the interaction between the signalized intersections. PTV Vistro is unique in that it provides the ability to define specific "routes" for optimization. This means that you have total control over finding the best solution that fits your objectives.

    PTV Vistro has an intuitive workflow for setup and develop traffic signals timing and traffic signal operations optimization. The optimization used the highway capacity manual (HCM) or Canadian Capacity Guide (CCG) to determine measures of effectiveness (MOE) or KPIs. The Traffic Signal Workflow is used to set up ring-barrier traffic singal controllers and develop green bands, or green waves for traffic signal optimization or a traffic impact analysis study.

Instant visual output

    PTV Vistro has a time-space diagrams for traffic signal network coordination and optimization. The TSD using the coordination groups, or zones, traffic signal offset references to calculated the green band, or green wave for traffic signal optimization or a traffic impact analysis study.

  • PTV Vistro offers instantaneous visual feedback through the signal timing diagram showing the green, amber, and all red times for each movement at a specific intersection. It also provides a powerful output through the optimization results graph, details about the optimization process, and visual representation of the output through a time-space diagram.
