PTV Epics in PTV Vissim – model based local traffic signal control for public transport prioritisation (with free demo version)

PTV Epics is specifically designed to reduce traffic planning effort.

The cars had begun stacking up at the intersection, and there is no turning back. Traffic congestion is a big problem for everyone, especially within the city. But what can be done? Maybe take a second off at the red-light timer? Or add a few at the light at the intersection where traffic merged?

One of the main reasons why there’s more congestion is due to more cars on the road, coupled with lack of proper infrastructure. For decades, city engineers have managed city traffic woes and manually attempting to ease the jams. But even with the help of many technologies out there, none can solve this issue as good as PTV Epics, a software tool for traffic-adaptive network control.

While it takes time to fine-tune traffic signal controls to maximise their potential, PTV Epics is specifically designed to reduce planning effort while achieving high-quality results and giving control about priorities regarding different modes (private traffic, public transport and pedestrians) in the hands of the planner.

Interested to see how it works? There is a fully integrated version in the demo version of PTV Vissim available here – under the “Examples training” folder and then click on “Signal Control” and look for “Tram Priority PTV Epics”.

You can also find a short introduction of PTV Epics here.

For a complete package, you may also check out PTV Balance, the “big brother” of PTV Epics. While PTV Epics takes care of single intersections, PTV Balance considers the network and takes care of the coordination of up to 50 intersections at the same time (hence enabling “green waves” and specifically reducing the number of stops).

Going even further into the realm of full-scale operational traffic management, PTV also offers PTV Optima, the tool for real-time traffic management centres, providing short-term forecasts for large areas and decision support. PTV Balance and PTV Optima work together specifically to increase their respective potential to improve traffic flow.
