PTV Group Optima traffic management
“PTV Optima is the key to successful traffic management,” says Koenraad Verduyn
Managing traffic involves increasingly complex challenges so PTV is here at Intertraffic to advise traffic operators that to make life easier, they should set up their traffic management in future-oriented fashion and rely on a solution which reacts to their network. That solution is PTV Optima which the company is highlighting.

“PTV Optima is the key to successful traffic management,” says Koenraad Verduyn, director direct sales traffic software at PTV Group. “This solution offers precise, real-time traffic information for the entire traffic network and produces reliable forecasts for the next 60 minutes, as well as for unforeseeable situations.”

PTV Optima’s model-based approach makes this possible. In contrast to a purely statistical approach, which compares times observed with historical samples, the model-based simulation approach relies on a physical interpretation of the traffic network and conditions.

The underlying model which describes these relationships allows a simulation for the calculation of information whose measurement is not possible or is only possible with difficulty. This is how the future traffic situation and the effects of various combinations of traffic management measures and disturbances can be simulated.

For troubleshooting, traffic management centres set different goals which can be measured using key performance indicators (KPIs). KPIs provide aggregated information about the overall situation in the network and they offer a good basis for quick decision-taking. They can be set flexibly in PTV Optima – regardless of whether the user’s goal is to prevent congestion and emissions, improve reliability of the traffic network, minimise travel times or reduce the negative effects of planned and unforeseeable events.
