“PTV Optima is the key to successful traffic management,” says Miller Crockart, VP sales & marketing 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 – also for unforeseeable situations.”
In contrast to a purely statistical approach, which compares times observed with historical samples, Optima’s 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). These provide aggregated information about the overall situation in the network and they offer a good basis for quick decision-taking. KPIs can be set flexibly in PTV Optima – regardless of whether the user’s goal is to prevent congestions and emissions, improve reliability of the traffic network, minimise travel times or reduce the negative effects of planned and unforeseeable events.
“What we experience worldwide, is: monitoring your network only was a yesterday’s task”, says Crockart. “Today traffic managers additionally want to interpret their network and predict the effects of their measures before implementation. That’s why more and more public authorities focus on real-time traffic simulation and opt for PTV Optima.”
