PTV OPTIMA

The mobility of goods and people is a critical issue of concern to our society. Thus, the ability to forecast traffic conditions realistically and to decide on optimal trips for road users and vehicles allows individuals and companies to plan their activities more efficiently. This adds up to substantial savings for the society as a whole.

Today, a vast amount of data, like flow, density and speed from roadside detectors as well as travel times from Floating Car Data (FCD) or Automatic Number Plate Recognition (ANPR) systems is available – as historical and real-time data. At the same time, there are mobile communication technologies that support dynamic decision-making and adaptive strategies that provide road users with real-time traveller information. First projects approve that the benefit of these already existing data sources and tools can be enhanced significantly through PTV Optima. PTV Optima is the modelling technology providing an accurate forecast of traffic flow and road congestion. It propagates the traffic data measured on only some of the network links in space and time and calculates a comprehensive traffic state estimation and forecast on all links of the network for up to one hour.

PTV Optima reaches a high level of precision in short term traffic predictions over the whole graph. FUNCTIONS AT A GLANCE PTV Optima allows you to: � calculate real-time traffic state and

forecast the development for up to one hour (flow, speed, density and queue)

� forecast the traffic state with respect to traffic management strategies and current incidents, improving the decision making capabilities of the operators even before problems occur

� calculate customizable Key Performance Indicators (KPI) to quickly assess the results

� combine these with methodologies of PTV Visum Safety to get Key Safety Indicators (KSI)

� reliably estimate travel times on each network link

� use the results for navigation or routing by providing the data to third party technologies

KEY ADVANTAGES � Only limited amount of observed data

needed � The software can operate standardized

third party information and utilize a wide range of detector data (roadside detectors, FCD, ANPR)

� Existing tools for traffic monitoring and control can be used

� Reliable travel times varying during the day

� Real time traffic information is elaborated

� The software is scalable and replicable � Open interfaces for seamless

integration into large-scale traffic solutions

� Clear user interface ensures easy handling

CAN STREETS BE ONE STEP AHEAD?
