EmerT – a web based decision support tool for Traffic Management

Abstract

This paper describes the EmerT portal (Emergency mobility of rescue forces and regular Traffic), an extended version of the DELPHI web tool. EmerT is a web decision support application for real time traffic situation, prognosis and traffic simulation. One of the main features in this system is to provide traffic state estimation and forecasts with use of the mesoscopic traffic simulation. Traffic bottlenecks can be identified by the simulation which helps the decision maker to take appropriate traffic management actions. Another feature is the information exchange and cooperation between the Traffic Management Center, Emergency Rescue Services, Police and Emergency Call Center. This application supports three demonstration regions in Germany, Cologne, Bonn and Munich, and will be extended for the whole region of Germany. The main purpose is to handle major incidents and large events which affect changes in the traffic demand and current traffic situation. The EmerT system supports users to get a quick overview of the current traffic situation. This paper aims to present the current development state of the EmerT portal with focus on the backend including traffic simulation, data acquisition and aerial imaging.
