Introducing "Strategic Routing"
Technological milestone for the CVIS research project: Traffic and transportation strategies can influence route recommendations
Dortmund/Karlsruhe, November 11, 2009. Good news for local residents. New routing procedures clear the way for alternative route recommendations, without routing traffic through residential areas. The PTV AG transportation experts from Karlsruhe developed the trendsetting technology as part of the CVIS (Cooperative Vehicle-Infrastructure Systems) research project. It is being presented to the public today with live driving demonstrations on the Dortmund test area.
In a final presentation, Siemens, the City of Dortmund, Ertico and PTV will show their results on "cooperative" systems. They concern the interaction between vehicle, infrastructure and traffic management centres. The implemented procedure is a technological milestone for cities, counties and regions. For the first time, public authorities are able to use PTV's new technologies and stored transportation strategies to influence route recommendations. As a result, traffic flows freely through specified routes, avoiding congestion. For example, navigation systems will no longer guide the driver through residential areas - meaning that congested city centres could soon be a thing of the past.
“The major advantage of strategic routing is the prompt availability of route information,” explains Dr. Michael Ortgiese, who is responsible for research at PTV. Until now, dynamic routing has been working with time delays, as it only comes into action after disruptions have occurred. The strategic version informs the driver in advance and traffic can be controlled as required. Michael Ortgiese is convinced, "This will create immense added value for traffic control, not only in city centres, but also in surrounding areas for roadworks or major events".
How does strategic routing work?
The crucial question here is: How can traffic and transportation strategies be managed and communicated in the future? The answer is: using a specially developed strategy workplace. PTV has now laid the necessary groundwork.
The central strategic routing installation sends the client requesting the route (mobile device) a dynamically strategic alternative route. The driver also receives information on the incident which activated the strategy.
The information flow occurs mutually between vehicle and control centre. Information is provided on traffic situations which lead to pre-defined strategies being triggered. Examples of these are "Congestion", "Tailback dispersed" or "Slippery roads". These are sent by the individual vehicles as message to the control centre and visualised there. The strategies planned by experts are available in the control centre. They are activated and sent to the vehicle depending on the traffic situation or as planned traffic control scenario, for example during bridge work.
The CVIS project
The aim of the research project is to use cooperative systems to improve traffic flow, increase safety and to minimise the negative effects of traffic on the environment. CVIS is sponsored by the European Union and runs from 2007 to 2010. Over 60 international partners from diverse industries are working on many sub-projects. Technology for cooperative traffic and transportation management in inner-city areas was developed and tested as part of the sub-projects COMO (Cooperative Monitoring) and CURB (Cooperative Urban Applications).
