PTV working on V2X based traffic management system

“We are developing a network that enables traffic management systems to “interact” with in-vehicle information and assistance devices as well as with infrastructure units,” explains project manager Dr. Michael Ortgiese, Vice President Research & Innovation at PTV Germany.

Future traffic management will allow vehicles and gantry signs to “communicate” with each other. A novel information network between drivers, vehicles and roadside infrastructure is the key. New technologies will combine traffic information centres, roadside infrastructure and intelligent vehicles. PTV analyses these scenarios together with numerous members of the Aktiv research initiative.

“Our aim is to reduce the probability of traffic congestion by 15% and to increase road capacity by 10%,” says Michael Ortgiese. For almost three decades PTV has been focussing on truly innovative optimisation technology for traffic and transportation. As a member of the Aktiv research team, PTV provides technology for traffic information collection and processing, for road network optimisation and dynamic navigation included in cooperative vehicle-infrastructure systems.

“A completely new approach is used which includes infrastructure such as gantry signs, traffic signals or construction sites in the information cycle in order to enhance traffic management“, says Ortgiese. So-called roadside units fitted to gantries collect information sent from passing vehicles. It will also be possible to directly transfer traffic information to the vehicle and to use driver assistance systems for further data processing. Faster provision of information proves to be particularly valuable regarding road safety near construction zones.

Adaptive navigation is an application in networked traffic and transportation. The navigation system analyses data from traffic information centres and services. Additionally, it permanently receives information about traffic conditions and travel speeds of other road users. Moreover, it can take strategic route recommendations into account.

The virtual traffic guidance system of a traffic management centre edits the vehicle data and the data collected by stationary units, such as induction loops or sensor systems. The recommendations are then transmitted to the vehicles by means of gantry signs, roadside units (RSU) and a central service platform.
