MOTION-a new on-line traffic signal network control system

HERMES is a DRIVE II project which focuses mainly on the enhancement and application of traffic control strategies that are based on on-line origin/destination information automatic incident detection. The biggest workpackage within HERMES aims at the development of a new on-line traffic signal network control system named MOTION (Method for the Optimization of Traffic Signals In Online controlled Networks) This work is to some extent based on results already achieved previously in a project study made for the SIEMENS AG and in the DRIVE I project ODIN, where algorithms for the on-line estimation of origins and destinations of the major streams at single intersections and in wider urban road networks have been developed together with initial concepts for the use of this information in traffic control. Simulation results have already shown that improvements of 8% to 20% in the traffic performance are possible, if signal control schemes are based on O/D-information.<
