A system to reduce congestion and improve travel time reliability: application in Patras, Greece

The present paper investigates traffic congestion and travel time reliability trends in the city of Patras. In 2006, after close cooperation of the various local authorities involved with the University of Patras, a new system was developed and proposed to relieve congestion and improve travel reliability. It is based on the establishment of two, so-called, fast traffic routes; these actually are two highways of 12 km total length. To achieve this establishment, car parking was entirely prohibited, traffic signals were reprogrammed, electronic devices were put in operation to control traffic and parking violations. The results of this system were assessed by a performance measurement scheme; the system was adopted with relief by the majority of civilians. Travel time reliability, how it is defined and how it is measured, the traffic measures' strategy and the performance assessment are presented in detail in this paper. The changes have been the result of legislative changes, new data sources, estimation procedures , changes in knowledge about traffic conditions, and most importantly , growth in demand for the information once reports and data have been used.
