ENVIRONMENTAL TRAFFIC CONTROL

This paper describes the APOLLON pilot project in Athens which is evaluating air pollution limiting traffic control strategies, implemented in advance of pollution episodes. APOLLON is being carried out as part of the QUARTET project which involves four European cities: Athens, Birmingham, Stuttgart and Turin. It is part of POLIS, a European initiative to expand IVHS awareness, to facilitate the exchange of ideas and to develop common future plans. This paper outlines the essential modules of the APOLLON system. These comprise environmental monitoring (for on-line verification of pollution levels), continuous monitoring of traffic flows, short-term meteorological forecasts, air quality models to estimate expected traffic pollution levels (carbon monoxide, hydrocarbons and nitrogen oxides), an off-line tool to determine the effects of alternative control strategies, and IVHS technology to implement the control strategies.
