Driving patterns reducing pollutant emission at traffic lights

Abstract

The reduction of vehicular pollutant emissions is pursuit by different actors, from local traffic managers to vehicle manufacturers. One promising attempt are in-vehicle solutions that advice the driver to use a most environment-friendly speed and acceleration over time. One of them is GLOSA, Green Light Optimal Speed Advisory, which is based on vehicular communications. While mainly targeting on increasing comfort and traffic efficiency, GLOSA is assumed to decrease the amount of used fuel and emitted pollutants as well. This report distinguishes driving modes that differ in emission levels, shows optimal speeds and accelerations for these modes, and benchmarks existing models for approaching an intersection, including two new ones that lead to the lowest emissions.
