Abstract:
One of the crucial aspects in the vehicles exhaust emission is, often the long duration of vehicles stop phase before the rail-road crossing before the rail vehicle passes through. During the road vehicle stop, the combustion engine in most cases operates in idling conditions. Some drivers turns off the combustion engines during mentioned stop time. In modern vehicles there is also the start&stop system implemented, which automatically stops and starts the combustion engine. Combustion engine idling phase is related to inefficient operation, where after switching the engine off, the catalytic converter could cool down, which could result in increased emission of harmful exhaust compounds after start of the engine. The analysis made in reference to the Poznan agglomeration, shows many places where alternative routes can be determined with regard to the necessity of reaching the destination, when there is a road-rail crossing on the way. The purpose of the performed work was first of a
ll to determine the potential of reducing fuel consumption and exhaust emission by cars as a result of the improvement in the transport system efficiency. The improvement of transport system efficiency could be assumed as a trip duration reduction, when the driver could receive the information about the actual state of the rail-road infrastructure.
