An estimation of operating speed increase by tram signal priority

Due to the excessive private car usage, the City of Zagreb is faced with motorization rate increase in the past few decades, constantly reducing the operating speed in tram network to its lowest values at the present, rendering public transport unattractive. Besides the partial integration within the road network and therefore interactions with motor vehicles, an additional reason for such values is very poor signal priority for trams at intersections. The previous research on tram signal priority has predicted significant operating speed increase for the network if the technology was implemented only partially, so this paper presents a simple methodology based on vehicle running times for estimating time savings and operating speed increase. The results in the paper estimate if signal priority could increase the operating speed to satisfactory levels by European standards, for shifting users from private cars, and making transport system in the city more sustainable in terms of finances, space and environment.
