ESTIMATION OF NEW TRAFFIC SIGNALLING TECHNOLOGIES IMPACT ON ENERGY CONSUMPTION
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2010, Vol 34, Issue 34
Abstract
This paper provides results and conclusions of a study regarding the impact of new traffic signaling technologies on energy consumption. The methodology for energy consumption calculation on the products lifecycle is also presented. The new traffic signaling technologies employ nowadays LED-driven traffic lights and new, environmental-friendly technologies for adaptive traffic management systems. The study has been carried on for the whole traffic signaling network in Bucharest, taking into account both older, incandescence lamps light sources, and the new LED signals (only with spot-centered technology). These research activities are part of a wider, EU co-funded research program, concerning the implementation of a real-time traffic information services to mobile users. This multi-national research tries to introduce a new, inter-operative information platform for Multimodal Real Time Traffic and Travel Information (RTTI) services, with the goal to reduce drastically energy consumption in urban areas across the different modes of transport by changing the mobility behavior (modal shift) of the single traffic participant. The paper is concerning on several stages of the energy reduction, starting with an analysis on the production phase, the lifetime in service and the recycling of the traffic light signaling elements and ending with changing the behavior of the drivers. Conclusions and some results obtained in Bucharest are also presented.
