A Green Light for Urban Efficiency

This article describes how intelligent intersection control systems have a growing role to play in making urban traffic more efficient. The idea of every traffic light turning green as you approach it has long been a dream for many urban drivers and none more so than those driving heavy goods vehicles (HGVs), which are slow and difficult to bring to a halt and then accelerate back to normal travel speed. That dream has become a reality for some drivers in a small number of cities around Europe over the last few years, thanks to the Freilot project. The European Union (EU) co-funded Freilot (Urban Freight Energy Efficiency Pilot) scheme was a cooperative mobility services project that began in October 2010 and tested a range of intelligent systems including energy-efficient intersection control, eco-driving support, loading bay advance booking, and in-vehicle speed and acceleration limiters, that were all designed to help boost safety and efficiency while reducing fuel consumption and vehicle emissions. The pilot was conducted in four European cities – Helmond (The Netherlands), Bilbao (Spain), Lyon (France) and Krakow (Poland). The trial was a striking success, particularly in terms of energy-efficient intersection control. Ensuring that emergency vehicles and heavy trucks could pass through junctions more often on a green light boosted travel times and cut fuel consumption, as well as reduced the kind of collisions that so often occur at intersections.
