David Crawford reviews a new approach to traffic smoothing. A key objective for the Californian city of Bakersfield’s upgraded traffic operations centre (TOC), which opened in June 2014, is to help improve living conditions in a region with one of the worst air quality problems in the US. The TOC is speeding up the smoothing of traffic flows by delivering faster and better-informed traffic signal retiming and synchronisation.

Colin Sowman catches up with the latest moves in the 5.9GHz exclusivity debate. The Wi-Fi Innovation Act, recently introduced to both the US Senate and its House of Representatives, moves into a new phase in the debate over the exclusive right of the 5.9GHz band for Vehicle to Vehicle (V2V) communications. If the Act comes into law, it would require the Federal Communications Commission (FCC) to conduct tests across the whole 5GHz band to determine if the spectrum can be shared without interfering with curr

Victoria Banks and Neville Stanton [1] of Southampton University’s Transportation Research Group examine the real impact of creeping driver automation. Safety research suggests that 90% of accidents are thought to be a result of driver inattentiveness to unpredictable or incomplete information and the vision is that highly automated vehicles will lead to accident-free driving in the future.

David Crawford investigates a promising development to counter the problem of fog in the Gulf States. Despite being a largely desert area with low rainfall, fog is a major driving hazard in countries on the Arabian peninsula, such as the UAE. The fog is the result of moist air moving across from the neighbouring Gulf during the afternoon and evening, and experiencing radiation cooling at night.

ASECAP debated the impact of the financial crises on Europe’s tolling companies and considered the future in diverse economies. Colin Sowman picks some of the highlights. This year ASECAP (Association Europeenne des Concessionnaires d’Autoroutes et d’Ouvrages a’ Peage, with members in 21 countries managing 46,000km of roadway) held its annual Study & Information Days in Athens, Greece – one of the country hardest hit by recent economic problems. While the theme of the conference, Ensuring Sustainability in

New regulations are set to standardise the process of awarding concessions across the European Union. In the wake of several inconsistent judgements at the European Court of Justice, the European Commission has approved new legislation that defines a concession. The basic demarcation from a public contract remains the same in that concessions include the right to exploit the work or services provided instead of payment.
