Nashville's signal optimisation programme produced a stunning return on investment. Are those results exceptional? Could similar results be replicated in cities across the US and indeed the world? ITS International spoke to Chris Rhodes, P.E. of Kimley-Horn and Associates, project leader for the Nashville signal optimisation programme. "You have to bear in mind that with signal optimisation programmes you don't see, for instance, physical construction or new pieces of equipment on the roadside that someone

A new vehicle routeing initiative has arisen to help improve emergency response and relief following natural disasters in Japan. David Crawford reports Japan’s national ITS group ITS Japan and the country’s leading automotives have agreed on a new combined approach to the organisation of traffic management and emergency response in the wake of major natural disasters. A new, robust traffic information platform using probe data obtained from vehicles to support traffic flow will build on the shared experienc

Road markings are among the most cost-effective solutions to make roads safer. A recent study carried out for the American Glass Bead Manufacturer’s Association quantifies by just how much Despite only making up 23% of the US mileage, fatalities on America’s rural two-lane highways made up 57% of all traffic fatalities in 2009 — resulting in more than $77Bn in losses for that year alone. Moreover, a rural motorist is 2.7 times more likely to be involved in a fatal crash per mile travelled than their urban

A programme of road safety education and enforcement in the State of Jalisco in Mexico has reduced speed related fatalities by 40% in nine months Speed enforcement equipment will appear in greater number and visibility around the city of Guadalajara over coming months, as the Mexican State of Jalisco expands its road safety campaign. This comes hot on the heels of an initial programme of traffic speed education and enforcement in Guadalajara, which has yielded remarkable results, reducing speed related fata

Need for a temporary communication fix during a construction project has led to rapid deployment of a permanent but simplistic wireless broadband network in Chandler, Arizona When a major construction project was expected to disrupt highway communications in the city of Chandler, Arizona, the city’s engineers went looking for a simple solution. They needed a way of maintaining data connections with three consecutive intersections along Arizona Avenue in Chandler while construction necessitated the severin

Convergence of electron-powered vehicles with connected vehicle technologies could mean that only a few decades from now the idea of owning a vehicle will be entirely alien to the road user. By Technolution chief scientist Dave Marples with Jason Barnes Even when taken individually, many of the developments going on and around vehiclebased mobility will bring about major changes in transportation. Taken collectively, the transformations we might expect are nothing short of profound. Enumeration of the influ
