Optimal timings for city stoplights reduce drive time
Anyone who has ever driven a city street and been frustrated by having to stop again and again for red lights has probably thought that there must be a better way. Now, researchers at MIT have developed a ...
Google self-driving car coming around the corner
A white Lexus cruised along a road near the Google campus, braking for pedestrians and scooting over in its lane to give bicyclists ample space.
At stoplights, pedestrians experience longer delays while cars are given priority
How long is too long to wait for the light to change? At stoplights, pedestrians often experience longer delays while cars are given priority.
Chinese city blanketed in heavy pollution
Choking clouds of pollution blanketed a Chinese city famed for its annual ice festival Monday, reports said, cutting visibility to 10 metres (33 feet) and underscoring the nation's environmental challenges.
Ford tests high-tech 'brake light' that warns other drivers even from afar
Ford Motor Company participated in a special test of a high-tech early warning "brake light" that can warn drivers following behind even if they are around a bend or behind other traffic.
Progressive traffic signal systems save time and fuel
In cities, the uniform and low speed levels simplify the setup of synchronized traffic signals. Outside urban areas this is a bigger challenge: The travel speeds vary more and the distances between the traffic ...
World cities improving energy efficiency, report says
