- *Abstract
-
Background:
Traffic signals at traditional intersections impede traffic flow thereby increasing harmful emissions, travel time and fuel/energy consumption. With over 250 million vehicles on the road, many municipalities are seeking novel ways to improve the current intersection design to be eco-friendly and safe for both drivers and pedestrians, while remaining efficient.
Brief Description:
Unconventional Arterial Intersection Design (UAID) is the science and art of designing traffic intersections to improve mobility and safety. UCR researchers have designed the first real continuous flow intersection. This novel design allows drivers to maintain their speed throughout the intersection and get from point A to B without stopping. As a result, it increases traffic capacity and land utilization while decreasing travel time and the likelihood of accidents. They have also implemented a novel pedestrian passageway that protects pedestrians from vehicles and direct exhaust emissions.
