Health-Based Intelligent Transportation Systems

Breadcrumb

Traditionally, Intelligent Transportation Systems (ITS) applications have been developed to address pollutant emissions on a large regional basis, but have not focused on the local health impacts. California is home to many densely populated communities that are adjacent to roadways with heavy traffic. In Los Angeles, more than 30% of the population is living within 50-100 meters of major roads, where pollutant concentrations are often 2-4 times higher than those 100 meters away. The Transportation Systems Research Group is developing novel approaches to reducing the exposure of local communities to high levels of atmospheric particulate matter (PM) through the use of technologies such as pedestrian routing applications.
