When vehicles are idling in heavy or standstill traffic congestion, the resulting emission pollutants impact air quality significantly. El Paso region border ports of entry are of particular concern due to the north- and southbound commercial and passenger vehicle queues and long wait times at inspection stations. TTI researchers recently completed a computer modeling effort to examine the emissions impacts at the Ysleta-Zaragoza port of entry at El Paso/Cuidad Juarez which provided insights into how various combinations of reduction in wait time and open inspection booths can affect emissions differently for passenger and commercial vehicles. | Read the Featured Project Page
