The Context

Querétaro, a historic city in the center of Mexico named a United Nations World Heritage Site, faces the predicament of fast-growing medium-sized cities—a need to upgrade its public transportation system to control rapidly rising motorization rates and high congestion levels.

EMBARQ worked with the city to quantify the emissions from the existing bus system and showed that introducing a BRT corridor and improving the efficiency of the bus network could yield extensive emissions reductions. Introducing alternative fuels and vehicle and emission control technologies yielded little additional reductions.
