The objective of the Sustainable Transport and Air Quality Project for Mexico is to assist the selected municipalities to: (i) reduce greenhouse gas (GHG) emissions growth rates by fostering long term increases in the use of less energy intensive transport modes; and (ii) induce policy changes in favor of sustainable transport projects. There are five components to the project. The first component of the project is freight management. This component will improve the planning, management, and control of freight transport in Ciudad Juarez. The second component of the project is land use and transport coordination. This component will develop a sustainable approach to address urban mobility patterns and lessen barriers to better integrated planning in Ciudad Juarez and Puebla. The third component of the project is public transport enhancement. This component will provision of technical assistance and training to the selected municipalities to facilitate the improvement of public transport systems, the effectiveness and interconnectivity of those systems with other modes of transport, and induce mode switching away from the use of private cars. The fourth component of the project is non-motorized transport. This component will provision of technical assistance to the selected municipalities to better integrate walking and biking into the municipalities' cultural and planning processes and to create incentives for their use as a viable and safe alternative to traditional motorized transport systems. The fifth component of the project is proiect management. This component will provision of technical assistance and financing for short term technical support staff of the project coordinating unit (PCU) for the supervising and monitoring of the implementation o f the project in the selected municipalities.
