چکیده

As a Mayor, one of your greatest challenges is to plan and invest wisely in infrastructure for sustainable urban transport.

Those cities with transport modes in an integrated system are more likely to evolve and prosper as centers for trade, commerce, industry, education, tourism and services. It is common that cities ranking at the top of surveys measuring urban quality of life have high quality urban transport systems that prioritize public transport and non motorized modes.
