According to the World Bank Group, in the paper "Public Transport service optimization and system integration"

The lack of integration in the public transportation system has long been a major complaint in passenger satisfaction surveys. To reach a destination, for example, a rider is often forced to take multiple routes, each with different schedules and transfer stations but without coordination on passenger information. As a result, the rider may have to take a long walk to make transfers and pay multiple fares. It also creates overlapping services and discourages ridership, according to the paper.

 

“Public transport runs efficiently when it operates as a seamless, integrated system. This is particularly important in fast-urbanizing economies such as China and India, where public transport must increasingly compete with privately-owned cars,” said Ke Fang, a lead urban transport specialist of the World Bank and co-author of the paper.
