Abstract
In many cities of developing countries, buses are the backbone of public transport. However, most of them currently operate in mixed and heavily loaded traffic flow. Illustrative examples of these cities are Hanoi and Ho Chi Minh City, which are called motorcycle dependent cities (MDCs). A lack of priority lanes for buses on urban roadways is one of the main causes leading to the poor quality of bus services and the rapid growth of individual motorised traffic in these cities. Consequently, MDCs are facing critical transport problems in terms of traffic congestion, environmental pollution, traffic accidents, and economic loss. In order to prioritise buses under heavily loaded traffic conditions on urban roadways of MDCs, this paper introduces a new type of bus lanes, namely partial dynamic bus lanes.
