台北市公車專用車道實施績效評估

Abstract

Installing special bus lanes can save the travel time, ameliorate the operation environment, and promote the use of mass transportation. Furthermore, through the special right of way, the traffic flow is improved and simplified. Therefore, the level of service will be enhanced. At the same time of such installation, traffic congestion will be relievedThis research is divided into two parts to evaluate the performance. First part is to evaluate the performance of the operation items of roads. We know that special bus lanes in Taipei improve the traffic condition, because vehicles with the Same characters travel on the same lane car make the speed almost identically. Beside increasing the speed of all kinds of modals and the level of service, traffic accident rate is lowered. The overall condition of traffic has improved. Second part is to evaluate the perception of passengers. We know from early study that the supporting rate of special bus lanes by bus passengers, car drivers, motorcycle riders, stores on the roadside, and companies is between 70% to 90%. The satisfaction rate is between 60% to 75%, for the other group such as the stores and companies since parking at the roadside and 1oading, and unloading goods have became not as convenient as before. Together with the other indexes, the special bus lanes prove to bring positive result to all users even though the level of impact varies. From the whole society's point of view, the special bus lanes in Taipei are very successful and supported by most people.The network created by eight special bus lanes in Taipei has been in operation for ten months. With efficiency on the rise, the support by people will increase. Under this situation, the elaboration and expansion of bus lanes network are inevitable. In this period, the most important thing is to learn from past experience, and keep the good points to develop a better transportation system.
