Abstract

Any transit process planning includes four basic components performed in sequence: (1) network route design; (2) setting timetables; (3) scheduling vehicles to trips; and (4) assignment of drivers. It is desirable for all components to be planned simultaneously to exploit the system’s capability to the greatest extent and to maximize the systems’s productivity and efficiency. However, this planning process is extremely cumbersome and complex, with the outcome of one fed as an input to the next component. The overview of this planning process is shown in Figure 1 with an emphasis on the three scheduling components to be adressed in this paper. The second component in Figure 1 is aimed to meet the general public transportation demand. The demand varies during the hours of the day, of the week, from one season to another and even from one year to another. This demand reflects the business, industrial, cultural, educational, social and recreational transportation needs of the community. It is the purpose of this component to set appropriate timetables for each transit route to meet the variation in the public demand. Determination of timetables is performed on the basis of passenger counts and must comply with service frequency constraints.
