Abstract

One of the operational problems for urban transit, especially with buses, occurs in a situation in which vehicles need to park at route-departure/controlled/holding stops located on-street; however, because of a lack of parking spaces, the buses block the traffic lane adjacent to the parking bay/lane. Such operational scenarios are commonly observed at school dismissal times. One way to solve the problem is to construct more parking spaces at these conflict points; however, this is a costly and time-consuming solution. This work presents a scheduled-based design solution to this problem in which lane-blocked situations are caused at route-departure points. That is, eliminating or reducing the impact of lane-blocked situations through the use of shifting departure times and/or inserting DH trips in timetables.

A public transport (transit) vehicle makes a chain of trips called a “vehicle schedule” in each daily activity. The trips in this schedule may be performed in a sequence of time intervals, and usually there is a need for a wait (idle time) until the next trip's departure time. Every trip on the chain is characterized by a starting point and an ending point, a departure time and an arrival time. The situation in which the vehicle is parking and waiting for its next trip is called "operational parking". Often the operational parking, in urban areas, demands more space than what it is available, and the transit vehicle is in conflict as to whether to park in parallel to other vehicles and disturb the traffic or to circle around. If circling around, the driver has no rest time and hence may face an overload of pressure. Disturbing the traffic, on the other hand, may create either unnecessary traffic congestion or an unsafe traffic situation, or both. The adverse affect of a limited operational parking space is apparent, and this research is aimed at improving similar situations. The situation in which the number of demanded operational parking spaces exceeds the available space is a harmful circumstance from the perspective of the transit company, the transit drivers, the transit users, the local authority and other drivers that use the same problematic road segment. The research concentrates on solving the problem of minimizing the situations in which the operational parking space exceeds the available space.
