Abstract

A Short-term Management Strategy for Improving Transit Network Efficiency

Highlights

  • Public transit system, a basic part of the transportation network in urban areas, benefit society by providing mobility to people in shared vehicles

  • Quasi-Gradient Fleet Assignment (QGFA) starts with the current fleet distribution and improves the total system cost by 12%, just by reassigning the vehicles to the bus network

  • Total walking time has dropped from almost 25 h to near 7 hrs, which shows a significant increase in the bus network efficiency

Summary

Introduction

A basic part of the transportation network in urban areas, benefit society by providing mobility to people in shared vehicles. Since two essential parts of the design process of an urban bus network are determining the bus routes and setting the vehicle frequencies, both bus routes and the associated frequencies might be examined to improve current operating conditions. Both fleet assignment and route selection should be modeled simultaneously. Route selection should be considered a long term problem. System operators should not change the bus routes very often, even if it benefits total system revenue in the short term. A reliable fleet assignment algorithm could be a helpful short term management tool for the transit network operators. The main objective of this paper is to propose a simple approach to effectively manage the fleet in a bus network
