Abstract

ABSTRACT We propose a model and solution method to a simultaneous route design and frequency setting problem on a main corridor from one of the Bus Rapid Transit (BRT) Systems of Colombia. The proposed model considers objectives of users and operators in a combinatorial multi-objective optimization framework and takes into account real constraints on the operation of some Colombian BRT systems not found in previous models. The problem is solved heuristically by a Genetic Algorithm which is tailored from an existing work, to consider specific characteristics of the real scenario. The methodology is validated with current data from one of the most important bus corridors in a Colombian BRT system. The results obtained improve the current solutions for this corridor.

Highlights

Public transport substantially determines the quality of life of the inhabitants of urban areas
We proposed a mathematical model and a solution method to the problem of determining simultaneously routes and frequencies for a main corridor of SITM in Colombian cities
Both problem formulation and solution method are adapted from the work of (Szeto & Wu, 2011), proposed originally for the city of Tin Shui Wai, Hong Kong

Summary

Introduction

Public transport substantially determines the quality of life of the inhabitants of urban areas. Due to the high costs of implementing rapid transit systems based on rails, developing countries (especially in Latin America), as well as industrialized nations have been adopting Bus Rapid Transit (BRT) systems, which require less investment due to some factors as the use of more economical technologies (Hensher & Golob, 2008). Bus Rapid Transit denotes a high-quality bus-based transit system that delivers fast, comfortable, and cost-effective services at metro-level capacities (Levinson et al, 2002). A BRT corridor is a section of road or contiguous roads served by one or multiple bus routes with a required minimum length of kilometers dedicated to bus lanes. There are some essential features that define a BRT as Dedicated Right-of-Way, Busway Alignment, Off-board Fare Collection and Platform-level Boarding
