Cost Estimating Model for Mode Choice between Light Rail and Bus Rapid Transit Systems

Abstract

A cost estimating model is developed for light rail transit (LRT) and bus rapid transit (BRT) systems to better aid transportation planners and decision makers in the selection process. In evaluating transit systems, cost estimating has always been a major consideration. Without an applicable cost estimating model or methodology, the decision on the choice between LRT and BRT would cause significant controversy and difficulty in the early corridor planning stage. The model developed in this paper can be applied to estimate costs and compare the LRT and BRT systems that operate on various right-of-way categories, alignment configurations, and different given transit demand volumes. An example and comparative analyses illustrate how the model can be applied in real-world situations.
