Efficiency measurement of bus routes in Hanoi city: An application of data envelopment analysis (DEA)

Efficiency analysis of bus transit at the route level is critical to understand the existing performance of individual routes within a bus system and identify operational problems as well as effectively optimise their performance. This article applies the Data Envelopment Analysis (DEA) model to examine the performance of 38 bus routes in Hanoi, Vietnam. The results indicated the best and the inefficient bus routes within the given sample and identified the internal sources of inefficiency, including: number of stops and vehicles. The findings provide bus agencies in the case study with additional and useful information for decision making.
