Impact Evaluation of the Phases I and II of the Transmilemio Mass Project on the Total Travel Time of the Users of the Traditional Public Transport in Bogotá (Evaluación De Impacto De Las Fases I Y II Del Sistema De Transporte Masivo Transmilenio Sobre El Tiempo Total De Desplazamiento De Los Usuarios Del Transporte Público Tradicional En Bogotá)

Abstract

For decades, public transport has been one of the major problems faced by Bogota city. TransMilenio, the massive transport system, was introduced seeking for an improvement in public transport’s efficiency and productivity, and its main purpose is to achieve a reduction in the passenger’s total travel time. This paper contributes to the study of TransMilenio’s impact over the passenger’s total travel time. Using the “Propensity Score Matching” model and the data available in the Mobility Survey (2005), the total travel time of two groups with similar socioeconomic characteristics but different type of transportation will be compared. Every individual in the sample has access to TransMilenio system and traditional public transport; this generates a common support which makes it possible to evaluate de impact. The main conclusion is that travel time decreases between 11.92 and 13.86 minutes, values that correspond to a reduction of approximately 19% in the passenger’s total travel time. The major impact observed, takes place in the individuals of 1st and 2nd strata, who present a reduction of 24.5%.
