Enhancing private transportation: The positive spillovers from Santiago’s subway expansion
In Latin America, where traffic congestion is severe, governments often expand subway systems to reduce traffic. Evaluation of the efficacy of these investments poses challenges, notably due to the scarcity of real-time data. This study uses Uber Movement data, which provides detailed information on daily travel times, to examine the effects of subway expansions on car transportation in Santiago, Chile. We find that introducing a new subway line reduces car travel times by an average of 1.5% (0.309 min), with a greater reduction of up to 0.571 min during peak traffic hours.
期刊介绍:
Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
