Several researchers have tried to understand the effects of ride-hailing on transportation system performance related metrics such as vehicle miles traveled (VMT) [1], [2], [3]. Most studies are in agreement that Transportation Network Companies increase VMT and decrease public transit ridership [1], [2], [3], [4]. For example, Wu and MacKenzie (2021) used the 2017 National Household Travel Survey (NHTS) along with causal inference to estimate the effect of ride-hailing services on VMT. They concluded that a net 7.8 million daily VMT or 2.8 billion annual VMT were added nationwide due to ride-hailing services at the time of the 2017 NHTS data collection [1]. Other studies have tried to understand the effect of congestion pricing strategies on ride-hailing ridership [1]. For example, Zheng et al. (2023) estimated the effects of ride-hailing congestion pricing policy on ridership in Chicago and concluded that the policy led to a growth in shared trips and a decline in single trips. Some studies have also tried to understand the effects of ride-hailing on transit and other modes of transportation [1], [2], [3].
Current opportunities for future research include: 1) using more updated data (e.g., 2022 NHTS) to assess the effects of ride-hailing on VMT and travel behavior, as the impact of ride-hailing services changes dynamically, and 2) assessing the impact of ride-hailing services in rural areas and less studied regions of the country, which could provide insights for local and state policies.
