Assessing the VMT effect of ridesourcing services in the US
Transportation Research Part D: Transport and Environment, 2021Abstract The net effect of ridesourcing (RS) services on vehicle miles traveled (VMT) is ambiguous. With 2017 US National Household Travel Survey data, this study measures and compares the heterogeneous VMT effects of RS across population groups with various levels of household vehicle access and RS usage.

Travel and Energy Implications of Ridesourcing Service in Austin, Texas
Transportation Research, Part D: Transport and Environment, 2019 Abstract This paper identifies major aspects of ridesourcing services provided by Transportation Network Companies (TNCs) which influence vehicles miles traveled (VMT) and energy use. Using detailed data on approximately 1.5 million individual rides provided by RideAustin in Austin Texas, we quantify the additional miles TNC drivers travel: before ...

Has ridesourcing reduced haze? An analysis using the Didi app
Environmental Science and Pollution Research, 2021Environmental degradation, often evidenced by haze, has not only increased the cost of China's economic development, but its unfair distribution among regional development, social hierarchy, and generations has also reduced quality of life. Hence, this study uses cross-sectional data from Didi, a Chinese ridesourcing service company, from 2017 to study

A distributed algorithm for operating large-scale ridesourcing systems
Transportation Research Part E: Logistics and Transportation Review, 2021Abstract With ridesourcing services gaining popularity in the past few years, there has been growing interest in algorithms that could enable real-time operation of these systems. As ridesourcing systems rely on independent entities to build the supply and demand sides of the market, they have been shown to operate more successfully in metropolitan ...

Subsidized ridesourcing for the first/last mile
2019Many transit agencies partner with ridesourcing companies to offer subsidized first/last mile services. Ridership, however, has been low in many cases. Complementing popular operational explanations for low ridership, we explore two conceptual ones: using ridesourcing for the first/last mile adds an additional transfer and costs to the overall transit ...

An Efficient Auction with Variable Reserve Prices for Ridesourcing
2018Ridesourcing refers to the service that matches passengers who need a car to personal drivers. In this work, we study an auction model for ridesourcing that sells multiple items to unit-demand single-parameter agents with variable reserve price constraints. In this model, there is an externally imposed reserve price set for every item, and the price is

A Framework for Understanding the Impacts of Ridesourcing on Transportation
2017The transportation sector is currently experiencing a monumental disruption with the introduction and evolution of technology and transportation services such as bikesharing, carsharing, on-demand ridesourcing, and microtransit. As these new layers of technology-based transportation options begin to flourish, it is important to understand how they ...

Dynamic Congestion Pricing for Ridesourcing Traffic: a Simulation Optimization Approach
2019 Winter Simulation Conference (WSC), 2019Despite the documented benefits of ridesourcing services, recent studies show that they can slow down traffic in the densest cities significantly. To implement congestion pricing policies upon those vehicles, regulators need to estimate the degree of congestion effect.
