Introduction to the special issue on smart transportation

Bo Xu, Gautam Thakur
2021 Geoinformatica  
They cover ridesharing, human mobility modeling, trajectory computing, routing, and privacy control. GeoInformatica https://doi.  ...  The fundamentals of these computational methods are rooted in space and time, and thus at the core of transportation research.  ...  The first paper, "Optimum Versus Nash-Equilibrium in Taxi Ridesharing", by Luca Foti, Jane Lin, Ouri Wolfson, compares optimum plans and "fair" plans in the context of taxi ridesharing.  ...

Drivers learn city-scale dynamic equilibrium [article]

Ruda Zhang, Roger Ghanem
2021 arXiv   pre-print
We capture driver search strategies in a multi-market oligopoly model, which has a unique Nash equilibrium and is globally asymptotically stable.  ...  Among empirical studies of driver strategy in on-demand services, our work examines the longest period, the most trips, and is the largest for taxi industry.  ...  Farber of Princeton University and Abhishek Nagaraj of UC Berkeley for sharing NYC taxi trip records, and thank Ketan Savla, Sami F.  ...

Reducing Inefficiency in Carbon Auctions with Imperfect Competition

Kira Goldner, Nicole Immorlica, Brendan Lucier, Michael Wagner
2020 Innovations in Theoretical Computer Science  
We describe a subclass of "safe-price" auctions for which the welfare at any Bayes-Nash equilibrium will approximate the welfare under truth-telling behavior.  ...  In particular, we show how to choose a number of licenses and a price floor so that the worst-case welfare, at any equilibrium, is a constant approximation to the best achievable welfare under truth-telling  ...  Another example might be allocating medallions to taxi and rideshare drivers in New York City, where the social cost is congestion.  ...

A many-to-many assignment game and stable outcome algorithm to evaluate collaborative Mobility-as-a-Service platforms [article]

Theodoros P. Pantelidis, Joseph Y. J. Chow, Saeid Rasulkhani
2020 arXiv   pre-print
We adopt a new paradigm for traffic assignment in a MaaS network of multiple operators using the concept of stable matching to allocate costs and determine prices offered by operators corresponding to  ...  Unlike our prior work, the proposed model allows travelers to make multimodal, multi-operator trips, resulting in stable cost allocations between competing network operators to provide MaaS for users.  ...  Earlier research on coexisting operators (see Chow and Sayarshad, 2014 , for a review) consider noncooperative games, including a generalized Nash equilibrium for a duopolistic market of private mass  ...

2021
The modified MDP approach is found to outperform the baseline (i.e., the local hotspot strategy) in terms of both the rate of return and the utilization rate.  ...  ., available vehicles) in the ride-hailing market and severe traffic congestion faced by modern cities, this dissertation aims to improve the efficiency of the sharing economy by building an agent-based  ...  In a Markov game, the solution concept of Nash equilibrium is generally adopted [125] . At a Nash equilibrium, one agent's strategy (i.e., policy) is the best response to other agents' strategy.  ...

Therefore, an outcome can be a Nash equilibrium without being a Pareto optimum. Many times, Nash equilibriums are sup-optimum equilibriums from a Pareto efficiency perspective.  ...  It is important to differentiate a Pareto equilibrium from a Nash equilibrium.  ...  The Decisions Rendered by the Court of Milan At the end of spring 2015, several radio taxi associations and taxi unions of Milan, Genoa, and Turin requested a cease and desist order against Uber from the  ...
