• Abstract: Current transit suffers from an evident inequity: the level of service of transit in suburbs is much less satisfying than in city centers. As a consequence, private cars are still the dominant transportation mode for suburban people, which results in congestion and pollution. To achieve sustainability goals and reduce car-dependency, transit should be (re)designed around equity. To this aim, it is necessary to (i) quantify the "level of equity" of the transit system and (ii) provide an indicator that scores the transit lines that contribute the most to keep transit equitable. This indicator could suggest on which lines the transit operator must invest to increase the service level (frequency or coverage) in order to reduce inequity in the system. To the best of our knowledge, this paper is the first to tackle (ii). To this aim, we propose efficient scoring methods that rely solely on open data, which allows us to perform the analysis on multiple cities (7 in this paper). Our method can be used to guide large-scale iterative optimization algorithms to improve accessibility equity.

• Fair collaborative vehicle routing: A deep multi-agent reinforcement learning approach [49.00137468773683]
  Collaborative vehicle routing occurs when carriers collaborate through sharing their transportation requests and performing transportation requests on behalf of each other. Traditional game theoretic solution concepts are expensive to calculate as the characteristic function scales exponentially with the number of agents. We propose to model this problem as a coalitional bargaining game solved using deep multi-agent reinforcement learning.

• Short Run Transit Route Planning Decision Support System Using a Deep Learning-Based Weighted Graph [0.0]
  We propose a novel deep learning-based methodology for a decision support system that enables public transport planners to identify short-term route improvements rapidly. By seamlessly adjusting specific sections of routes between two stops during specific times of the day, our method effectively reduces times and enhances PT services. Using self-supervision, we train a deep learning model for predicting lateness values for road segments. These lateness values are then utilized as edge weights in the transportation graph, enabling efficient path searching.

  Traffic Signal Control (TSC) aims to reduce the average travel time of vehicles in a road network. Most prior TSC methods leverage deep reinforcement learning to search for a control policy. We propose DenseLight, a novel RL-based TSC method that employs an unbiased reward function to provide dense feedback on policy effectiveness.

  The rise in urbanization throughout the United States (US) in recent years has required urban planners and transportation engineers to have greater consideration for the transportation services available to residents of a metropolitan region. These improvements can be achieved by identifying and understanding the factors that influence urban public transit demand. Common factors that can influence urban public transit demand can be internal and/or external factors.

• Frustratingly Easy Transferability Estimation [64.42879325144439]
  We propose a simple, efficient, and effective transferability measure named TransRate. TransRate measures the transferability as the mutual information between the features of target examples extracted by a pre-trained model and labels of them. Despite its extraordinary simplicity in 10 lines of codes, TransRate performs remarkably well in extensive evaluations on 22 pre-trained models and 16 downstream tasks.

We then introduce a general route search algorithm coupled with an efficient station binding method for efficient route candidate generation. Experiments on two real-world data sets demonstrate the advantages of Polestar in terms of both efficiency and effectiveness.
