Spectrum of Public Transit Operations: From Fixed Route to Microtransit

Spectrum of Public Transit Operations: From Fixed Route to Microtransit Overview With advances in emerging technologies, options for operating public transit services have broadened from conventional fixed route service through semi-flexible service to on-demand microtransit. Guidelines for deciding between these services remain limited. This study serves two primary objectives. The first is to provide an…

Traffic Signal Optimization and Coordination in Connected Cities

Overview Traffic Signal Control Challenges Previously, most traffic signal researchers used infrastructure sensors, such as loop detectors or video cameras, as their major source of information on traffic conditions. Traffic control systems mainly relied on manually collected traffic counts and data from these infrastructure sensors. Traffic signal plans were developed based on arrival vehicles adjusted…

Understanding Mobility Patterns and Decision-Making Using an Integrated, Multi-modal Sensing Platform in a Quantified Community

Overview City governments all over the world face challenges understanding mobility patterns within dense urban environments at high spatial and temporal resolution. While such measures are important to provide insights into the functional patterns of a city, novel quantitative methods, derived from ubiquitous mobile connectivity, are needed to provide decision-makers better insights to improve urban…

Integrative Vehicle-Traffic Control in Connected/Automated Cities

Research Objective The researchers plan to investigate the critical issues involved in traffic control at intersections with CAVs in connected/automated cities. In particular, the team aims to achieve the following objectives: Develop methods to deal with mixed traffic flow, i.e. human-driven vehicles mixed with CAVs Develop CAV-based signal coordination methods with multiple signalized intersections Test/validate…

Automated Truck Lanes in Urban Area for Through and Cross Border Traffic

Automated Truck Lanes in Urban Area for Through and Cross Border Traffic Overview Automated Vehicles and Highway Capacity In the current driving system, a significant amount of lateral and longitudinal space between vehicles is required for safety and psychological reasons. The longitudinal separation increases as the speed of the vehicle increases, and larger spaces are…

Dual Rebalancing Strategies for Electric Vehicle Carsharing Operations

Dual Rebalancing Strategies for Electric Vehicle Carsharing Operations Overview Challenges in Vehicle Rebalancing for Car Sharing Services Car sharing is a smart mobility paradigm where a population of users share usage of the vehicles. This can be done through booking vehicles for specific time slots from specific locations that are returned to the same locations…

Development of a Mobile Navigation Smartphone Application for Seniors in Urban Areas

Deliverables The main deliverable for this project was a smartphone navigation app that addresses the specific mobility needs and priorities of seniors, improving their ability to travel around their cities. After the prototype was developed, the researchers recruited seniors to test the app for a few weeks, and then gathered their feedback.  In order to…

Integrated Analytics and Visualization for Multi-Modality Transportation Data

Research Objectives This project studied pedestrian dynamics, which is fundamental to improved urban planning, with applications in transportation network design, safety, and tax revenue. The researchers used tens of millions of images from the region of New York City from 2016 and 2017 and applied computer vision techniques to detect the pedestrians (and cars and…

Sustainability project meeting with Paris Deputy Mayor for Transportation

Sustainability of Urban Consumption Practices

Sustainability of Urban Consumption Practices Overview Urban logistics are becoming increasingly complex: in addition to the heterogeneity of goods transported and of the means of transportation, urban logistics encompass diverse multiple stakeholders (local authorities, transporters, retailers). The sustainability of goods transported and personal mobility will be a major challenge for both public and private sectors.…
