Optimizing Freight Routing: PSR Researchers Investigate Freight Coordination with Traffic Simulators

Wednesday, April 13, 2022

Freight transport systems deliver products across the country. However, inefficient shipping methods, including sub-optimal routing, can cause unnecessary delays and contribute to congestion. In 2016, congestion from trucking, the most common method of moving freight, cost the US economy $74.5 billion by delaying traffic a total of 1.2 billion hours. There are also environmental costs. Trucking contributes 68% of all GHG emissions sourced from freight movement.   To optimize trucking ...

Mapping Vehicle Air Pollution Based on Sociodemographic Factors

Thursday, March 10, 2022

Air pollution is an environmental problem that affects us all but does not affect us equally. Vehicle related air pollution, including small particulate matter (PM2.5) is more concentrated along more heavily trafficked routes, many of which traverse lower income minority neighborhoods. Reducing these disproportionate impacts requires intentional and environmentally conscious interventions by city planners and policymakers.   The historical pattern of highway building has placed major ...

PSR Researchers Develop Models to Optimize Sidekick Freight Deliveries

Thursday, March 10, 2022

From drones that transport blood samples to cube robots that dispatch groceries, automated and autonomous small vehicles are streamlining delivery services. In efforts to further optimize vehicle-based transport, sidekick routing has emerged as a logistical framework in which a base vehicle such as a truck or van hosts several ‘sidekicks’ – smaller ‘helpers’ like unmanned aerial vehicles (UAVs) or autonomous ground vehicles (AGVs). These sidekicks move between picking ...

Environmental Justice in Southeast Los Angeles: PSR Researcher Address Pollution and Mobility Issues

Monday, December 6, 2021

Environmental justice is concerned with eliminating the disproportionate impacts of environmental damage on low-income communities and ensuring residents have a say about the activities that affect their environment and health. Research in environmental justice means uncovering, analyzing, and proposing solutions to the higher rates of environmental burdens in these communities. These burdens include excessive exposure to toxic air pollutants, hazardous materials, and water pollution. The project ...

PSR Researcher Dan Wei Analyzes the Socioeconomic Dimensions of Transportation Network Disruptions and Discusses Resilience Tactics

Thursday, April 29, 2021

The year 2020 has accentuated the importance of preparation and response to disaster and disruption. A global pandemic and the recent Suez Canal blockage in 2021 come with a lesson—unexpected disruptions can and will happen, and it is advantageous to prepare for disturbances ahead of time instead of improvising during precarious moments. Although it is impossible to predict precisely what will happen in the future, it is possible to prepare for general network disruptions through insights ...

PSR Congress 2021 - A Remote but Rewarding Experience

Wednesday, April 28, 2021

The Fourth Annual Pacific Southwest Region University Transportation Center (PSR) Congress took place virtually on April 12th and 13th and was filled with transportation information to inspire, motivate, and encourage imaginative problem-solving skills for the transportation research community. There were many subjects discussed in the main room and side rooms during the on-line conference, covering topics from freight delivery to the implications of sea level rise on transportation systems. The ...

PSR Researcher Michael Zhang Evaluates the Use of Variable Speed Limits to Mitigate Carbon Footprint

Friday, January 29, 2021

The goal of reducing greenhouse gas emissions and fuel consumption stemming from vehicle usage calls for creative solutions in unexpected areas. Michael Zhang, Professor in the Department of Civil and Environmental Engineering at University of California, Davis, along with Graduate Researchers Hang Gao and Shenyang Chen, examined the potential of using variable speed limits (VSL) to lessen environmental damage. Variable speed limits allow the speed limit to vary depending on traffic conditions. ...

UCLA Professor Loukaitou-Sideris Examines How to Combat Sexual Harassment on the "Public Transit Journey"

Thursday, December 3, 2020

A commonly cited concern found among transit riders is the danger of sexual harassment. Sexual harassment is a common occurrence in everyday transit environments (e.g., train stations, train wagons, buses, and bus stops). Each step of the journey until the transit riders reach their destination is a potentially hazardous situation. UCLA Distinguished Professor of Urban Planning Anastasia Loukaitou-Sideris and ...
