Attention-Based Data Analytic Models For Traffic Flow Predictions, Kaushal Kumar, Yupeng Wei

Mineta Transportation Institute

Traffic congestion causes Americans to lose millions of hours and dollars each year. In fact, 1.9 billion gallons of fuel are wasted each year due to traffic congestion, and each hour stuck in traffic costs about $21 in wasted time and fuel. The traffic congestion can be caused by various factors, such as bottlenecks, traffic incidents, bad weather, work zones, poor traffic signal timing, and special events. One key step to addressing traffic congestion and identifying its root cause is an accurate prediction of traffic flow. Accurate traffic flow prediction is also important for the successful deployment of smart transportation …

Incorporating Public Health Into Transportation Decision Making, Bruce Appleyard, Tim Garrett

Mineta Transportation Institute

Investments in transportation have the potential to significantly affect public health outcomes. Decisions to build highways, transit, or bikeways, for example, influence how residents and visitors move around a metropolitan area.

Transportation Utility Fee To Fund Transit In California, Shishir Mathur, Ralph Robinson

Mineta Transportation Institute

Public transit is a key tool to reduce greenhouse gas (GHG) emissions to combat climate change; improve safety for pedestrians, cyclists, and drivers; and expand accessibility and mobility for all. However, we can only realize this potential by making sufficient investments to provide transit service levels that attract and retain greater ridership. To help with this needed investment, a handful of local governments have turned to transportation utility fees (TUFs), primarily collected as a monthly charge on customers' utility bills or property tax bills. While more widely used to support street maintenance, this study identifies six case studies where TUF …

Local return refers to the component of county LOST measures that provides funding directly to municipalities in the county to be used to meet local needs. Local return has become a fixture in LOSTs; 58 LOST measures placed on the ballot in California (as of 2019) that have included local return in their expenditure plan have an average of 35% of revenues dedicated to local return. Local return provisions in the ballot measures often …

Harmonizing Climate Change Mitigation And Adaptation In Transportation And Land-Use Planning In California Cities, Serena E. Alexander, Asha Weinstein Agrawal, Ashley M. Hooper, Michael R. Boswell

Mineta Transportation Institute

Abstract: Recent extreme weather events in California—wildfires, drought, and flooding—make abundantly clear the need to plan effective responses to both the causes and the consequences of climate change. A central challenge for climate planning efforts has been identifying transportation and land-use (TLU) strategies that simultaneously reduce greenhouse gas emissions (“mitigation”) and adapt communities so that they will be less affected by the adverse impacts of climate change (“adaptation”). Sets of policies that collectively address both mitigation and adaptation are known as “integrated actions.” This study explores municipal climate planning in California to determine whether cities incorporate integrated actions into their …

Land Use And Transportation Alternatives: Constraint Or Expansion Of Household Choice, Mti Report 01-19, Jonathan Levine

Mineta Transportation Institute

Transportation and land use research that considers such alternatives as New Urbanist development, jobs-housing balance, transit villages, or “smart growth” most typically tests the capacity of such physical forms to reduce vehicle miles traveled (VMT) or bring about other desired outcomes in the modification of travel behavior. Establishing such causality is broadly seen as a precondition for the urban planning interventions that are presumed to be necessary to bring these forms about. But such a view neglects the extent to which current interventions—notably zoning and transportation regulations—tend to preclude the development of such innovations in areas of high accessibility where …

Implementation Of Zurich’S Transit Priority Program, Mti Report 01-13, Andrew Butler Nash
