The shift toward electric vehicles (EVs) involves addressing both environmental sustainability and social equity concerns. It underscores the importance of inclusive approaches to ensure fair access to EV technology. As EVs gain traction as a sustainable transportation strategy, it is critical to address disparities in charging infrastructure, vehicle affordability, and environmental justice. There is a need to incorporate EVs into social equity frameworks that include innovative policies, community involvement, and targeted investments in underserved areas. A comprehensive approach is...

Vehicle-infrastructure cooperation via the Connected Vehicle initiative is a promising mobile data source for improving real-time traffic management applications such as adaptive signal control. This paper focuses on developing estimation methods with the use of Connected Vehicle data for several measures of effectiveness (e.g., queue length, average speed, number of stops), essential for determining traffic conditions on urban signalized arterials for real-time applications. This research systematically determines minimum penetration rates that allow accurate estimates for a wide range of...

This guide presents a rational approach for identifying traffic control strategies for mitigating oversaturated conditions at signalized intersections. The guide discusses the following components of the rational approach: diagnosis of the type and causes of the oversaturated condition; identification of appropriate operational objective(s) based on the observed condition(s); identification of appropriate strategies to address the situation; and identification of any necessary infrastructure, equipment, or software requirements for each strategy. The intended audience for this guide is a...

While transportation funding can be collected in a variety of direct (e.g., fares, tolls, and gas taxes) or indirect (e.g., property and sales tax) ways, dynamic demand responsive pricing not only collects revenue but also incentivizes travelers to avoid peak-demand periods, thus utilizing infrastructure capacity more efficiently. Unfortunately, the demand response to price changes, called the price elasticity of demand, is generally greater for longer-term travel planning (e.g., air and rail travel) than it is for more atomized short-term planning (e.g., highway tolls and transit fares)....
