Research Highlights

This study was conducted to measure Indiana’s highway user cost responsibilities, revenue contributions, and equity for cars, trucks and buses using Indiana highways. This study comes at a particularly important time as the nation is transitioning to alternative fuels that do not collect tax revenue

Emerging C-V2X (Cellular vehicle to everything) technology uses cellular networks to enable communication between vehicles and infrastructure.

Approximately 2300 signalized intersections (Figure 1) were analyzed using Purdue Connected Vehicle Signal Analytics to screen all 8 movements, to determine if all 8 movements were operating satisfactorily (Figure 2a), or if any movement at an intersection had a split failures (Figure 2b). For

Milling can be defined as a process of removing the pavement surface, and other layers, using drum-mounted carbide steel cutting bits attached to a milling machine. Pavement milling may alter the surface texture of the remaining structure, creating differences from the original surface which can

At the JTRP Executive Committee Meeting on September 20, 2024, an update on the Dynamic Wireless Power Transfer Project was provided by the Advancing Sustainability through Powered Infrastructure for Roadway Electrification (ASPIRE) Research Team consisting of Nadia Gkritza, John Haddock, Steve Pekarek, Dionysios Aliprantis , and Aaron Brovont. Partners and stakeholders from Venture Logistics, Cummins, Subaru, and Purdue Engineering

Agency roadside cameras play a critical role in traffic incident management by helping dispatchers quickly identify the precise location of incidents when receiving reports from motorists with varying levels of spatial accuracy. During real-time incident dispatching, reducing the time it takes to identify the most relevant cameras and setting their view on the incident is an important opportunity to improve incident management dispatch times.

Researchers from Purdue's Joint Transportation Research Program (JTRP) and across the globe are employing data analytics, connected technologies and other innovations to help make intersections safer and more efficient.

In order to advance INDOT's friction testing program to cover the entire highway system, this study addressed the following emerging challenges:

Highway construction and maintenance workzones often have a number of injuries and fatalities involving motorists and construction workers. Despite the benefits of traditional workzone safety measures like barriers and signage, there is a need for additional crash mitigation equipment.

To save time and money on the repair of concrete highways, bridges & other structures, states are considering a Purdue innovation as an alternative to decades-old methods used for estimating when newly poured concrete is ready to withstand heavy traffic.
