College and university students in the Greater Toronto and Hamilton Area (GTHA) account for more than 600,000 daily commuters on an already crowded transportation system. To better understand the habits and needs of students who use transportation, StudentMoveTO began researching ways to improve student transportation in 2018. Ten universities and colleges from...

The Minnesota Department of Transportation conducted a 12-month distance-based fee (DBF) demonstration that utilizes existing technologies embedded within shared mobility (SM) fleet vehicles and connected and automated vehicles (CAVs) to automatically calculate and collect the fees. As part of the demonstration, researchers at the Humphrey School of Public...

Digital message signs (DMS) are a vital part of the advanced traveler information systems (ATIS) that disseminate various real-time travel information to the road users, including traffic diversion, travel time, congestion, upcoming roadwork, lane closures, and incidents such as accidents. Other information includes inclement weather, speed regulations, special...

The use of roundabouts in rural areas of the US is growing rapidly. For roundabouts constructed with concrete pavement, joint layout can be especially challenging. To reduce the need for sophisticated joint layouts, consideration is being given to constructing roundabouts without joints and instead using structural fiber reinforced concrete (FRC) to bridge any...

Although the use of recycled asphalt materials (RAM) in new asphalt mixtures can reduce the amount of virgin and nonrenewable materials required and increase the rutting resistance of pavements, it may also compromise cracking resistance. To mitigate this issue, asphalt mixtures containing RAM may require the use of a softer binder or recycling agent (RA)....

For several decades, stated preference (SP) studies have been the dominant method for transport valuation. However, there are many indications that revealed preference data is making a strong comeback due to access to Big Data and new analysis possibilities such as machine learning. In this report, we assess the capability of different RP data sources. We find...
