This study aimed to assess the impact of interacting with two infotainment systems, Android Auto and Apple CarPlay, on four driver performance measures: reaction time, driving behaviour, eyes-off road and self-reported performance. It also compared the results with other forms of driver impairment studied previously. Twenty regular Android users took part...

Many intersections around the world are irregular crossings where the approach and exit lanes are offset or the two roads cross at oblique angles. These irregular intersections often confuse drivers and greatly affect operational efficiency. Although guideline markings are recommended in many design manuals and codes on traffic signs and markings to address...

More than 90 percent of highways and roads in the United States are built using hot-mix asphalt (HMA) or warm-mix asphalt (WMA) mixtures, and these mixtures now recycle more than 99 percent of some 76.2 million tons of reclaimed asphalt pavement (RAP) and about 1 million tons of recycled asphalt shingles (RAS) each year. Cost savings in 2017 totaled...

Moisture increase in pavement subsurface layers has an essential influence on granular material properties and affects expected pavement performance. Over time, moisture variations in the base layer of a flexible pavement depend on water infiltration after rain and pavement surface conditions. Consequently, the base layer resilient modulus (MR) is decreased...

From the work that has been performed in Phase 1 of the Ultra-Thin Bonded Wearing Course (UTBWC) Snow, Ice, and Wind Effects TRS, we understand that UTBWC pavement occasionally experiences negative pavement performance attributes in cold weather, requiring additional maintenance (beyond typical treatments) to remedy. Observations indicate a phenomenon of ice...

The existing online mapping systems process many user route queries simultaneously, yet solve each independently, using typical route guidance solutions. These route recommendations are presented as optimal, but often this is not truly the case, due to the effects of competition users experience over the resulting experienced routes, a phenomenon referred to in...

This study developed a number of models to estimate the relationships between land use, transit ridership, household expenditures, and municipal spending, with a focus on small urban areas. First, a regression model was developed that estimated transit ridership in small urban areas as a function of service quantity, service characteristics, the unemployment...

This project refined the Natural Resources Research Institute’s (NRRI's) patented taconite-based repair compound, explored equipment options, and field tested/demonstrated a low-cost mechanized system that can efficiently mix and place the repair compound in larger quantities while minimizing or eliminating direct contact and hand mixing by...

This paper discusses whether changes in mobility practices affect value of travel time savings. It considers the relationship between the theory of the value of time and its practical application in traffic models and cost-benefit analysis. The discussion covers the need to distinguish variations in utility due to changes in the quantity and quality of time...

Pricing externalities from vehicle use such as road damage, vehicular emissions (both greenhouse gases and local pollutants), and congestion has become an important topic in the transportation sector in recent years. Road user charge pilot programs are being explored in various states in the U.S.; cities like New York and San Francisco are following in the...

Crash analysis methods typically use annual average daily traffic as an exposure measure, which can be too aggregate to capture the safety effects of variations in traffic flow and operations that occur throughout the day.  Flow characteristics such as variation in speed and level of congestion play a significant role in crash occurrence and are not...

The Regional Transportation Management Center (RTMC) at the Minnesota Department of Transportation (MnDOT) deploys a large number of traffic detectors in the Twin Cities’ freeway network and continuously collects traffic data. While RTMC mainly uses the data for traffic and incident management, the TFA (Traffic Forecasting and Analysis) office uses the...
