Drivers are more accepting of on-road dynamic messages/warnings than in-vehicle message/warnings.
Findings
Average acceptance of on-road warning systems (73 percent) is higher than average acceptance of in-vehicle warning system (64 percent)
Drivers likely prefer on-road warning because they…

Implementing a collision-avoidance algorithm based on safe distance significantly reduces rear-end collisions in heterogenous fleets compared to other methods.
The study found two algorithms to be significantly more effective than others at reducing collisions towards the rear of the fleet. One of them minimized deceleration until hitting a "safe distance"…

Simulated use of dynamic eco-driving speed guidance strategy in vehicles shows an emissions reduction of 25 percent.
RESULTS
Drivers who were given eco-driving guidance were found to reduce the number of stops they made, and their vehicles had both total fuel consumption and total carbon dioxide emissions…

Evaluation of several transit signal priority systems found decreased bus travel time variability by 35 percent, lowered bus travel times by 6 to 27 percent, reduced AM peak intersection delay by 13 percent, and decreased signal-related bus stops by
ANN ARBOR, MICHIGANIn 1996, a test was conducted in Ann Arbor, Michigan that investigated bus priority using green extensions, red truncation (with and without compensation), and skip phasing (…
