METHODOLOGY
In the study of the AVUPS, researchers enlisted participants with assistance from various stakeholders, including centers and facilities for PWDs, as well as community hubs like libraries…
METHODOLOGY
In this project, FDOT’s Gainesville maintenance and regional transit system bus depot was selected as the closed loop site, where a total of 26 test cases were designed to test safe…
METHODOLOGY
For the simulation case study, the average network delay improvement (the actuated delay minus the RIO Signal Solver delay) was assessed for 12 scenarios with four demand patterns,…
METHODOLOGY
The ADAS operated in stealth mode between January 4 and March 4, 2019, during which drivers did not receive alerts ("before" period). The system then operated in active mode between…
METHODOLOGY
This project involved an experimental study conducted in Gainesville, FL in 2019 to evaluate a commercially available speed-monitoring smartphone app. Trajectory and eye-tracking data…
Methodology
Four school zones equipped with beacons were selected for inclusion in a 5.7-mile driving circuit, and 50 participants drove through the circuit twice in an instrumented vehicle with the…
The city of Gainesville, Florida, where the University of Florida is located, has special signal timing plans for special events. In order for these plans to work, all traffic controllers in the city…
Content references source material no longer available at its original location.
RESULTS
A synthesis of various traffic signal retiming projects across the U.S. and Canada revealed that:
Delays can decrease by 13 to 94 percent.
Travel time can fall by 7 to 25 percent.…

RESULTS
A synthesis of various traffic signal retiming projects across the U.S. and Canada revealed that:
Fuel consumption can decrease by 2 to 9 percent.
Below are a few examples of successful…
Recognize that operator training is essential and critical. The operation of ATMA relies on a two-vehicle setup involving a human-driven lead vehicle. The decisions made by the lead vehicle's driver…
The lessons learned from the deployment of the RIO system were from development experiences, and the performance of the system with respect to the project goals and effects on vehicular and…
Modify school zone boundaries by direction and use high resolution GPS for higher lane-level precision to prevent false alerts. School zone boundaries are generally staggered in two directions (the…
Automated Truck-Mounted Attenuators (ATMA) offer potential benefits for safety and operational improvements in mobile work zones by eliminating the need for a worker to operate an impact protection…
Advanced Driver Assistance Systems (ADAS) have the potential to decrease crash risks or conflicts associated with public transit operations, which could lead to a safer, more efficient, and…
