Implementation of Digital Infrastructure Technologies in Florida Revealed a 93 Percent Increase in the Proportion of Compliant Trucks Bypassing the Weigh Stations.

METHODOLOGY

This summary focus on the 12 DI deployments. According to ITS America, DI is the data, communication systems, servers, routers, hardware, sensors, software applications, and computing resources used to facilitate information sharing through data exchanges and platforms. DI supports information exchange among users, companies, devices, and public agencies. The 12 DI deployments were:

• “Artificial Intelligence (AI) Crash Response Management”, Southern Nevada
• “Traffic Management and Optimization”, Detroit, Michigan
• “Improving Bridge Travel Times With Lane Management”, Richmond, California
• “Using Active Traffic Management & Dynamic Lanes”, Southeast Michigan
• “Optimizing Traffic Flow on Congested Highways”, Bay Area, California
• “Decreasing Wrong Way Driving on Expressways”, Tampa, Florida
• “Smart Work Zone Systems”, Clark County, Washington
• “Improving Safety on Tribal Roads”, Toppenish, Washington
• “Streamlining Freight Weigh Station Operations”, Florida
• “Creating A Centralized Transportation Data Hub”, Utah
• “Building a Modern Traffic Management System”, Colorado
• “Improving Road Illumination with TxDOT”, Fort Worth, Texas

FINDINGS

• A fully cloud-based Artificial Intelligence (AI) crash response management system deployed in Southern Nevada made available to Nevada Highway Patrol employees through their mobile devices showed that 43 percent of crashes were detected faster than 911.
• The implementation of cloud-based remote traffic management systems deployed at major intersections in Detroit, Michigan, reduced travel times by 30 percent.
• Installation of lane use signs for improving bridge travel times in Richmond, California, resulted in 13 to 14 minutes reduction in peak weekday travel times, and a 70 percent reduction in crashes on the eastbound bridge approach.
• Deployment of active traffic management and dynamic lanes in Southeast Michigan resulted in a 50 percent reduction in southbound crashes.
• Deployment of advanced traffic management systems for optimizing traffic flow on congested highways in Bay Area, California, led to the peak period congestion on I-80 almost diminishing completely.
• A wrong way entry detection application launched for decreasing wrong way driving on expressways in Tampa, Florida, led to the detection of 14 wrong-way drivers over a nine-hour period.
• Smart work zone systems deployed in Clark County, Washington, led to the construction being finished six days ahead of schedule, saving $5.5 million.
• Pilot deployment of a cost-effective AI sensing device for improving safety on tribal roads in Toppenish, Washington, demonstrated the feasibility of cost-effective, low-power devices for real-time traffic monitoring. 
• Deployment of a central data management platform for streamlining freight weigh station operations in Florida resulted in 60 percent of compliant trucks bypassing the weigh station under the new digital system, corresponding to a 93 percent increase from pre-deployment year of 2019.
