THEA tests connected vehicle technology in Florida

The Tampa Hillsborough Expressway Authority (THEA) in Florida trialled connected vehicle technology which it says could lead to collision avoidance in real life. The test was carried out as part of the THEA Connected Vehicle (CV) pilot, an initiative which relies on wireless communication between onboard units that have been mounted on poles along the Slemon Expressway and throughout downtown Tampa.

The 7384 Tampa Hillsborough Expressway Authority (THEA) in Florida trialled connected vehicle technology which it says could lead to collision avoidance in real life. 

The test was carried out as part of the THEA Connected Vehicle (CV) pilot, an initiative which relies on wireless communication between onboard units that have been mounted on poles along the Slemon Expressway and throughout downtown Tampa. A special rearview mirror was installed in eight vehicles to display safety alerts to drivers. 

The vehicles, equipped with onboard units, travelled in a line behind a lead driver who slammed the brakes on during rush hour conditions. The other drivers received an alert in time to take action and avoid a collision via a CV application called Emergency Electronic Brake Light.

A second test was conducted to show a single roadside unit could upload data from multiple cars travelling at a high rate of speed in 40mph. The tests showed that the system can collect data to help improve safety, improve traffic flow and evaluate the effectiveness of CV technology. 

Bob Frey, director of planning and innovations for THEA, says: “These tests provided crucial data that we can use to make further improvements to the system, which translates into improved safety and mobility for Tampa drivers.”

    Wisconsin's four-year HOT lanes pilot project, launched in May 2008, cost US$18.8 million to construct. Halfway into the project, which uses variably priced, or dynamic, tolling to improve highway efficiency, the benefits are mounting. The problem was obvious, and frustrating, to anyone who ever sat in bumper-to-bumper traffic on State Route 167 and watched a lone car whiz by every 20 seconds or so in the carpool lane.

Nearly 2,000 of these crossings are located on interstate highways, according to the American Road and Transportation Builders Association's recent analysis of the US Department of Transportation's 2016 National Bridge Inventory.

However you define a ‘smart city’, one of the key ingredients will be an efficient transport system. As most governments and city authorities face financial constraints, incremental improvements in the existing systems is the most likely way forward.
