The City of Shreveport currently operates an antiquated traffic control system. Approximately 70 percent of our 350 traffic signals and their components are 60 years old. This outdated system does not permit communication between signals, specialized timing plans, or adjustments based on the level of traffic. As a result, Shreveport commuters experience unnecessary delays. Proposition 3 in the 2019 Bond includes much-needed funds for modernizing Shreveport’s traffic control system.
In the 1970’s, Shreveport maintained a state-of-the-art mainframe that connected all of its signals. This system was in use for more than 35 years. Unfortunately, a fire in the power supply destroyed this system in the early 2000s. We have since applied for and received $7 million in grants from the Federal Highway Administration. These grants have allowed us to make upgrades on several of our most traveled roadways.
The 2019 Bond will enable us to install an Intelligent Transportation System (ITS) at many of Shreveport’s signalized intersections. This system will give us the option of running multiple timing plans. It will also allow the signals to coordinate with each other, which means the system will moderate timing and adjust as traffic increases or decreases throughout the day.
Additionally, these intelligent traffic systems can prioritize emergency vehicles, increasing the response times of Shreveport Police and Fire. They manage pedestrian traffic more effectively as well, and better coordinate with school times in school zones. This is in contrast to the old system, which utilized a generic two-hour block in school zones.
On a technical note, these modern systems also allow for data collection, enhanced driver feedback, and better adjustments in the event of an incident. They are not as susceptible to catastrophic, system-wide effects either, because the technology and controls reside at the intersection, rather than a main-station. The signals themselves report issues and mechanical failures directly, instead of requiring someone to call in a trouble report. This enables technicians to assess and repair issues faster than is currently possible. Finally, Intelligent Traffic Systems utilize LED signal heads, which cuts costs and improves safety.
The City of Shreveport desperately needs to upgrade its traffic control system. Proposition 3 in the 2019 Bond addresses this critical need. It includes funds for a modern traffic control system, which will speed up commute times, save money, and make our roads safer. Citizens will vote on the 2019 Bond Proposal on Nov. 16.
