The City of San Antonio has a population of more than 1.4 million people— and is expected to grow by at least a million individuals within the next 20 years. Rapid growth required the city to seek smart, efficient expansion of its infrastructure and services. For instance, the city’s Traffic Management Center must be prepared to handle greatly heightened roadway usage.
The Traffic Management Center, with a staff of 16 people overseeing nearly 1,400 intersections, is responsible for traffic signal operations, lane control, sensor-based detection devices and nearly 60 video cameras that facilitate real-time monitoring.
The city’s traffic system is finely tuned. Even minor disruptions and technical issues can drastically hinder motorists’ ability to proceed through several green lights in succession during normal traffic flow.
What the city needed
In 2015, the City of San Antonio recognized the need to upgrade its complex traffic management system, which included a dozen radio towers throughout the city. About 300 intersections, featuring access points connected to wired lines, were serving as reference nodes for the remainder of the intersections, each of which featured a wireless access point.
