Houston TranStar Expands Local Roadway Flood Warning System

July 13, 2020

Worried about driving during heavy rain and flooding conditions? Houston TranStar has an app to help. The Roadway Flooding Warning System app shows real-time traffic data and measures roadway flooding risks during heavy rainfall.

With hurricane season heating up, Houston TranStar urges people to download and use the new app. The project began in response to Hurricane Harvey, and the data expands weekly.

In 2019, the app showed 76 sensors. Today, it gets real-time data from almost 300 weather sensors that alert travelers to roadway flooding risks in Harris, Fort Bend, Waller, Brazoria, and Galveston counties.

Dinah Massie, Executive Director for Houston TranStar, explained the advantages of developing the app's capabilities.

"Expanding the Roadway Flood Warning System's footprint into counties adjacent to Harris allows us to warn even more people about potentially dangerous roadway flooding," Massie said. "Information collected by this highly accurate technology is overlaid on the TranStar Traffic Map and mobile application. We're warning motorists about flood risk and also helping emergency crews respond more quickly and safely during heavy rainfall."

The application is the result of a collaboration between Houston TranStar, the Harris County Flood Control District, and the Texas A&M Transportation Institute.

The Harris County Flood Control District, the Brazoria Drainage District, the City of Sugar Land, Fort Bend County, the Galveston Drainage District, Waller County, and the San Jacinto River Authority maintain the sensors, which increase the capacity to monitor water levels for possible local street inundation throughout TranStar's region.
