On June 4, 2001, Tropical Storm Allison caused widespread flooding and damage in the Houston, TX, metropolitan region. Houston TranStar, a transportation management center that houses a consortium of four agencies -- TxDOT, the City of Houston, Harris County, and the Metropolitan Transit Authority of Harris County -- was responsible for providing transportation and emergency management services to the greater Houston area during the hurricane. Subsequently, the Texas Department of Transportation (TxDOT) commissioned an in-depth review of the operational response. Critical lessons learned were documented.

During peak of the storm, 26 inches of rain fell during one 24-hour period, and 34 inches was recorded in that week. The impact on Houston's Transportation System was severe; all major highways were closed and total damages amounted to $5 million. There was $1 million in roadway damage alone. Additionally, the flooding caused $3 million in damages to ITS and communication facilities. By June 9th, operational rates for Closed Circuit Television (CCTV) and dynamic message signs (DMS) had been reduced by 55.6 percent and 23.8 percent respectively.

Considering the scale of the flooding, Houston TranStar reacted well, continuing to function while several other government agencies and private organizations became non-operational.
