"How they traveled, what route they took to get to this location."
Alan Clark is the Director of Transportation for the HGAC.
"We'll be interested in if they traveled with other people, were they carpooling? Did they come in a particular kind of vehicle? We're particularly interested in if they used transit or walked to that location."
The responses are kept confidential, and won't be used to identify anyone. Clark says these surveys are really the only way transportation officials can get the kind of information they need.
"Its purpose is to really help us decide where and how to invest in highway facilities, transit facilities, improved sidewalks and bicycle trails — any number of different uses."
This is the first traffic survey of businesses in the Houston area in nearly 15 years. The survey is expected to cost $900,000, which will come from money already set aside in TxDOT's planning budget. It'll take about a year to complete. The results will be used in a new long-range traffic plan for Harris and adjoining counties that the HGAC hopes to finish by the end of next year.
