Chapel Hill police and town officials are cracking down on speeding on Hillsborough Street.
According to a traffic study conducted by the town in the fall, less than 10 percent of all drivers on the street’s steep incline drive less than 25 mph — the posted speed limit.
“It’s an issue because of the downhill slope from top to bottom,” said Maj. Tony Oakley of the Chapel Hill Police Department. “You just about have to ride your brakes the whole way down, but most people don’t think to do that.”
Town officials monitored the speeds of Hillsborough Street drivers after several residents petitioned the Town Council to remedy the problem last January.
The traffic study tracked the speeds of drivers at three different locations on Hillsborough Street over a seven-day period.
According to the study, speeding is worst at the bottom of the hill between Bolinwood Drive and Airport Road, where average speeds exceeded 40 mph.
Upon completion of the study, town officials posted additional speed limit signs as well as a speed display mechanism.
The display, which was installed in December, will serve as a deterrent for speeding once it is activated in the next couple of weeks.
Kumar Neppalli, the town’s senior traffic engineer, said the speed display will simply flash the speed of cars as they pass. He said it will not be used to issue citations.
