Houston's speed reader board is collecting data for the rest of January.
"What we want to do was compare the data from when the machine was off to when it's on," said Carl Lutz, Ministry of Transportation district manager for Bulkley-Stikine.
During December 2012 it was collecting data with the display off, and in January it is collecting data with the display turned on.
They want to record data for the same length of time each way and then they will compare the two sets of data, said Lutz.
The speed reader board is intended to alert speeding traffic and get them to slow down.
On the west side of Houston where the speed limit is 70 to 50 kilometres per hour, Lutz says the board flashes "Slow Down," when vehicles are travelling over 80 kilometres per hour.
Most of the time the display shows "Your Speed" and flashes at those travelling over the speed limit, and the speed of the flashing depends on how much above the speed limit the vehicle is travelling, Lutz said.
"At 70 kilometres an hour, it flashes faster then it would, say, at 53, and the flashes slow down as you're slowing down," said Lutz.
The analysis and results of the study being done will be published in the Houston Today when the study is complete.
