Traffic sensors give cyclists green lights

Transport officials in Columbus, Ohio, are following in the footsteps of Austin, Texas; Portland, Oregon and Berkeley, California and recalibrating their traffic signal sensors to accommodate the growing number of cyclists in the city.

Transport officials in Columbus, Ohio, are following in the footsteps of Austin, Texas; Portland, Oregon and Berkeley, California and recalibrating their traffic signal sensors to accommodate the growing number of cyclists in the city.

Nearly all the city’s 1,000 traffic lights are connected to road sensors that detect the presence of vehicles at the intersections and adjust the lights accordingly. Cycles are another story; they don’t contain enough metal to trigger the sensor.  This has caused some cyclists to even run a red light that doesn’t change.

“It’s a big safety issue,” said Ray George, president of Yay Bikes, a Columbus organisation that advocates for cyclists. “It’s not the best situation for anybody.”

But local cycling advocates are giving the city high marks for what they say is a stepped-up response to their concerns.

Calls to 311, the city’s service line, and online requests at the 311 website will result in the city checking out a particular intersection and possibly recalibrating the sensors to detect bicycles.

“It’s been a process of going intersection by intersection for a while now,” said Rick Tilton, assistant director of the city’s public-service department.  Since February 2012, Columbus has made improvements at about forty-five intersections, Tilton said.

Gordon Renkes, an Ohio State University chemist who has been a certified instructor with the League of American Bicyclists for more than fifteen years, said the response has been a welcome improvement, especially for cyclists.

“This is one of the simplest, easiest and least-expensive things the city and traffic departments can do to help lawful cyclists,” Renkes said.

The technique is recommended by the National Association of City Transportation Officials as a way to reduce delays for cyclists while increasing safety and promoting cycling as a viable form of transportation in cities.

“We’re working with the cycling community, and Mayor Coleman wants to make this a more cycle-friendly city,” Tilton said.

    The US City of Greenville has begun phasing in new vehicle detection technology at its traffic signals. The state-of-the-art traffic sensors are expected to provide numerous benefits to motorists including improved safety, cost savings, greater mobility and increased productivity. The city’s 115 vehicle-activated signalised intersections currently have more than 900 in-road sensors that detect the presence of vehicles. The loop detectors, which have been widely used throughout the US for more than four de

    While initial cost of radar based detection may be higher than that traditional loops, lower maintenance costs more than balance the books. Following successful field tests, the US city of Greenville, North Carolina, has recently agreed a new policy of phasing in Wavetronix traffic sensor technology’s radar-based SmartSensor Matrix system across its signalised traffic intersections. City traffic engineer Rik DiCesare expects the incremental implementation to deliver benefits to both the city’s taxpayers an
