Wireless sensor solves traffic problem

Sandy Springs transportation officials have solved a rush-hour problem they hope will stick.

Crews have installed an underground traffic sensor at Mount Vernon and Roswell roads to correct a malfunction created by afternoon sunshine on the traffic signal cameras.

The new wireless, underground sensor detects vehicle presence and movement.

Transportation officials said that since the sensor was installed in December, reports of issues at the intersection have dropped to zero. They said they plan to install the device at other areas where the problem exists.
