BELLEVUE, Wash. (AP) The city of Bellevue is using a high-tech version of a Segway electric scooter to survey its sidewalks and make sure they are adequate for disabled people.

The customized Segway is equipped with a laser, a distance-measurement instrument and other hardware. They will give city officials detailed information about sidewalk slope and surface variations that can make the sidewalks difficult to navigate.

The city east of Seattle has 336 miles of sidewalks, and officials hope to complete the surveying by the end of September.

The customized Segway was developed by the Office of Pavement Technology, part of the Federal Highway Administration.
