Police are investigating whether dogs are being used as escalators at a number of high-traffic intersections in Seattle.

The dog escalators were installed last year, said Officer Andrew Buell, a Seattle police spokesman.

The city is also testing a new dog-walking detection device, and police hope to have the device on the streets by early 2019.

Buell said the city has been working with the King County Metropolitan Transportation Authority to install the escalators.

One of the escalator locations in Seattle has already been tested.

In August, the dog-walker detection device was deployed at the intersection of 19th Avenue SW and Broadway SE, and at an intersection at 19th and Washington Streets SE, said Sgt. John Riggs, a King County Metro Police spokesman.

Police also deployed dog walkers at an Eastlake intersection, where dog walker detectors have been installed, he said.

“We’re using the technology to keep people safe,” Riggs said.

“We’re also using the sensor to keep dogs away from the escalater.”

One dog escalator is installed at the entrance to a high traffic intersection in Seattle, according to a police spokesman’s statement.

King County Metro police also have installed the detection device at a street in downtown Seattle and in an intersection in the downtown neighborhood of Northeast Seventh Avenue SW.

Officers at the King Center, a high crime area in Seattle’s Central District, also have been testing the device at intersections where dog-walks are currently in use.

There is also an escalator in a low-trafficked neighborhood on the south side of Northeast Sixth Avenue SW, said Lt.

Chris Wilson, a spokesman for King County Transit.

If the escalations are being deployed, they could cause an increase in traffic and a reduction in police presence, Wilson said.

A dog-walker detection device is also installed at a low traffic intersection, he added.

Cases of dog-caused escalator accidents have been reported in Seattle and King County, but no fatalities have been recorded.

No injuries have been confirmed, said Buella, the Seattle police officer.

The department has not received any reports of dogs being used to climb escalators, he told The Washington Post.

Although dogs can be used as an escalators if the dog is trained to do so, the detection devices can detect them only if the escalating dog is on its leash or on a leash that is tied to the escalATOR.

Other Seattle police departments are using dog-triggered escalators in high-crime areas.

At a high volume intersection in downtown, the police department installed a dog-tracking device, which uses sound to alert officers of dogs that are near the entrance of the high-frequency traffic intersection.

Dogs are also used in the northbound lane of Northwest 25th Street SE, where a dog walk is being installed.

More dog-trail escalator testing is also underway at the corner of Northeast Third Avenue SW in Northeast Seattle and on the westbound side of Northwest Third Avenue SE, a police spokeswoman said.
