DETROIT (AP) — The latest variation of an Uber ride will require a short walk.

In eight U.S. cities, the ride-hailing company is rolling out a service called "Express Pool," which links riders in the same area who want to travel to similar destinations. Once linked, riders would need to walk a couple of blocks to be picked up at a common location. They also would be dropped off at a site that would be a short walk from their final destinations.

Express Pool could cost up to 75 percent less than a regular Uber ride. Express is running in San Francisco and Boston and soon will be offered in Los Angeles; Philadelphia; Washington, D.C.; Miami, San Diego and Denver. Uber says more cities will follow.
