Skip-stop ( English skip-stop ) - the organization of movement in which two routes follow the same path, but one of them passes without stopping one station, and the other the other. Travel time, compared with the usual route with all the stops, is less. It is used both on rail transport, and at buses. There is such a scheme of movement and the elevators, when they stop, for example, only on even floors.
In the system of the New York Metro [1] , the J / Z route is organized at rush hour in the peak direction. In the Philadelphia metro on the Blue Line, stations are divided into A and B for the respective routes. In the Chicago metro, such a scheme existed from the 1940s to the 1990s. The reason for the refusal was the following situation: if you need to get from the station with marker A to the station with marker B, you must go to the nearest station to B, and then wait for the train with all the stops. In the Santiago metro, such routes operate during peak hours on lines 2, 4, 5. There the red routes stop at red stops and the green routes stop at green stops.
Bus skip-stop routes pass stops at certain sites. In Seattle, there are blue, yellow, red and white routes, stopping only at stops of their colors. Prior to the extension of the Serpukhov-Timiryazevskaya line of the Moscow metro, a similar system operated on the Dmitrovskoye highway: different route numbers passed through a different number of stops; in turn, the trolley went with all the stops.
