A need maintenance , even stop (s) on request , hold (s) at the request or optional (r) stop (Estelle) called, is a stop or a stopping point at which or on which a vehicle of public transport only after registration of a stop request stops by a passenger . On-demand stops are usually set up when there is either only a small potential for travelers or the stop is only used seasonally. The advantage is the shorter travel time due to the elimination of the passenger switching time , provided nobody wants to get on or off, and also the lower energy consumption due to the elimination of braking and starting. In particular, the earlier horse-drawn trams , which ran relatively slowly , often managed without any fixed intermediate stops. On-demand stops also increase driving comfort, since the elimination of deceleration and acceleration at stops where there is no need to brake leads to a more even and more pleasant travel experience.

Demarcation

The opposite of an emergency stop is the so-called compulsory stop , also called a compulsory stop , permanent stop , fixed stop , main stop or - for example in front of intersections - called a safety stop .

Also stops that are only on special occasions (e.g. sporting events, see Watford Stadium stop ) or temporarily (e.g. only during rush hour, only on weekends or only during school holidays), but then with a mandatory stop of at least individual journeys , are served, are not required stops in the sense of the above definition. The Tummelplatz stop of the Innsbruck Mittelgebirgsbahn , located at the Tummelplatz state memorial site, used to be a special case, and until 1985 it was only operated on All Saints' Day on November 1st. A similar regulation applies to the Rüttenscheider Markt stop of the Essen tram , which is only served during market times, i.e. only Wednesdays and Saturdays and only in the mornings on these days.

Need stops for tour groups

A special feature are demand breakpoints for travel groups . In this case, the means of transport only stops there if a previously defined minimum number of travelers want to get on or off, who have registered this request with the transport company in advance . One example is the Willingen-Stryck stop , which is located near the Mühlenkopfschanze .

Identification in timetables

In printed timetables, the required stop is usually indicated in accordance with the UIC leaflet 411 "Design, content and structure of the course books", which has now been repealed , by an "X" in front of the station concerned. If this only affects a certain train stop, the X is in the timetable table before the departure time.

Signaling variants

There are different variants for signaling the wish to stop, which depend on two factors: on the one hand, on whether the passenger wants to get on or off, and on the other, on the type of vehicle.

Options for identifying the entry request:

Stop by sight : the driver sees the passenger willing to board waiting at the stop. This is mostly used in omnibus , trolleybus and tram traffic . This method is also used on slow-moving railway lines .
Stop on signal : At many train stops, the passenger switches on a signal (in the area of application of the Ril 301 mostly a flashing Ne 5), which sends the driver the request to stop . This signal can also be transmitted electronically, for example from mobile or stationary end devices via cell phone networks (TCP / IP or SMS). The transfer from the request stop can take place directly to the vehicle or to a server, whereby the server must carry out the forwarding to the vehicle affected by the order.

Demand stops at which several lines stop can be a disadvantage. In this case, the driver has to stop in any case when passengers are standing at the stop, even if they are actually waiting for the car on another line. The same applies if there are passers-by at the stop who have no intention of traveling, but are simply waiting for someone or looking for protection from the rain. For the reasons mentioned, for example at the Flemish transport company De Lijn , passengers wishing to board have to raise their hands so that the vehicle actually comes to a stop.

Options for marking the wish to exit:

Stop at the push of a button : In most trams, trolleybuses, omnibuses and modern railcars , the passenger can communicate his wish to get off the vehicle by pressing a signal button . Usually, after pressing the button, a signal sign “Car stopping” or similar lights up, which indicates that the button was pressed successfully or that other passengers do not have to press it, sometimes combined with an acoustic signal that should also attract the driver's attention. Sometimes it is enough to press the door opening button in time to announce the stop request. In earlier times, instead of the electric push buttons, a cord stretched under the ceiling of the vehicle, the so-called bell cord, was used, which the passengers had to pull down to give the signal.

Stop on verbal request : In particular on railway lines that are used by older railcars or trains, the passenger must verbally communicate his or her wish to disembark to the conductor or the driver . While city and regional buses almost always have a stop request system (stop buttons) these days , this is often missing in combination buses that are suitable for short trips and further cross-country routes at the same time, as well as in very old cross-country buses.

Get off between two stops

Various transport companies offer their passengers the option of getting off between two regular stops - provided the driver classifies the additional stopping position as safe for traffic. More recently, this has been introduced in the outskirts of large cities, for example in 1990 at the Pinneberger Verkehrsgesellschaft (PVG) from 7:00 p.m. and all day on weekends. This is now offered on bus routes outside the inner city areas in the Hamburger Verkehrsverbund (HVV). With the Stuttgart trams (SSB), this is only possible from 9 p.m. on all bus routes outside the city center. A similar regulation already applied to the Stuttgart horse-drawn railway. Although this introduced fixed stations in 1878, it continued to stop at any point along the route at the request of passengers.
