Abstract

Method for relieving or preventing the undesirable effects of traffic jams in which the stop and go behavior of traffic is replaced by a stop and wait and go later without stopping behavior. Accordingly when traffic volumes build to a point at which stop and go traffic behavior occurs a sequence of traffic lights are used to control the traffic flow. The lights are set so that small groups or packets or vehicle are released sequentially from a queue head.

Description

Verkehrstauungen bedeuten in gewissem Sinn die mangelnde Berücksichtigung des Autofahrers durch die Verkehrsbehörden. Traffic congestion means in a sense the lack Consideration of the driver by the traffic authorities.

Zur Zeit bestehende Verfahren zur Auflösung bzw. Verhinderung von Stauungen, die den Verkehr auf weniger belastete Straßen umleiten, haben keine Wirkung, wenn keine alternative Straße zur Verfügung steht (z. B. an Grenzübergängen oder auf Autobahnen, in Unfallsituationen oder aber Baustellen infolge von Reparaturen). Current procedures for dissolution or prevention congestion that redirects traffic to less congested roads, have no effect if no alternative road is available (e.g. at border crossings or on motorways, in accident situations or but construction sites as a result of repairs).

Die Verfahren, die die Geschwindigkeit der Fahrzeuge beeinflussen (Wechselsignale, die eine adäquatere Geschwindigkeit vorschlagen), sind Verfahren deren Erfolg von der Respektierung durch die Autofahrer abhängig sind. Tatsache bleibt, daß wenn alternative Umleitungswege zur Verfügung stehen, sowohl diese als auch die erwähnten vorgeschlagenen Geschwindigkeiten durch Wechselsignale zwei Faktoren dieser bestehenden Verfahren darstellen, die nicht sicher manipulierbar sind. The processes that affect the speed of vehicles (Alternating signals that suggest a more adequate speed) Process their success from respect by drivers are dependent. The fact remains that if alternative diversions to the Are available, both these and the suggested ones mentioned Velocity through alternating signals are two factors of this existing Represent procedures that cannot be safely manipulated.

Das hier entwickelte Verfahren betrachtet, daß der Vermeidung des "stop and go"-Fahrverhalten erste Priorität zukommt. Das "stop and go" verursacht den höchsten Brennstoffverbrauch und die stärkste in einem Gebiet konzentrierte Gasemission. The method developed here considers that avoiding the "Stop and go" driving behavior has top priority. The "stop and go" causes the highest fuel consumption and the strongest in one Concentrated gas emission area.

Mit einem Verfahren, wie den hier beschriebenen, werden die Reisezeit und die Staustrecke anders behandelt. Die Fahrzeuge werden einem einzigen möglichen Fahrverhalten bzw. einem einzigen möglichen Weg gegenübergestellt. Using a method such as that described here, the Travel time and the storage section treated differently. The vehicles will a single possible driving behavior or a single possible one Faced path.

Die Reisedauer durch ein Staugebiet ist die Dauer des "stop and go"- Fahrverhalten. Diese Zeitlänge und die Länge des Staus, die der Abstand ist, den die Mobile in "stop and go"-Fahrverhalten durchfahren, werden behandelt. a) Dauer des "stop and go"-Fahrverhalten jedes individuellen Fahrzeugen x

The travel time through a traffic jam area is the duration of the "stop and go" driving behavior. This length of time and the length of the traffic jam, which is the distance that the mobile drive through in "stop and go" driving behavior, are dealt with. a) Duration of the "stop and go" driving behavior of each individual vehicle x

Die Hauptaufgabe des Verfahren ist das "stop and go"-Fahrverhalten mit einem von Erfinder so genannten "stop and wait, and go later without stopping"-Verhalten zu ersetzen. Das wäre die Zeitbehandlung. The main task of the procedure is the "stop and go" driving behavior with a so-called "stop and wait, and go later." without stopping "behavior. That would be the time treatment.

Die Strecken- oder auch Raumbehandlung beruht auf der allmählichen Verschiebung nach hinten von dem gesamten Stau, d. h. nach dem Gebiet von niedrigen Verkehrsmengefaktoren. The route or spatial treatment is based on the gradual shift backward from all traffic jam, i.e. H. to the area of low traffic volume factors.

Die Hauptaufgabe des Verfahrens wird wie folgt ausgeführt:
Nach der Identifikation des Staugebietes, meistens in einer Baustelle auf der Autobahn, die über mehrere Monate besteht, oder an einem Grenzübergang periodisch zu gewissen Zeiten des Jahres, oder in Unfall- Gebieten, o. ä., wird das ganze Sensor-Signal-Kommunikation-System installiert (s. Bild 1). Für Unfälle setzt das Verfahren ein sehr leichtes System mit leichten Elementen voraus. The main task of the process is carried out as follows:
After the identification of the congestion area, usually in a construction site on the highway, which exists over several months, or at a border crossing periodically at certain times of the year, or in accident areas, etc., the whole sensor-signal communication System installed (see Fig . 1). For accidents, the process requires a very light system with light elements.

Ein sogenannter Staukopf wird in jeder Stausituation von System oder durch Videoüberwachung festgelegt. Die Sensoren, die ab dem Staukopf in genügender Anzahl installiert wurden, sensieren die erwartete Befreiung der Kritischen Strecken (s. Bild 1). A so-called jam head is determined in every traffic jam situation by the system or by video surveillance. The sensors, which have been installed in sufficient numbers from the traffic jam head, sense the expected release of the critical sections (see Fig . 1).

Weitere Sensoren, die vom Staukopf weg nach hinten installiert werden, sensieren dem allmählichen und erreichten totalen Stillstand der Mobile. Additional sensors installed from the storage head backwards become aware of the gradual and achieved total standstill of the Mobile.

Die Strecke des Staus wird in Pakete geteilt. Die Länge der Pakete ist abhängig von der "Fahrkultur" und der Staugebietgeographie. Für gewöhnliche Staus infolge Baustellen, ist die Paketlänge ca. 100 m bis 200 m. Alle 100 m (in diesem Fall) werden Stop-Frei-Signale installiert, die die Pakete begrenzen und die Stop- und Frei-Signalen abgeben. The route of the traffic jam is divided into packages. The length of the packets is depending on the "driving culture" and the storage area geography. For usual traffic jams due to construction sites, the package length is approx. 100 m to 200 m. Stop-free signals are installed every 100 m (in this case) Limit packets and issue the stop and free signals.

Jedes Pakete wird sensiert. Die Sensoren sensieren im Prinzip entweder Stillstand oder Befreiung der sogenannten Kritischen Strecken nicht aber z. B. die Verkehrsgeschwindigkeit. Every parcel is sensed. In principle, the sensors sense either standstill or release of the so-called critical routes but not e.g. B. the traffic speed.

The procedure

Der Stau wird deklariert sobald innerhalb einer gewissen Streckenlänge "stop and go"-Fahrverhalten, d. h. sobald eine gewisse Anzahl Mobile im Stillstand sensiert werden und der Staukopf bestimmt wird, meistens gerade vor dem Ort, der den Stau verursacht. Dazu werden die ersten z. B. 200 m oder 300 m beobachtet. Es ist auch möglich eine Staudeklaration ab sensierter 1000 m "stop and go" vorzunehmen. Die Forschung in diesem Sinn zeigt aber, daß die Staudauer desto kürzer ist, je früher der Stau deklariert und behandelt wird. The traffic jam is declared as soon as within one certain route length "stop and go" driving behavior, d. H. as soon as one certain number of mobile devices are sensed at a standstill and the storage head is determined, mostly just in front of the location causing the traffic jam. For this, the first z. B. 200 m or 300 m observed. It is also possible a traffic jam declaration from sensed 1000 m "stop and go" make. However, research in this sense shows that the duration of the traffic jam the shorter the earlier the jam is declared and dealt with.

Sobald die Staudeklaration eintritt, wird das erste, am Staukopf installierte, Stopsignal aktiviert. Die vorliegenden Sensoren sensieren die Befreiung der Konfliktstrecke. Inzwischen werden in weiteren Paketen die Mobile eins nach dem anderen in den Stillstand versetzt. Die Sensoren sensieren den Stillstand und informieren die Computerzentrale, die das nächste Stopsignal für das zweite Paket aktiviert usw. Inzwischen wurde die Konfliktstrecke befreit und dem ersten Paket das Freisignal gegeben. Nach der Befreiung des ersten Paketes (oder nach der Befreiung der ersten Strecke) wird das zweite Paket befreit usw. bis die allmählich einsetzenden Freisignale das letzte eingegebene Stopsignal erreichen, und damit das Verfahren als erledigt deklariert wird (s. Bild 2 und 3, vgl. die Punkte bei den Signalen). As soon as the traffic jam declaration occurs, the first stop signal installed on the traffic jam head is activated. The available sensors sense the liberation of the conflict route. In the meantime, the packages have been brought to a standstill in other packages. The sensors sense the standstill and inform the computer center, which activates the next stop signal for the second package, etc. In the meantime, the conflict route has been cleared and the first package has been given the free signal. After the liberation of the first package (or after the liberation of the first route), the second package is exempted, etc. until the gradually released free signals reach the last stop signal entered, and the process is thus declared done (see Figs . 2 and 3, cf. the points on the signals).
