Abstract
Abstract In a method for traffic determination, a routing and information system for individual motor vehicle traffic is used, in which by way of stationary routing station poles, route information and local information are transmitted to the passing vehicles. For the determination of the traffic situation, the traveling times between two routing station poles are measured in individual vehicles with timing units. These traveling times are transmitted, together with the local information of the first routing station pole passed by a vehicle, to the second routing station pole and are considered in determining new route recommendations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
187 words
In a method for traffic management in a routing and information system for motor vehicle traffic having a network of stationary routing stations each located in the vicinity of a roadway, in which the routing stations transmit route information and local information concerning their positions to passing vehicles, and in which a trip destination is input into a device onboard a vehicle and transmitted therefrom to a routing station for evaluation so that specific route recommendations may be selected, the improvement therein comprising: transmitting, from a first routing station to a passing vehicle, a message including suggested route data constituting a vector chain, the address of the first routing station and a start command; receiving the message from the routing station in the device onboard the vehicle, storing the route data in the onboard device, and activating a travel time measuring device in the vehicle with the received start command; and transmitting, after traveling to a second routing station along the path suggested by the route data, the address of the first routing station, the route data, and the elapsed travel time to the second routing station.
Claim 2
Dependent Claim
187 words
In a method for traffic management in a routing and information system for motor vehicle traffic having a network of stationary routing stations each located in the vicinity of a roadway, in which the routing stations transmit route information and local information concerning their positions to passing vehicles, and in which a trip destination is input into a device onboard a vehicle and transmitted therefrom to a routing station for evaluation so that specific route recommendations may be selected, the improvement therein comprising: transmitting, from a first routing station to a passing vehicle, a message including suggested route data constituting a vector chain, the address of the first routing station and a start command; receiving the message from the routing station in the device onboard the vehicle, storing the route data in the onboard device, and activating a travel time measuring device in the vehicle with the received start command; and transmitting, after traveling to a second routing station along the path suggested by the route data, the address of the first routing station, the route data, and the elapsed travel time to the second routing station.
Claim 3
Dependent Claim
41 words
The improved method of claim 1, and further comprising the steps of: transmitting the measured travel times from a plurality of vehicles traversing the same route to a routing station; and forming a changing mean value from the measured travel times.
Claim 4
Dependent Claim
57 words
The improved method of claim 2, and further comprising the steps of: measuring the travel times between individual points along a vector chain included in the stored route data; storing the individual travel times in the vehicle; and transmitting the stored travel times and the stored route data to the next routing station along the suggested path.
Claim 5
Dependent Claim
36 words
The improved method of claim 1, and further comprising the steps of: storing, in a vehicle, deviation data when the vehicle deviates from a suggested route; and transmitting the deviation data to the next routing station.
Claim 6
Dependent Claim
35 words
The improved method of claim 4, and further comprising the steps of: counting the number of vehicles which deviate from the recommended route passing a routing station; and evaluating the traffic situations between routing stations.
Claim 7
Dependent Claim
23 words
The improved method of claim 2, comprising the step of: interrupting operation of the time measuring device in response to interruptions of travel.
Claim 8
Dependent Claim
27 words
The improved method of claim 2, and further comprising the step of: altering the route recommendations when a predetermined number of vehicles deviate from the suggested route.
Claim 9
Dependent Claim
37 words
The improved method of claim 1, and further comprising the step of: transmitting, from the first routing station, route recommendation data concerning a route starting at the second routing station and directed towards the first routing station.
Claim 10
Dependent Claim
83 words
The improved method of claim 1, and further comprising the steps of: storing, in a vehicle, deviation data when the vehicle deviates from the suggested route; transmitting the deviation data and the measured travel time to the next routing station along the suggested route; transmitting travel times and deviation data reported by vehicles from the routing stations to a central computer; evaluating the data at the central computer and forming new route recommendations; and transmitting the new route recommendations to the routing stations.
