Definitions
- the invention relates to a method for determining Road routes, especially traffic information related to motorways, local detection cross sections by means of fixed detectors formed, traffic-related measured values recorded, preprocessed by means of local computers and to a given one Data protocol standardized, aggregated and sent to a higher-level radio Data processing system are transmitted.
- a traffic control and Information system which uses stationary Beacons and transmitter or receiver units arranged in vehicles Traffic flow information determined. From these Traffic flow information becomes, in particular, interference information determined to switch control signals.
- DE-P 44 08 547 describes a method for traffic detection and traffic situation detection on highways, preferably Motorways, known.
- lane-related measuring points are set up, which are equipped with traffic sensors, for example induction loops, for vehicle detection and with a traffic data processing device are provided.
- Traffic data such as vehicle speed, Traffic intensity and traffic density determined and from it certain traffic parameters in a traffic data preparation educated.
- Two neighboring ones form Measuring points a measuring section with a certain distance. Traffic parameters become from the traffic data of two such measuring points educated.

Beyond that the arrangement density of the fixed detectors depending determined by traffic expectation estimates. So you can through the arrangement of many local recording systems Build networks. With the invention it is also possible organize an overall network structure. On traffic technology critical positions are local detectors and preprocessing computers arranged by radio in preferably digital Technology the data to higher-level data processing systems forward or control centers. There can then be more Traffic models to which data are applied.
- linking the data to neighboring local acquisition cross sections can be a so-called route-related level of service in a higher-level data processing system or one assigned to the overall network Central can be determined.
- Measurement data are delivered, they are preprocessed, for example by calculating mean values, checking plausibility and trend factor determinations carried out become. From the changes in the data or the data itself status codes are then determined, for example in the form a numerical value for conditions such as free traffic flow, traffic jam, Stop and go, traffic jam or standstill etc. Evaluation cycles can be selected every 1 to 5 minutes, for example. However, the evaluation cycle can be set variably, for example depending on the status codes or Traffic conditions. The same applies to the data transfer rate, which, for example, depending on the determined Status code is applied, for example, with free flow of traffic Averaging every 30 minutes every 5 minutes. Depending on the fault condition, the transmission density increase. The data transfer rates neighboring acquisition cross-sections compared.
- the measured values can be recorded in relation to the lane, but what is not absolutely necessary, other detection cross sections can also be used To be defined. It is also fundamental possible, vehicle type differentiation values, for example Detect trucks, cars and the like.
