摘要:
The present invention relates to traffic control devices designed to register vehicles and monitor traffic using vehicle identification. The objective of the invention is to simplify the system in order to make it single-band, to use a magnetic frame placed under the roadway instead of antenna fixtures over the road or at the roadside, as well as to provide safe and reliable functioning of the system while detecting and identifying fast-moving vehicles with HF-band ultra-long-range induction systems. The induction vehicle detection and identification system comprises electronic identification means with electronic memory, mounted on vehicles, and a reader capable of reading and/or writing data obtained from HF-band electronic identification means, wherein electronic vehicle identification means are integrated into the vehicle's license plate and the electronic memory unit is non-volatile; and wherein the reader is equipped with a magnetic frame, which is put into a dielectric casing installed approximately 1 m beneath the roadway, wherein the said frame generates alternating magnetic field making up its detection and identification coverage, which is as wide as the lane, up to 2m long, and reaches at least 1 m above, when signals reaching the frame are excited with power of up to 1W; and wherein the minimum time the reader requires to read discrete responses generated by electronic identification means and to identify a vehicle does not exceed 25 ms and conforms to the vehicle speed of up to 250 km/h; and wherein electronic identification means and the reader are capable of exchanging data with each other at the rate of at least 1 Kbit/sec; and wherein electronic identification means and the reader are capable of encoding and decoding data, as well as restricting data access.

The invention relates to a method for adapting the driving-off behavior of a vehicle (1) to a traffic signal installation (2), in which method the traffic signal installation (2) permits passing in a first state and forbids passing in a second state. By means of vehicle-to-X communication means, state information and time information of the traffic signal installation (2) are received by the vehicle (1) and forwarded by the vehicle to a traffic light phase assistance system. Furthermore, the vehicle (1) receives presence information comprising at least position indications from surrounding vehicles (4, 5) that are capable of vehicle-to-X communication. In addition, the position of the vehicle is determined by means of position-determining means. The method is characterized in that the position indications received by means of vehicle-to-X communication are displayed to the driver and the driving-off behavior is adapted in dependence on the state information and the time information and the presence of surrounding vehicles that are not capable of vehicle-to-X communication. The invention further relates to a corresponding system and a use of the system.

The invention relates to a method for calibration of a road surveillance system (1). Said road surveillance system (1) is adapted to monitor a surveillance area (8) of a road (15) and comprises a plurality of vehicle surveillance means. Said plurality of vehicle surveillance means are adapted to measure a position of a vehicle passing said surveillance area (8) and are synchronized with a global timing signal. The method comprises, in order to calibrate said plurality of vehicle surveillance means such that a position determination of said plurality of vehicle surveillance means is equal, passing a calibration vehicle (5) through said surveillance area (8). Said calibration vehicle (5) is provided with a plurality of predefined calibration markers (6). Said calibration markers (6) are provided at predetermined positions upon said calibration vehicle (5). During the passage of said calibration vehicle (5) through said surveillance area (8) each measurement means measures a position of an assigned calibration marker wherein said measuring is performed at a predetermined time and compares a measured distance between the positions of said calibration markers (6) with a reference distance between the positions of said calibration markers (6) and calibrating said plurality of vehicle surveillance means such, that the measured distances between the calibration markers (6) correspond to the reference distances between said calibration markers (6).

This publication describes a method and a system for registering use of studded decks (6) and for collecting due toll for use of studded decks on a vehicle (19) having at least one studded deck (6). This is done when a vehicle (19) passes over a detection device (1) on a road surface (18) of a road, the detection device (1) being associated with one or more sensors (2) that is able to detect impulses created by the decks (6) on the vehicle (19) that passes over the detection device (1). The impulses are registered and compared with a pre-determined value that enables a processing device (3) to determine whether one or more of the decks (6) are provided with studs or not. The system is configured in such way that the processed signal provides basis for collecting toll or at least bringing this fact to the attention of the driver and that toll is due.
