Abstract: A method for merging imprecisely localized traffic reports with precisely localized traffic data includes obtaining a plurality of possible positions (x) of the localized traffic reports having imprecise position indications. The plurality of possible positions is evaluated using overlap functions. Substantially precise positions for the localized traffic reports are defined by solving an extremum problem.

Abstract: A method for providing traffic information concerning one or more specific sections of a route to a traveler includes the steps of generating a bundle of traffic advisory messages for the traveler when an event relevant to the traffic situation has occurred in an affected section of the highway, wherein each of the traffic advisory messages present in the bundle of traffic advisory messages describes the traffic-relevant event in question at a different time within a defined interval and selecting a relevant message from the bundle of traffic advisory messages which is valid at a time relevant to the traveler.

Abstract: A reduction in telecommunications costs in the transmission of extensive data from a telematic terminal unit in a vehicle to a central station is made possible by a method for the transmission of location data implicating the location of the terminal unit in a traffic network at a point in time and of measurement data impliciting other characteristics of the traffic network at a location and/or at a time to the central traffic station, which location data and measurement data are detected by the terminal unit, particularly a telematic terminal unit for a vehicle. At least some of the data records transmitted from the terminal unit to the central traffic station contain only location data and some of the data records transmitted from the terminal unit to the central traffic station contain measurement data.

Abstract: A method for determining traffic data at points of interest in a traffic system from: vehicle data which are transmitted to a center from a plurality of vehicles relating to mean speeds (which have been determined over a time interval) of in each case one vehicle; stationary detector data which are transmitted to the center by stationary detectors in each case relating to the mean speed of vehicles passing a stationary detector in a time interval, wherein vehicle speeds at a point of interest are determined in the center, with the speeds which have been transmitted as vehicle data to the center being associated with defined points in the traffic system, and with vehicle speeds being calculated at in each case one point of interest by interpolation of at least two vehicle data items, namely by interpolation of stationary detector data measured in each case at at least one point in the traffic system and/or of vehicle data associated with at least one point in the traffic system.

Abstract: A method for detecting information on occupied parking space in a traffic network, in particular a town, uses a parking space detection control center. Parking space information relating to a stationary phase of a vehicle and the vehicle location is transmitted to the control center from a navigation system at the vehicle. Information relating to empty parking space is generated by the control center and information relating to empty parking space is transmitted from the control center to a navigation system at the vehicle end.

Abstract: Traffic status reports and traffic forecasts of a central traffic station are optimized by a central traffic station by a process for the completion and/or verification of data concerning the status of a traffic network in a central traffic station data of the following types are used for this purpose: measurement data measured up to the present time; status data that are calculated for at least a point in time prior to the current time concerning the status of the traffic network at this point in time; and forecast data calculated for a time in the past and concerning a future time with respect to this time in the past.

Abstract: A method for obtaining data on the traffic situation in a road network, wherein a plurality of vehicles involved in road traffic ("floating cars") and equipped with sensory analysis equipment for collecting traffic-relevant sensor data, which include at least one variable representing the current speed v(t) of a given vehicle, wirelessly transmit to a center at chronological intervals individual reports concerning the current traffic situation in the vicinity of the given vehicle determined on the basis of collected sensor data by a data processing device arranged in the vehicle.

Abstract: A process for obtaining traffic situation data in a compressed form, while largely maintaining the reliability of the data, whereby a speed profile for a vehicle that moves in traffic and belongs to a sampling vehicle fleet ("floating car") is found and transmitted wirelessly to a traffic center from time to time. The has the following features:a) The current speed of the vehicle is found continually in the vehicle.b) In the vehicle, characterizing numbers that characterize discrete segments of the vehicle speed profile are found from the current speed values, which characterizing numbers are characteristic of the curve of the speed actually travelled in the given segment.c) The discrete segments of the speed profile are formed continuously during the vehicle trip, in that the end of a current segment, and thus the beginning of a new segment, is defined on the basis of the results of a comparison between the speed profile of the vehicle and the speed profile of at least one virtual reference vehicle.

Abstract: A process and apparatus for determining traffic conditions using stationary data collection devices that are installed in a road network. The data collection devices collect data about traffic conditions at the respective installation sites in keeping with an established measurement and then forward the collected information to a traffic center in keeping with an established reporting procedure where the data is analyzed to determine the traffic condition. At least a portion of the results of the analyses of the traffic center is transmitted to particular data collection devices. The measurement and reporting procedures of the particular data collection devices are modified or influenced based on the results of the analyses of the traffic center and as a result the data transmissions between the traffic center and data collections devices are substantially reduced.

Abstract: In a housing (3) of an attachment piece (1), at least one hollow core space (5) for receiving one end of a corrugated tube (2) is available. In this hollow core space (5) between the corrugated tube (2) and the housing (3), a sleeve (4) is disposed into which the end of the corrugated tube (2) is inserted. On this sleeve (4) elastic elements (15, 16) are present which are pressed toward an axis (29) of the attachment piece (1), through an outer ring (23) on the housing (3). At least one of the elastic elements (15, 16) is equipped with one positioning element (20) and a locking element (24), with these elements (20, 24) engaging an aperture (21) in the housing (3). The connection between corrugated tube (2) and housing (3) can only be broken with an auxiliary tool and is therefore protected against unintentional detachment.

Abstract: A push button power switch with a thermal overload release and a snap-action contact breaking movement to which is added a snap-action contact making movement provided by a flexible leg portion on the switching slide which blocks the contact making movement by abutting against a nose of the switch housing while cocking a compression spring, until the push button, just prior to reaching its depression stop, triggers the contact making movement by deflecting the abutment tongue of the flexible leg portion away from the abutment nose of the housing. A cam slide with an inclined oblong cam wall and an integral flexible limb operates the snap-action contact breaking movement by controlling a spring-loaded latch slide.
