Definitions
- the invention relates to a traffic warning device, which is intended to be set up on roadsides, to detect traffic and, in particular, to alert traffic to wrong-way drivers (colloquially: "ghost riders"). that it is time delayed and locally inaccurate and requires the switching on of a radio station with locally responsible traffic in the car radio.
- the object of the invention is to propose a traffic warning system, which specifically warns the right traffic from wrong-way drivers or other traffic hazards such as traffic jams or accidents. "Targeted” means timely and especially in a danger area.
- the traffic warning device has a transmitting and receiving unit for a signal transmission, a sensor unit for detecting vehicles and a display for road users.
- the transmitting and receiving unit is in particular a radio unit for a signal transmission or a communication with other traffic warning devices and / or with a control center, for example a traffic control center or a police station.
- the transmitting and receiving unit enables communication with one or more traffic warning devices on the same road in and / or against a direction of travel.
- a traffic warning device detects a wrong-way driver, a traffic jam, an accident, a slow-moving vehicle on a high-speed road
- the traffic warning device can transmit a signal to traffic warning devices which are set up or arranged against a prescribed or intended direction of travel on the same road and the road users are placed on the - or generally indicate a danger when approaching the danger point.
- Distant road users, for whom there is no reason to slow down or use a right-hand lane, are not warned. This avoids, on the one hand, dehumanizing road users by warning them of a danger, but not of reaching a danger point, and conversely, road users are likely to rely on reaching a danger spot shortly when they pass a traffic warning device indicates a danger signal.
- the individual traffic warning devices serve as relay stations, which forward a signal of a traffic warning device.
- This allows short radio links to a potential center of an originally signaling traffic warning device via one or more other traffic warning devices to the center.
- a disturbance of a radio signal in the signal transmission by long radio links and possibly unfavorable landscape and / or weather conditions or buildings are largely avoided.
- a satellite-based signal transmission is not excluded, but can the Traffic warning device according to the invention also operate satellites independently.
- the sensor unit for detecting vehicles detects in particular against a prescribed direction driving vehicles, d. H. Wrong-way driver. It is also possible to park stationary vehicles, d. H. to detect a traffic jam or accident and to relay it to traffic warning devices in one or both directions to warn of approaching traffic. Even objects on the road can be detected and transmit danger information. Furthermore, detection and transmission of slow vehicles on high-speed roads is possible.
- the display of the traffic warning device according to the invention for the road users is in particular optical, for example a simple danger sign or even a more precise instruction such as speed limit, lane closure or legal driving requirement or even text information.
- the enumeration is exemplary and not exhaustive. Also, other than a visual display, such as an acoustic signaling, is possible.
- An embodiment of the invention provides that the sensor unit for detecting vehicles has a radar with which the traffic can be detected relatively reliably in terms of direction and speed.
- An embodiment of the invention provides a sensor unit with a light measuring system, in particular a laser measurement of vehicles. This also makes reliable detection of the direction and speed of vehicles possible.
- a development of the invention provides a light reflector, which reflects incident light in the direction from which it comes. In this way, a light beam can be transmitted from one traffic warning device to another traffic warning device whose light reflector reflects the light back to the one traffic warning device where the reflected light is detected. That's it in easy way possible to detect visual impairments by, for example, fog, snowfall, rain or, for example, by air pollution.
- An embodiment of the invention provides a sensor unit with a video camera and an image evaluation for detecting vehicles. This also makes it possible to detect the direction of vehicles, stationary vehicles and objects on the road, as well as slower vehicles.
- a video camera also has the advantage that a video image can be transmitted to a control center or the like, which allows an accurate and good assessment of the traffic and danger situation in real time.
- An embodiment of the invention provides a sensor unit with a temperature sensor.
- a temperature can be measured without contact.
- the temperature sensor or the sensor unit may have a thermal imaging camera and / or a pyrometer. Because motor vehicles with internal combustion engines are always heat sources, such vehicles can be easily detected with a temperature sensor, for example even in poor visibility conditions. Even if a speed measurement may only be possible inaccurately, at least the detection of the direction of travel of a vehicle is possible in order to warn against a wrong-way driver.
- a temperature sensor additionally allows a measurement of an ambient and in particular a road surface temperature, whereby, for example, a black ice warning is possible.
- the traffic warning device has one or two or more redundant sensor units for detecting vehicles.
- two or more redundant sensor units can achieve high accuracy and reliably avoid false traffic warnings.
- the traffic warning device according to the invention is suitable for automatic traffic warning without human intervention and delay.
- the traffic warning device preferably has its own power supply, for example an accumulator. This eliminates a connection to a power grid or other power supply, so that the traffic warning device can be set up with little effort.
- a refinement provides for a solar module for the power supply, which in particular charges a rechargeable battery, so that the traffic warning device is always ready for operation.
- An embodiment of the invention provides a post-shaped version of the traffic warning device, which can be easily set up and is suitable both for detecting vehicles as well as for the display for road users.
- the traffic warning device has a modular structure.
- One or more sensor units, displays and / or a transmitting and receiving unit can in principle be combined as desired, an adaptation to the respective local situation and requirement is easily possible.
- the traffic warning device can also be used as a reference point for self-propelled vehicles. For example, a lateral distance of a vehicle from the traffic warning device is detected, wherein the detection can be carried out both by the vehicle and by the traffic warning device. From the position of the traffic warning device with respect to, for example, a lane, the position of the vehicle on the lane can be determined and the vehicle steered.
- the traffic warning direction can also be set up temporarily as a reference point, for example in the area of construction sites, in order to guide self-driving vehicles through the construction site. For this, too, a simple installation of the traffic warning device, which in this case serves not as a traffic warning device but as a reference point, is advantageous.
- An embodiment of the invention provides a system of such traffic warning devices, which are arranged or placed at intervals on a roadside and, for example, on motorway ramps and departures.
- the traffic warning devices can be arranged or placed on one or both roadsides or on a roadside and a median strip.
- an arrangement or installation of the traffic warning device is provided on a roadside or on roadsides of directional lanes on which contrary to the prescribed direction driving vehicles are not overtaking but wrong-way driver.
