Abstract
Description
- The present invention relates to a method for warning road users of obstacles on a road in the vicinity of a bus stop in connection with passengers exiting and/or boarding a bus which has stopped at said bus stop.
- The invention also relates to a warning system for carrying out said method.
- It is known to equip buses, especially school buses, with a flashing warning light in order to warn other road users that exiting and boarding is going on in connection with that a bus has stopped at a bus stop. The warning lights are arranged at the front as well as at the rear of the bus in order to warn the road users in both travelling directions that obstacles may occur on the road when they pass the bus stop. The warning lights are usually activated manually by the bus driver. One disadvantage with such a warning system is that it is only in the close vicinity of the bus that the warning lights will be noticed by other road users, who accordingly will not be noticed of the warning lights until they are far too close to the bus. This problem becomes even more serious when the bus stops at a bus stop which is located a small distance away from the road, so that the bus becomes completely or partially hidden by the surrounding vegetation to the road users passing the stop. Another disadvantage with the warning system is that the bus driver might forget to activate the same.
- The object of the present invention is to eliminate the disadvantages with the warning system described above and to provide an improved warning system and an improved method for warning road users of obstacles on a road in the vicinity of a bus stop in connection with passengers exiting and/or boarding a bus, so that an increased safety is obtained, for the passengers and other road users, with accompanying reduced risk of accidents.
- The method according to the invention is characterized in
- that a warning system is installed in a section of a road, said road section comprising said bus stop, said warning system comprising a first warning device, which is arranged on the same side of the road as the bus stop and at a predetermined distance from, and before, the bus stop, and a second warning device, which is arranged on the opposite side of the road with respect to the first warning device and at a predetermined distance from, and after, the bus stop, as seen in the travelling direction of the bus, said warning devices each comprising a digital two-way radio and an activatable warning equipment,
- that a digital two-way radio is installed in each bus which is to utilize the stop, said digital two-way radio activating the warning equipment of the first warning device when the bus passes a first position, wherein the digital two-way radio of the first warning device sends a signal to the digital two-radio of the bus as a confirmation that the warning equipment of the first warning device has been activated,
- that the warning equipment of the second warning device is activated by the digital two-way radio of the bus when the bus passes a second position, wherein the digital two-way radio of the second warning device sends a signal to the digital two-way radio of the bus as a confirmation that the warning equipment of the second warning device has been activated,
- that the warning equipments of both warning devices are activated when the bus is located at the bus stop,
- that the digital two-way radio of the bus deactivates the warning equipment of the first warning device when the bus has left the bus stop and passes a third position, wherein the digital two-way radio of the first warning device sends a signal to the digital two-way radio of the bus as a confirmation that the warning equipment of the first warning device has been deactivated, and
- that the digital two-way radio of the bus then deactivates the warning equipment of the second warning device when the bus passes a fourth position, wherein the digital two-way radio of the second warning device sends a signal to the digital two-way radio of the bus as a confirmation that the warning equipment of the second warning device has been deactivated.
- The warning system has the features specified in
claim 6. - The invention will be described further in the following with reference to the drawing.
