Method of increasing pedestrian crossing safety
SUBSTANCE: invention relates to traffic control, particularly, to hardware to prevent automobile-pedestrian accidents. Pedestrian with mobile electronic device, for example, mobile phone analysing traffic conditions by signals of pickups, video cameras and lights receives signals on pedestrian crossing safety level and permissive signals for crossing.
EFFECT: higher safety of crossing, particularly for poor-eyesight and blind pedestrians.
The invention relates to security systems, in particular to improve the safety of pedestrian crossings.
There are ways to improve the safety of pedestrian crossings through traffic lights with audible signals (GOST R 51648-2000) and warning "speed bumps".
However, known methods provides a relatively low safety crosswalks as a pedestrian on the basis of visual information may not always correctly assess the security level of the transition, which is determined by many factors, including distance to approaching vehicles, their speed, flow, weather conditions, etc.
The technical result achieved by the invention is improving the safety of pedestrian crossings.
This result is achieved in that way improve the safety of pedestrian crossings by warning systems is that the pedestrian is approaching a pedestrian crossing shall be warned about the risk for pedestrian crossing by a mobile electronic device, such as a mobile phone, which is based on the analysis of information about the included light, the distance to approaching vehicles, their speed, intensity of flow of the transport medium is in, about weather conditions located at the entrances to the pedestrian crossing sensors and cameras, generates and outputs a sound or other signals corresponding to the level of danger signals about the permission or prohibition of transition, with similar electronic devices may also be located in vehicles to alert drivers of approaching pedestrians.
The way to improve the safety of pedestrian crossings is illustrated by a figure.
The way to improve the safety of pedestrian crossings is implemented as follows. When you approach a pedestrian to pedestrian crossing on his mobile electronic device, such as a mobile phone, located at the entrances to the pedestrian crossing sensors, cameras and traffic light enters information about the distance to approaching vehicles, their speed, the intensity of the flow of vehicles, about the included light, weather conditions, in which addresses are formed and given sound or other vibration, light) signals corresponding to the security level transition at the moment, and signals are formed on the operational management of traffic lights, signals about the permission or prohibition of the transition. At the same time similar electronic devices can be placed in vehicles for preventing the lead drivers of approaching a pedestrian crossing pedestrians.
This way at the expense of additional warnings can increase the level of safety of pedestrian crossings. Also this method will be effective for the visually impaired and blind pedestrians.

SUBSTANCE: map of the controlled road network is formed; each traffic section is assigned a speed index; up-to-date information is received from fixed sensors on traffic speed on sections of the road network and based on this information, speed indices are corrected; on all sections of the road network, for which there was correction of speed indices based on up-to-date information, the average speed Va is calculated without taking into account the correction as well as the average speed Vb, for each section of the road network for which there was no correction of the speed index based on up-to-date information; the speed index is corrected by multiplying the speed index of each section of the road network by a function Ka(x) of the ratio X; data on the current location of the subscriber and the final point of the route are obtained and the optimum route is calculated.

SUBSTANCE: road trains continuously moving via crossways are formed. Number of vehicles in a train and duration of traffic light permissive signal is set according to established average speed of trains traffic and length of intervals between crossways. Traffic interval between trains is set equal to time of traffic light permissive signal action which is the same for all crossways on the highway. Operation of traffic lights on adjacent crossways is performed in reverse phase. Approach of head vehicles of each train to crossway is performed at the moment when traffic light permissive signal switches on by means of scanning by train head vehicle drivers the information about time to traffic light permissive signal switching on from colour digital traffic light and other indicators installed in each running interval at side or at top. At the same time, this is the instrument to form volume of each road train. According to scanned from indicators information, drivers manually perform necessary vehicle speed correction or this correction is performed automatically. Maintaining quasiconstant number of vehicles in each road train in consequence of to their loss due to leaving the highway is performed by road train replenishment with vehicles from highway crossing directions under entrance traffic light permissive signal with joining to corresponding road train. This signal is switched on according to a signal from sensors carrying out permanent recalculation of vehicles in each road train at given loss of vehicles in a train.
EFFECT: higher throughput on a highway with crossways.
