Description

The utility model relates to visual aids for studying traffic rules.

Known teaching device for learning the rules of the road containing a table with replaceable maps, layouts of vehicles, control units and input response codes (AS No. 183501, publ. June 17, 1996).

The closest technical solution chosen by the applicant as a prototype is a device for assessing road safety, containing a base with a plot of a section of the road, made to scale, mock-ups of vehicles made with the ability to move on the scheme, characterized in that on the basis, at the beginning and at the end of the road section diagram, transverse slats with slots are installed in which flexible tapes are located, fixed in one of the transverse slats, and flexible tapes are installed in the zyah so as to form the movable portions located above the hazard level evaluation scale (patent for utility model RF №135172, publ. 27.11.2013).

The disadvantage of this device is the impossibility of fixing the occurrence of a danger when changing the direction of movement of the vehicle, if it occurs within the boundaries of the lane, as well as the inability to take into account the influence of the dynamic corridor of simultaneously moving cars and a sudden obstacle on road safety. It is known that traffic accidents can occur when dynamic corridors of parallel moving vehicles overlap each other.

The technical task of the claimed utility model is to assess the danger arising from the movement of vehicles along a lane, adjacent lanes and (or) the sudden appearance of an obstacle to the vehicle's movement, taking into account the dynamic corridor.

Achievable technical result - visualization of movement with deviations made by vehicles from the middle of the lane, taking into account their mutual approximation to each other.

The technical problem is achieved by the fact that the device for assessing road safety contains a base with a plotted section of the road section, made to scale, on the base, at the beginning and at the end of the section of the road section, transverse strips with slots are inserted into which flexible tapes are mounted, fixed in one of the transverse slats, moreover, flexible tapes are installed in the slots in such a way that they form movable sections above the hazard rating scale and are located above the marking lines bounding the conditional bands for Visions, prototypes of vehicles, characterized in that the device contains additional flexible tapes located in the middle of the conventional lanes, and prototypes of vehicles are located on additional flexible tapes with the possibility of moving them.

Comparison of the claimed technical solution with the prototype shows that it differs in the following features:

the device contains additional flexible tapes;

flexible tapes located in the middle of conventional lanes;

prototypes of vehicles are located on additional flexible tapes with the possibility of their movement on them.

Therefore, we can assume that the claimed utility model meets the criterion of "novelty."

The utility model can be manufactured on standard equipment, so it meets the criterion of "industrial applicability".

Figure 4. The position of vehicles A, B, C after vehicle B was forced to move to an adjacent lane due to braking and rebuilding of vehicle B.

Figure 5. The position of the vehicles A, B, C after the vehicle B has abruptly changed to an adjacent lane and forced the vehicle A to move into the oncoming lane in order to avoid a traffic accident.

The device operates as follows: when simulating a traffic situation, vehicle models are moved along additional flexible tapes located in the middle of the conventional lanes. Any deviation of the vehicle model from rectilinear movement in one direction or another will reflect the dynamics of the transverse movement of the vehicle, thereby determining the dynamic corridor of the car (the size of the strip necessary for the actual movement of the car) and be fixed by moving the movable end of the additional flexible tape.

For example, vehicles A, B, C are moving along two lanes of a road section, and vehicle B is approaching an obstacle (Fig. 2).

Vehicle B, approaching the obstacle, begins its detour without leaving the adjacent lane. On the device, this will lead to deformation of the additional flexible tape (pos. 7), the movable end of which will move in the slots of the transverse bar (pos. 11) along the scale (pos. 13), which estimates the level of danger (Fig. 3).

After the vehicle B starts braking and avoiding the obstacle, the vehicle B is forced to advance, moving at the same time to the adjacent lane. On the device, this will lead to deformation of the flexible tapes (pos. 3, 7, 8), the movable ends of which will move in the slots of the transverse bar (pos. 11) along the scale (pos. 13), which assesses the level of danger (Fig. 4).

Vehicle A moving behind at a higher speed, for which moving vehicle B will be an obstacle, will be forced to overtake by moving to the oncoming lane. On the device, this will lead to deformation of the flexible tapes (pos. 8, 4), the movable ends of which will move in the slots of the transverse bar (pos. 11) along the scale (pos. 13), which estimates the level of danger (Fig. 5).

Thus, we can artificially create any dangerous situations associated not only with overtaking, but also with advancing an obstacle without leaving the vehicle both in the adjacent and oncoming lanes with their simultaneous assessment on a scale (pos. 13). The danger of maneuvering depends on how far the vehicle has moved (key 12) to the adjacent or next lane. In addition, the device allows you to assess the danger to traffic caused by any moving vehicle within the lane within the dynamic corridor. The amount of movement, and, consequently, the danger of maneuver will be characterized by the length of the path traveled by the end of the flexible tape (pos. 2, 3, 4, 5, 6, 7, 8, 9) along the scale (pos. 13). The greater the number of divisions the end of the longitudinal movable spring band will pass (pos. 2, 3, 4, 5, 6, 7, 8, 9), the more dangerous the maneuver will be.
