3. the micro road environment comprises highway section in the ordinary city, quick highway section, fastlink and loop highway section, and comprises unidirectional bicycle road, two-way bicycle road, two-way two tracks, and the road, divide the fork, viaduct, all possible road environment such as crossroad can satisfy the different demands of studying.
Description of drawings
Fig. 1 is the synoptic diagram of a preferred embodiment of traffic simulation sand table model of the present utility model.
Wherein: the 1-track; The 2-greenbelt; The 3-lane line; The 4-viaduct; 5-divides the fork; The 6-crossroad; 7-and road; The 8-traffic lights; The 9-traffic sign.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Figure 1 shows that a preferred embodiment of traffic simulation sand table model of the present utility model.This traffic simulation sand table model is the important component part of automatic driving vehicle verification platform, is the running environment of micro vehicle.It comprises the traffic key element of making by real roads environment micro, and this traffic key element mainly comprises track 1, but the agent structure in this track 1 formed by the wood board splicing of some assembly and disassembly, this plank should be not yielding, and guarantee fully dry.In addition, road 1 both sides is equipped with lighting installation, and track 1 is provided with traffic sign 9 and traffic lights 8 respectively, and these traffic lights 8 can be handled by telepilot or self-actuated controller, also can set by artificial.But by the track agent structure that the wood board splicing that adopts by some assembly and disassembly forms, make that this traffic simulation sand table model is reconfigurable to build different traffic scenes, use flexibly, and be easy to deposit and carry.
Preferably, this plank adopts the shape of rectangle, so that deposit or splice.
Further, at the armoring coating in plank surface spraying one deck black car chassis, the asphalt surface of simulating real roads.This coating is elaxtic seal, and its flexible material behavior is consistent with the physical characteristics of asphalt surface, and its friction force is fit to vehicle and travels very much, the situation of wheel-slip can not occur.In addition, this coating can leave plank and water separation effectively, avoids the corrosion of wood materials.
Further, because propylene material has rapid-curing cutback, the color persistence is good, of long duration can oxidation yet, flavescence, hardening and then catalysis comes off, and harmless characteristics are so adopt acrylic paints to draw white lane line 3.The acrylic paints of preferred dilute with water is so that clean and revise.
In sum, by the black track 1 of adopting the armoring coating in spray car chassis and the white lane line of drawing with acrylic paints 3, the high emulation simulation true road environment.When carrying out image acquisition, because the track rough surface that the armoring coating in chassis covers, light generation diffuse reflection has guaranteed the quality of image acquisition; And track 1 is obvious with lane line 3 contrasts, is subjected to illumination effect little, is easy to processing and identification.
In order to satisfy different research demands, track 1 comprises highway section in the ordinary city, quick highway section, fastlink and loop highway section, and comprise all common road environments such as unidirectional bicycle road, two-way bicycle road, two-way two tracks and road 7, branch fork 5, viaduct 4, crossroad 6, make this traffic simulation sand table model possess certain complexity, can satisfy the demands of different researchs and guarantee the high confidence level of result of study.
Further, the layout in track 1 and size, traffic sign 9, traffic lights 8 etc. all design according to national standard, press with the equal proportion micro, size, shape, color, installation site are with reference to the configuration that needs of true traffic environment, thereby guarantee micro environment closing to reality as far as possible, improved the confidence level of platform experiment.
Contain at sand table under the situation of necessary traffic key element, if the micro ratio is too little, then some key element is too little, is not easy to view and emulate; If the micro ratio is too big, then the floor area of sand table is bigger.Therefore, the micro ratio of all traffic key elements such as the layout in preferred track 1 and size, traffic sign 9, traffic lights 8 and real roads is 1:10, makes the sand table size to fit, and is easy to view and emulate and manage.
In addition, between the incorgruous track of same road, be provided with greenbelt 2, and laid green carpet at the white space of model and simulated the lawn, the authenticity of micro environment has been guaranteed in above measure, make this sand table model as the vehicle verification platform that travels, with a high credibility, achievement in research is applicable to the real roads environment.
This sand table can be used as the travel environment of model vehicle, and the integrality of its element and authenticity guarantee to satisfy overwhelming majority's experiment and checking demand in the traffic technique research, and be significant for carrying out of intelligent transportation field related work.
Above embodiment only is used for explanation the utility model, and is not to restriction of the present utility model, and the those of ordinary skill in relevant technologies field under the situation that does not break away from spirit and scope of the present utility model, can also make a variety of changes and modification.Therefore all technical schemes that are equal to also belong to protection category of the present utility model.
