Description
Technical field
The utility model belongs to traffic safety technology field, is specifically related to a kind of exit of interchange initiatively apparatus for deivation of highway.
Background technology
Along with the enhancing of china's overall national strength, the theory of " people-oriented " deepens continuously, and the safety of highway will be following focal point.But the interchange ramp of highway is always the section that takes place frequently of expressway traffic accident.The accident of exit ramp is that in whole interchange ramp position, occurrence frequency is the highest, accounts for 70% of ring road total number of accident.Wherein one of reason is that the traffic guide sign of the exit of interchange of highway is more passive, is mainly manifested in the following aspects:
1. the Limited information of the traffic guide sign of the exit of interchange of highway.Driver can only grasp macroscopical distance, the volume of traffic that cannot be well understood to this section and the time reached needed for outlet on the one hand.Especially often there is speed perception error in driver after the long distance of highway is run at high speed, and inevitably there is underestimating oneself travelling speed, and the distance of running at high speed is longer, underestimates degree more serious to the road speed after reduction of speed.On the other hand, driver does not see speed(-)limit sign too soon due to driving sometimes, and add the limited amount of traffic sign, driver is easily just slightly slowed down when entering ring road and finally caused driving over the speed limit, and during sharp turn, operation is late.
2. the indefinite sighting distance that will cause flowing out point is bad, driver can not see structure and the ring road trend of exit portion ahead of time, if when deceleratuib lane is simultaneously again run-in index, then more can not freely, effectively utilize length of deceleration lane and effectively controlling party to, thus cause traffic hazard.
3. time inclement weather (ice and snow weather, thick fog weather etc.), attachment coefficient and the road visibility of road obviously reduce, driver holds inaccurate to safe driving speed, and the static speed-limiting messages suggested by speed(-)limit sign cannot agree with actual road and weather condition completely.
Based on above background, study a kind of exit of interchange initiatively apparatus for deivation of highway, for driver provides sufficient information (comprising the scheduled time of arrival outlet, control rate and lane change position etc.), make driver comprehensively understand front road conditions and be very important.
Utility model content
The purpose of this utility model is to provide a kind of exit of interchange initiatively apparatus for deivation of highway, for driver provide in time, traffic information fully, guide driver's safe driving, reduce traffic hazard, the raising traffic capacity.
For achieving the above object, the utility model have employed following technical scheme:
Comprise the multiple traffic information display unit being arranged at interchange outlet front, described traffic information display unit is arranged along road bearing of trend interval, wherein, spacing is left between first traffic information display unit in described interchange outlet front and described interchange export, each traffic information display unit includes the variable information advices plate be supported in above road and the radar trap being arranged at this variable information advices plate position place and meteorological monitor, the static traffic mark being used to indicate lane change is provided with between described first traffic information display unit and the traffic information display unit adjacent with its (referring to first traffic information display unit).
Described traffic information display unit also comprises single-chip microcomputer, and described variable information advices plate, radar trap and weather monitoring device are connected with described single-chip microcomputer respectively.
Described single-chip microcomputer adopts AT89C2051.
Described variable information advices plate adopts F type single-column to support variable information advices plate.
The described setting position place being used to indicate the static traffic mark of lane change is provided with variable information advices plate.
Described traffic information display unit also comprises the static traffic mark be connected with variable information advices plate.
Described radar trap adopts HT204 type radar meter.

Distance between adjacent two traffic information display unit is less than the distance that tests the speed of described radar trap.
The beneficial effects of the utility model are embodied in:
The exit of interchange active apparatus for deivation of highway described in the utility model is by arranging the traffic information display unit at multiple interval in interchange outlet front, the radar trap of traffic information display unit, weather monitoring device and variable information advices plate can be utilized to obtain in time, upgrade and show speed-limiting messages, timely prompting driver reduces the speed of a motor vehicle, changing Lane, ensures traffic safety.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of traffic information display unit described in the utility model;
Fig. 2 is the theory diagram that generation speed-limiting messages and expectation reach Outlet time;
Fig. 3 is the installation site figure of the exit of interchange active apparatus for deivation of highway described in the utility model;
Fig. 4 is the installation site figure (for 5# in Fig. 3) of each ingredient in traffic information display unit described in the utility model;
In figure: 1 is variable information advices plate, 2 is weather monitoring device, and 3 is radar trap, and 4 is static traffic mark.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
See Fig. 1 ~ Fig. 3, from be about the place of 2km apart from exit of interchange, traffic information display unit (being called 1# unit ~ 5# unit) is overlapped in installation 5.Often overlap the radar trap 3 that traffic information display unit includes single-chip microcomputer (adopting AT89C2051), variable information advices plate 1 and be arranged at this variable information advices plate 1 position place and (for obtaining the information of vehicle in section, comprise average velocity
with volume of traffic Q) and meteorological monitor 2 (being mainly used in obtaining temperature data and visibility data), 1# unit is apart from the distance L of outlet
1taken into full account that driver is to the cognition-course of reaction of variable information advices plate and the memory time to information, table 1 gives L
1recommendation.Due to the Limited information of variable information advices plate display, therefore variable information advices plate and static traffic mark 4 can be adopted to merge the mode arranged, the static traffic mark at 1# ~ 4# unit place is Warning Mark (effect comprises the length providing distance outlet).1# ~ 4# unit is equidistantly installed, and spacing is 400m, to ensure that radar can measure interval interior all vehicles (for HT204 type radar meter, its distance that tests the speed is about 500 meters).The static traffic mark of 5# unit is except showing except the information of identical category with the static traffic mark at 1# ~ 4# unit place, driver also will be reminded to change in time, according to the investigation of a large amount of actual vehicle lane change position, and in conjunction with driver cognition-course of reaction, 5# unit be selected in apart from outlet
place (L
subtractfor length of deceleration lane), the static traffic mark at 5# unit place will increase " please changing in time " printed words below Warning Mark simultaneously.After cell position is determined, carried out the setting of initial value at single-chip microcomputer input port by computing machine, after setting, radar trap 3 and meteorological monitor 2 are all connected to the input port of single-chip microcomputer to obtain data, the output port of single-chip microcomputer is connected with variable information advices plate 1 and is placed in after variable information advices plate 1, static traffic mark 4 and variable information advices plate 1 (adopting F type single-column to support) are placed side by side, particular location and highly arrange and see Fig. 4.
