Embodiment 1
As shown in Figure 1, ultrasound is respectively set in the road shoulder appropriate location on the main road of highway and wait import on lane
Wave induction module and geomagnetic sensor module, and LED light group is mounted on each lane.Wherein, lane to be imported includes accelerating
Lane, transition lane.
When having when importing vehicle on lane wait import, the ultrasonic sensing module 1 being mounted on main stem is for detecting
Vehicle on to main stem；
The ultrasonic sensing device S1 of main road is mounted on for detecting main stem information of vehicles on the main stem, and by the main stem
Information of vehicles is transmitted to the MCU processor, wherein the main stem information of vehicles includes finally by the main stem vehicle for importing mouth
By the time, recently to which by the main stem vehicle for importing mouth, by the time, main stem vehicle is main stem phase by the time difference
The time headway T of adjacent two vehicles.
The acceleration lane that the earth induction module is set to lane to be imported can import part, for sensing vehicle to be imported
Information, and the information of vehicles to be imported is transmitted to the MCU processor；Wherein the information of vehicles to be imported includes institute
State vehicle commander L, the speed V of vehicle to be imported1；
MCU processor to it is described when away from T, the vehicle commander L of vehicle to be imported, speed V1, it is handled in the following manner:
Remittance mode (1): work as T > [(L × 3.6)/80] × 1.5+twAnd V1When >=80km/h, ring road vehicle is still accelerating
Lanes, the display for being now placed in ring road will show that SAFE (WARING is shown if being unsatisfactory for) prompt ring road vehicle can
With import safely (in view of stopping sight distance influence thus installation two pieces of displays).
Wherein, pre-warning time twThe selection of value and vehicle A acceleration aASize relation system is close, if aAValue is excessive, then
Driver's reaction time is short, and vehicle deceleration is too fast, will cause security risk, and driver comfort is poor, and discharge increases；If aAIt takes
It is worth too small, vehicle deceleration is slow, will affect smoothness, increases transit time.Usual braking deceleration 1.5~2.5m/s2 this
Comfort, safety and energy consumption can all be guaranteed in range.Take aA=2.5m/s2.The minimal reaction time is twAccording to when
Between and speed formula aA=(V0-Vt)/tw, wherein V0Normal speed is originated for vehicle, takes highway Maximum speed limit 120km/h.
VtThe speed for reaching merging area for vehicle takes 80km/h.The person of sailing reaction time tw=(120-80) × 1000/ (3600 × 2.5)=
4.4s, i.e., in X1=V0*twPosition carries out coordination early warning to vehicle A, similarly ring road vehicle acceleration time t1=(80-40) *
1000/ (3600 × 2.5)=4.4s, if vehicle accelerates to the speed per hour 80Km/h that can be imported from halted state and needs t2=(80/
3.6)/2.5, i.e. t=8.9s.
T is the time headway of two vehicle of main road；tfThe time that guidance information is made a response is seen for driver, from discovery situation
Judged that dominating trick again is operated, and is known as reflection interval this period to brain, is about needed 0.38 second.Foot is stepped on acceleration and is stepped on
Plate works to accelerator reaches acceleration effect, i.e. the acceleration transmission delay time, also known as the acceleration system reaction time, about needs 0.8
Second.Take tf=0.8+0.38=1.18s.
It is t according to the minimal reaction time of main road driverw=4.4s determines the installation site of each equipment.
Remittance mode (2): if ring road vehicle never imports chance in acceleration lane, driving to always transition, this
When work as T > t+twWhen, the LED light #3 prompt ring road vehicle positioned at transition end can import safely.
Remittance mode (3): if display it has been suggested that can not import safely, but lane vehicle to be imported still imports by force,
It is mounted on the LED light #1 of transition head end He other crossings, LED light #2 will flash, and remind A-road vehicle deceleration to reach
Careful row avoids the effect that accident occurs.
Remittance mode (4): condition is imported when 1 vehicle of main road and 2 vehicle time headways are unsatisfactory for ring road vehicle, monitors systems stay
It works, captures the time headway of 2 vehicles and 3 vehicles, and so on, information alert is carried out using display before transition,
It is prompted when ring road vehicle enters transition using the LED light of installation, guarantees the lasting guidance to vehicle.
In addition, LED light group, sensor group installation site is further arranged: LED1 and inductor S1 are mounted on away from nose X1
=120/3.6*4.4=146.67m；I.e. main road vehicle has decelerated to interflow normal speed 80Km/h just into merging area.
X3=Vt2/(2*aA)=98.77m；I.e. front occurs to guarantee that front vehicle has when ring road vehicle imports by force
Enough braking distances operate to carry out deceleration or lane change.
Expressway ramp speed limit V=40Km/h, in lane to be imported away from nose X2=V*twThe installation sense of the position=48.89m
Device S3 is answered, the time is rationally saved, when ring road vehicle process, and main road vehicle is just met for remittance condition ring road vehicle and can carry out
It directly imports, the arrival without waiting for the two cars of suitable time headway is being imported.
If vehicle, which enters transition just, to be allowed to import, it is contemplated that driver can correctly judge target following distance, at this time
Guide LED3 can be after capturing suitable time headway, carrying out giving a green light after t=L/ (80/3.6), (L is long for acceleration lane for prompt
Degree, tables look-up according to the actual situation), in order to which driver imports in time.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, related technology neck
The those of ordinary skill in domain, in the case where not departing from the spirit and scope of the utility model, can also make a variety of changes and
Modification, therefore all equivalent technical solutions also belong to the scope of the utility model, the scope of patent protection of the utility model is answered
It is defined by the claims.
