Description

Limit, a kind of safety type bus track

Technical field:

The utility model relates to the town road field, limit, particularly a kind of safety bus track.

Background technology:

The mode of general public transport, long-distance bus junction vehicle parking mainly contains two kinds: run-in index is stopped and orthoscopic is stopped, respectively following Figure 1 and Figure 2.

Run-in index is stopped the track place breadth is had relatively high expectations, and is used for independently parking space, as the long-distance bus station more.Orthoscopic is stopped the track and is used to the collecting and distributing place of large-scale passenger flow (for example transport hub such as airport, the railway terminal) public transport of auxiliary construction, long-distance bus service station more, generally is fit to the thin-and-long place and arranges.

There are 2 deficiencies in orthoscopic stop mode:

First, when the parking stall of stopping the track fixedly the time, if will satisfy vehicle can once sail the parking stall into and can once roll parking stall (without reversing) again away from, bus length of wagon 12m as calculated routinely, need the long stop position (12m parking space+8m buffer area) of about 20m, even so, also higher when vehicle is gone into to driver's technical requirements, as shown in Figure 3; If will save land used, increase the parking stall, each stops the position minimum length can be reduced to 16m (12m parking space+4m buffer area), but vehicle need be gone into the position through reversing, and as shown in Figure 4, such mode is all unfavorable with current safety to the daily efficiency of service in limit, track.

The second, when the parking stall of stopping the track not fixedly the time, may produce following situation:

1) vehicle temporarily can't sail out of the parking stall in the middle of following distance excessively closely caused before and after, as among Fig. 5 because B, D spaces of vehicles tension cause the C car can't sail out of the parking stall;

2) following distance is big but be not enough to stop the 3rd car before and after, can only seek next suitable stopping into the position for the 3rd, as D, E spaces of vehicles among Fig. 5 big but less than the minimum reversing of F car go into the distance of positions from;

3) the preceding spacing of waiting is big but be not enough to stop the 3rd car, but the 3rd car causes the parking stall to rest in the buffering track because of underestimating or sailing this parking space by force into, will have a strong impact on pass through safety and traffic efficiency, can't go into the position fully as the F vehicle among Fig. 6;

More than five kinds of problems being occurred of two class situations can reduce the utilization rate on limit, track efficiency of service or limit, track.

Summary of the invention:

The purpose of this utility model is to provide limit, a kind of safety type bus track, guarantees that limit, track resource makes full use of, and saves the space, and safe in utilization convenient.

To achieve these goals, the technical solution of the utility model is as follows: limit, a kind of safety type bus track, comprise by the track, stop track and sidewalk, stop the track and be provided with the stop parking stall, it is characterized in that the highway sideline of stopping the track adopts limit, zigzag bus track, the parking stall be arranged in parallel along limit, zigzag bus track.For improving traffic efficiency, between by track and stop track, the buffering track is set, buffering track minimum widith is 3.5m.For the bus vehicle of length of wagon 8-13m, limit, zigzag bus track is formed by stopping the limit and sailing out of limit two parts, stops the length of side 10～15m, sails out of the length of side 4～6m, and it is 140 °～150 ° that two sidelines form the sawtooth angle mutually.

Advantage of the present utility model be it can:

Guarantee that limit, track resource makes full use of, and saves the space;

Satisfy vehicle and once sail into, roll away from, without reversing, easy to use;

Help vehicle and organize in order, fixedly random parking phenomenon is stopped in the parking stall, carries service for various collecting and distributing places provide efficient, safe passenger.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 7 is provided with schematic diagram for limit, bus of the present utility model track.Limit, illustrated safety type bus track, comprise by the track, stop track and sidewalk, stop the track and be provided with the stop parking stall, it is characterized in that the highway sideline of stopping the track adopts the zigzag design, the parking stall be arranged in parallel along roadside, zigzag road, wheelpath when passing in and out the parking stall like this is single, can conveniently pass in and out the parking stall, does not influence the vehicle pass-through by the track simultaneously.As shown in the figure, when B, D parking space when full, the bus vehicle also can sail the C parking space easily into, under similar circumstances, the bus vehicle also can sail out of the C parking space easily, whole process need be through reversing, the vehicle body gabarit can not invaded the track of passing by.

The limit, track is made up of 2 tracks at least, and 1 by track and 1 stop track; For improving traffic efficiency, general recommendations is provided with 3 tracks, and 1 by 3,1 buffering track 4 (providing vehicle to sail, roll away from transition into), track and 1 stop track 5.For guaranteeing that vehicle sails into, the gabarit track is limited in the buffering track when rolling away from, buffering track minimum widith is 3.5m.The sidewalk must be higher than the motorway road surface, and in general, the sidewalk is higher than stops the track, and sidewalk laying road kerbstone is provided with and highly is controlled between 10～15cm, to guarantee pedestrains safety and the facility of getting on or off the bus.

Limit, zigzag bus track of the present utility model adopts run-in index to stop the mode that combines with orthoscopic, with parking space length, angle design toothing in accordance with regulations, can in the requirement of satisfying the convenient security service of vehicle, improve limit, track resource utilization.Limit, zigzag bus track is formed by stopping limit 1 and sailing out of limit 2 two parts, stops limit 1 long 10～15m, sails out of limit 2 long 4～6m, and it is 140 °～150 ° that two sidelines form the sawtooth angle mutually.

The gabarite such as the following table of bus vehicle are listed:

Table 1 bus vehicle gabarit parameter (unit: m)

As shown in Figure 8, the bus vehicle sails out of the parking stall changes sufficient direction, sails out of angle with the safety of curb formation and is about 33 °, and the while is according to lane width, length of wagon and consider certain safe spacing, determines that the horizontal length of side of AB is 14m, the long 6.42m of BC hypotenuse.This preliminary geometry in limit, formed zigzag track is rotated slightly, and 2 of AC place the curb position, determine AC projected length 19.7m, as shown in Figure 9.

As can be seen from Figure 9, the car lateral extent of two buses in front and back is 1.25m, and by the actual travel capability analysis, this distance can be reduced, and corresponding BC also is reduced to 5.14m thereupon.

Adjusted bus rolls angle away from and geometrical model is seen Figure 10 and Figure 11.

After the adjustment, limit, zigzag bus track projected length is 18.3m, form by stopping the limit and sailing out of limit two parts, the parking stall projected length is 18.3m, stop the long 13.86m of limit AB, projected length 13.7m sails out of the long 5.06m of limit BC, projected length 4.6m, two sidelines form the sawtooth angle mutually and are about 147 °.Apart from 3.5m, the value of moving is 2.1m to the A point in the B point to the adjacent lane sideline.

Stop limit, length of side zigzag track and also can serve other vehicle, only need projected length, sawtooth angle to be calculated adjustment, be suitable for too by the parameter of service object's vehicle.

The stop limit on zigzag parking space is the narrowest with position, the corresponding sidewalk of the intersection point that sails out of limit width, and get on or off the bus cushion space and walkway two parts function have been concentrated in this position.The sidewalk minimum widith can be determined with reference to following formula:

B＝S+P

In the formula: the narrowest place, B-sidewalk width (m)

The S-desired minimum widith of cushion space of getting on or off the bus,

If last visitor's point Smin=2m

If drop-off point Smin=2.5m

P-walkway minimum widith (m)

(not enough 1m by 1m)

P=N/1850 wherein

N-walkway visitors flowrate (people/peak hour)

In general the sidewalk minimum widith is 4m～4.5m.

Limit, this zigzag track is through place operation test, and parameters can satisfy under the adjacent vehicle bit stealing situation, the space requirement of parking stall in the middle of conventional bus vehicle once sails into and rolls away from, and also gabarite is limited in the buffering track, do not invade and passes through the track.
