Abstract

The invention discloses an H-shaped urban arterial road public transportation system and belongs to the field of urban public transportation. In the system, H-shaped roads are constructed at non-motored lane positions of original urban arterial roads (more than or equal to 40 meters) to form an H-shaped independent public transportation network of which the upper part is special for non-motored vehicles and the lower part is special for buses; therefore, the transportation of the buses, non-motored vehicles and pedestrians operates on the edges of the arterial roads; and two motor vehicle lanes are increased in a central area of an arterial road because special bus lanes are shifted to the non-motored vehicle lane. Therefore, the capacity of the arterial road for bearing the traffic volume is obviously improved in case of invariable width.

Description

H type arterial street public transportation system

One, technical field

The urban public transport technology.

Two, background technology

Along with quickening of urbanization process, traffic congestion becomes us and lives in the problem that the people in city will face every day.For improving the traffic congestion situation, successively introduced subway, light rail, technology such as viaduct system and public transportation lane are constantly transformed the urban traffic system fast, but the thorough transport solution problem of blocking up all the time.Trace it to its cause, subway, light rail, quick viaduct system etc. finally will be connected with the urban ground traffic system, if the ground public transport system does not resolve, then the traffic congestion on ground will have influence on other traffic systems, is the core that transport solution blocks up so handle the surface transportation system problem in city well.The core of urban ground transportation network is that the red line width is at the major trunk roads more than 40 meters, allow major trunk roads bring into play carrying effect that the traffic volume increases, make it really become the urban traffic main artery, add that traffic jam issue just may be resolved with subway, light rail, viaduct system effectively is connected fast.

Three, summary of the invention

" H type arterial street public transportation system " is at the major urban arterial highway more than 40 meters at the red line width, research bus, bicycle (electric motor car, bicycle) and pedestrian's traffic organization technology, reduce the influence of this three, make the bigger traffic carrying capacity of major trunk roads transportation network performance the major trunk roads traffic.

Major trunk roads more than 40 meters generally all are provided with public transportation lane in the central area, the stream of people's collecting and distributing traffic to major trunk roads has caused considerable influence by bus, and potential safety hazard is more, so public transportation lane should be shifted.

With 40 meters roads is that example describes " H type arterial street public transportation system ", greater than 40 meters roads mainly is the track quantity that increases Road Center Area, and traffic organization technology and 40 meters roads of bus, bicycle (electric motor car, bicycle) and pedestrian are similar.

The general arrangement form in the cross section of 40 meters roads is: (sidewalk)=40,2.8 meters (sidewalk)+1.2 meter (disjunctor tree pond)+meter (nonmotorized vehicle lane)+1.2, meter (greenbelt)+11.5,3.0 meters (nonmotorized vehicle lane)+1.5 meter (3 motorways)+11.5 meters (3 motorways)+1.5 meters (greenbelt)+3.0 meter (disjunctor tree pond)+2.8 meters meter.Wherein, 2 nonmotorized vehicle lanes divide the left and right sides to arrange, separated by 1.5 meters wide greenbelts and motorway, the road middle section is made up of 2 public transportation lane+4 motorways.See Fig. 1 for details.

" H type arterial street public transportation system " at the cross section arrangement of 40 meters roads is: (sidewalk)=40, meter H type track, 2.8 meters (sidewalk)+4.2 [nonmotorized vehicle lane (on top)+public transportation lane (in the bottom)]+1.5 meters (greenbelt)+11.5 meter (3 motorways)+11.5 meters (3 motorways)+meter H type track, 1.5 meters (greenbelt)+4.2 [nonmotorized vehicle lane (top)+public transportation lane (bottom)]+2.8 meters meter.1.2 meters (disjunctor tree pond)+3.0 meters (nonmotorized vehicle lanes) of the original path left and right sides reconstruct into nonmotorized vehicle lane on top (guardrail height 〉=1.5 meter), public transportation lane (headway 〉=3.5 meter) are the H type track that the H type is arranged up and down in the bottom, keep to the side to link to each other with the sidewalk in H type track, separate by 1.5 meters wide greenbelts and motorway to road central authorities, the motorway of road middle section becomes 6 by 4, has on average increased effective carriage way in 8 meters wide (2 tracks).See Fig. 2 for details.

Ordinary Rd between intersection and the intersection is pressed Fig. 2 arranged in form, enters and takes following technical measures operation behind the zone, intersection: 1, the measure of nonmotorized vehicle lane and bus zone separated running; 2, bus freely turns to by its purpose of travelling at ground level road; 3, the runway plane of nonmotorized vehicle lane forms annular independently bicycle, pedestrian's rotary traffic platform [podium level carries out the transition to 〉=4.5 meters (across motorway) by 〉=3.5 meters, and width is greater than 7 meters] in this zone; 4, the sidewalk, ground in position with the suitable gradient and rotary traffic platform along connecing; If 5, the intersection has been built up the grade separation district, then the rotary traffic position of platform should be adjusted accordingly according to actual conditions, and motorway is separated fully with the rotary traffic platform on its top, takes their own roads.

Under the situation that does not increase original road width, the nonmotorized vehicle lane position of (〉=40 meters) build H type combined type rigid frame overpass with less investment in the arterial street, form top and specialize in bicycle (comprising the pedestrian), the public traffic network that bus travels is specialized in the bottom, make bus, bicycle (electric motor car, bicycle) and pedestrian's traffic in the operation of the edge of arterial highway, the motorway width of central area, arterial highway has on average increased effective carriage way in 8 meters wide (2 tracks), the ability that its carrying traffic volume increases obviously improves, transportation security environments significantly improves, the road speed of motorway can be accelerated, and can alleviate the traffic congestion in city to a great extent.Reason is: 1,4 motorways of former middle section become 6 tracks, increase by 2 tracks; 2, got rid of bus, bicycle [electric motor car, bicycle] and the pedestrian influence to road middle section motorway, road speed can improve; 3, bus zone links to each other with the sidewalk, makes things convenient for the pedestrian to take bus, and is convenient to the collecting and distributing of visitors flowrate; 4, H type track belongs to the traffic circulation network of independent operating, the non-separation of machine, has reduced the frequency that traffic accident takes place.

Four, description of drawings

Fig. 1 is that the red line width is the general cross section traffic layout schematic diagram of 40 meters urban road; Fig. 2 is that the red line width is the H type cross section traffic layout schematic diagram of 40 meters urban road.

As shown in Figure 2, the bicycle lane of former arterial highway build bicycle lane on top (guardrail height 〉=1.5 meter), public transportation lane (head room 〉=3.5 meter) are the H type track that the H type is arranged up and down in the bottom, keep to the side to link to each other with the pavement in H type track, separated by 1.5 meters wide greenbelts and car lane to road central authorities, the car lane in road center zone becomes 6 by 4, has on average increased effective carriage way in 8 meters wide (2 tracks).
