A kind of traffic guidance system allowing bus travel without traffic lights restriction

Art: patent of the present invention relates to a kind of stop-go command system, be related specifically to a kind of be intended to eliminate urban traffic blocking have the intersection of traffic lights allow bus without traffic lights restriction travel traffic guidance system.

Background technology: in the intersection of existing traffic lights, bus is together with the mixed row of other vehicles, the all vehicles of one traffic congestion are all stifled, for Beijing, the non-bus number of trip and bus number ratio, be approximately 10: 1, can look at problem like this, i.e. ten most overloading 25 people of non-bus, and a bus at least can carry hundred people, the blocking caused by non-public transit vehicle, only have the bus of its quantity 1/10 also and then unlucky, the misfortune that 25 people invite, another innocent person more than 100 is allowed and then to suffer disaster, lose justice very much, although do not accomplish not allow non-public transit vehicle set out on a journey, but can public traffic in priority be accomplished, public transport is leading, the people more than 100 of this innocent person is allowed fast to go on a journey, so just occurred at the traffic guidance system having the intersection of traffic lights to allow bus travel without traffic lights restriction.

Summary of the invention: patent of the present invention proposes at the traffic guidance system having the intersection of traffic lights to allow bus travel without traffic lights restriction, it is based upon the traffic order that public traffic in priority and public transport are main, public transport a kind of new city intersection in principle in advance, its objective is to eliminate urban traffic blocking, smoothly going out the conveying of administrative staff with public transport.

See Fig. 2 of Figure of description, it is a Chinese city used stop-go command system figure, stop line (11) (17) (19) (32) and this paper are referred to as red greenish-yellow lamp (40) (42) (44) (46) of large red light, and south, west, north, the road of east four direction, constitute the fundamental of this traffic guidance system, such as travel green light northwards, then tell driver, the car of south orientation is only allowed to keep straight on, turn left to travel, certain right-hand rotation row is unrestricted, and other three directions are sent a car except right-hand rotation row, be parked in legal stop line (19) (11) (32) without exception, no through traffic, the order that green light is opened is by south, west, north, east right-hand circular, green light opening time long and short, then press big, the little prior setting of vehicle flowrate, general metropolis, green light adds second time about 30 of amber light, can to let pass about 60 meters of first-class automobile amounts to be released of long road, in second time at least 90 of a circle traffic lights circulation, if plug the automobile of 600 meters long, then need to wait just can cover these vehicles, the roughly description of Chinese city traffic state that Here it is 900 seconds (15 minutes).

See Fig. 1 of Figure of description, it is one is having the intersection of traffic lights to allow bus without the traffic guidance system figure of traffic lights restriction traveling to the used stop-go command system of Chinese city through what change, remove road rightmost track, if as they (1) (7) in Fig. 1, be decided to be the special runway of bus, outside forbidding non-public transit vehicle to be parked on this road and travelling, there are 2 changes, 1. to illustrate in the east, bus does not have red parking line, but not public transit vehicle red parking line is by the stop line (11) of former regulation, after move a segment distance, move on to new stop line position (9), and with this distance draw surely comprise reverse track, next door and middle tape as Fig. 1 (13) grid zone, it is the special swinging room of bus in the east, same way, define south, west, other three special swinging rooms of bus, north, as (24) (27) (35) in Fig. 1, 2. bus special swinging room red light command device is set up, claim little red light herein, the content that still it comprises for example explanation in the east, one, set up red light (8) and (12), because it is the vehicle two-way to the non-public transport of dealing all send order command, therefore its red light that to be two sides show simultaneously, the non-public transit vehicle that instruction will travel eastwards through this district and westwards travel, this district is then prohibited from entering when when red, when that I guess original large red light command system diagram 1 and Fig. 2 (40) (42) (44) (46) indicate non-public transit vehicle that is that allow this district eastbound and that head west to pass through, Dan Jiangai district little red light command device when red, also to stop travelling, stop outside this district, when this district little red light command device red light puts out, whether non-public transit vehicle allows eastbound in this district and heads west, must act according to the order of large red light command system (40) (42) (44) (46), they are two years old, set up the unlatching of the little red light command device in the special swinging room of bus and disconnect control system, to open unlike it with large red light command system and off-state can not be preset in advance, but provide according to the bus approached that signal carries out controlling, according to current electronic telecontrol technical level, can obtain very intelligent, but this belongs to him and manages it the thing of expert, this patent only describes its content controlled, send a car as example describes traveling road conditions below:

A. south is carried out vehicle to encounter large red light is when red, non-public transit vehicle all must at stop line (28) the red light such as to stop in South Road, and sailed bus (16) next, can not stop to continue to travel on its Nan Laizhuan road, when driving to several meters far away right-side signal receiver (15) places within original stop line (17), bus (16) must send craspedodrome to (15), one of left-hand rotation row two kinds of signals: when bus is right-hand rotation row, without the need to providing signal, bus (16) is kept straight on after turning right on special road, the right-hand bend completing intersection travels, as provided craspedodrome signal, then (8) (12) when red, when bus (16) sails to (14) position, soar in (13) in swinging room, bus (16) can be perfectly safe by this swinging room, when driving to (18) position, cut-off signal is issued to (10), (8) (12) red light puts out, bus (16) is kept straight on after turning right on special road, and the craspedodrome completing intersection travels, as provided left-hand rotation row signal, then (8) (12) when red, when bus (16) sails to (14) position, soar in (13) in swinging room, bus (16) can be perfectly safe by this swinging room, when driving to (18) position, (8) (12) cut-off signal is issued to (10), (8) (12) red light puts out, send (26) (20) start signal to (10) simultaneously, (26) (20) when red, when bus (16) sails to (23) position, soar in (24) in swinging room, bus (16) can be perfectly safe by this swinging room, when driving to (22) position, cut-off signal is issued to (21), (26) (20) red light puts out, bus (16) is kept straight on after turning right on special road, the left-hand bend completing intersection travels.

B. when south is carried out vehicle to encounter large red light is green light, non-public transit vehicle is all let pass, and by south orientation come on its special road, sail bus (16), when bus is when turning right row and craspedodrome, without the need to providing signal, if turn right row, bus (16) is kept straight on after turning right on special road, and the right-hand bend completing intersection travels; As kept straight on, keep straight in bus (16) footpath on special road, the craspedodrome completing intersection travels; If during left-hand rotation row, left-hand rotation row signal must be sent to (15), (26) (20) when red, when bus (16) drives to (23) position in special road, gently soar in swinging room (24), bus (16) can be perfectly safe by this swinging room, when driving to position (22), cut-off signal is issued to (21), (26) (20) red light puts out, bus (16) is kept straight on after turning right on special road, and the left-hand bend completing intersection travels.Above-described is that south is to travel road conditions, other west, north, three, east travel road conditions also all equally, and only bus comes to difference then little red light and signal receiver position also difference, because bus is minority actually, impact is had on non-bus, but not quite.
