1. , a kind of traffic signal control system of leggy level-crossing, the road canal that comprises road surface in the crossing is drawn, the controllable signal display device, the phase place in road traffic signal control device and the control program signal and the topological structure of phase sequence, scheme parameters such as phase place execution time, phase sequence in being followed the procedure by signal control device takes turns to open each display device signal of letting pass by the view picture road surface that comprises in the bright out of phase in the out of phase time, make the traffic flow of traffic conflict obtain view picture road surface right of way at different phase times by turns, the road safety that can draw for each traffic flow canal in the crossing is characterized in that in an orderly manner by the crossing:

  • 1) have craspedodrome motor vehicle taboo in the region, center of crossing and sail the district, the motor vehicle of forbidding keeping straight on sails into;

    2) sail the outside, district canal in craspedodrome motor vehicle taboo and drawn craspedodrome autos only road, the drafting of drawing road across every canal has straight line, be called the half range safety line, the place of this half range safety line about apart from the clearance road 1-8 rice at first right hand inlet left-hand bend automobile traffic stream place, this canal of this bundle of lines is drawn road and is divided into two half range road surfaces, the near half range road surface of its middle distance import is preceding half range road surface, the near half range road surface of distance outlet is half range road surface, back, before the half range road surface track quantity can more than or equal import craspedodrome motor vehicle track quantity, be less than or equal to outlet motor vehicle track quantity;

    3) sail the inner canal in district in craspedodrome motor vehicle taboo and drawn left-hand bend autos only road, the drafting of drawing road across every canal has the half range safety line, this half range safety line distance is rolled the craspedodrome motor vehicle away from and is prohibited the place of sailing about district 1-8 rice, this canal of this bundle of lines is drawn road and is divided into two half range road surfaces, the near half range road surface of its middle distance import is preceding half range road surface, the near half range road surface of distance outlet is half range road surface, back, before the half range road surface track quantity can more than or equal import left-hand bend motor vehicle track quantity, be less than or equal to outlet motor vehicle track quantity with to the poor of motor vehicle track quantity that bend to right;

    4) the left-hand rotation car pass through craspedodrome autos only road to the craspedodrome motor vehicle prohibit sail the district inner in or prohibit to sail outside the inside, district to the craspedodrome motor vehicle and controlled by the half-roadway right display device;

    5) set half-roadway right display device comprises;

    can only give the preceding half-roadway right signal display apparatus that traffic flow enters preceding half range road surface right of way, allow traffic flow obtain the preceding half range road surface that view picture right of way prerequisite advances into the crossing;

    What can only give half range road surface, traffic flow use back right of way is back half-roadway right signal, allows the traffic flow that enters the crossing can leave the crossing if having time as early as possible;

    Can open forward and backward half-roadway right signal simultaneously bright as the display device signal of letting pass by the view picture road surface;

    The place that the traffic flow that all display device are placed in separately to be commanded separately can obviously be seen;

    6) described signal control device can be controlled view picture right of way signal, can control the half-roadway right signal again, if and had continuous several phase places all to comprise certain traffic flow all-clear, then this traffic flow all-clear could be continuous always, can not interrupt because of all-clear appear in phase tranformation;

    7) described system program has and also comprises the signal that some can only give these traffic flow half range road surface rights of way in some phase places, these phase places are let pass and are closely linked to each other before and after those phase places of signal of these traffic flows with comprising view picture on phase sequence, also open bright these and can only give the display device signal of these traffic flow half range road surface rights of way in the time of these phase places of execution.
