Brief description of the drawings
Fig. 1 plugs into website schematic diagram for subway.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Based on the bus signal priority control method of public transport subway brushing card data, comprise the following steps：
(1) period and section are divided.Wherein, the division period is, for a time cycle, to be drawn by week with one week
Point, and in a few days mark off morning peak period, evening peak period and flat peak period every.Because for working day, it is double stop it is even every
For its each period, traffic conditions all difference.Therefore, the period is divided using which can to distinguish Monday to Sunday every
The public transport vehicle-mounted objective moving law of day, while the public transport vehicle-mounted of daily morning peak, evening peak and flat peak period can also be distinguished
Objective moving law.
If the main line priority in section is Kl；If the priority of public transport flow direction is Kf；If the factor of influence of subway station is
Ym；If the crossing subway factor of influence at each two crossings of upstream and downstream is Y near subway stationj, upstream and downstream near the subway station
Each two crossings include upstream shortcut mouthful, upstream long way mouth, downstream shortcut mouthful, a downstream long way mouthful；If subway POP is preferential
Level is Kmf；If it is K that a certain crossing a direction presses circuit public traffic in priority level.
(2) in units of section, the sum of swiping the card of each public bus network in each period by the section is counted, to all
Section is ranked up by sum of swiping the card, and section is divided into the common n gear of 1~n from small to large according to ranking results, respectively to n grades
The K in sectionlAssignment, the bigger K of gear1It is bigger.
According to actual road conditions, section is divided into third gear in the present embodiment, the corresponding main line of 1~3 grade of difference is public transport branch road,
Public transport subsidiary road and public transport major trunk roads；Respectively to 1~3 grade of K in section1Assignment 1,2,3.
(3) in units of public transport flow direction, public transport flow direction includes circuit and up-downlink direction, counts the circuit in each period
The sum of swiping the card of the direction, is ranked up, according to ranking results from small to large by public transport to all public transport flow direction by sum of swiping the card
Flow direction is divided into the common m gear of 1~m, respectively to the m grades of K of public transport flow directionfAssignment, the bigger K of gearfIt is bigger.
Public transport flow direction is divided into 6 grades in the present embodiment, respectively to 1~6 grade of K of public transport flow directionfAssignment 1,1.1,1.2,
1.3、1.4、1.5。
(4) in units of subway station, the sum of swiping the card of the subway station each period Nei is counted, to all subway stations
By swiping the card, sum is ranked up, and section is divided into 1~6 totally 6 gears from small to large according to ranking results, respectively to 1~6 grade of ground
The Y of iron websitemAssignment 1,1.1,1.2,1.3,1.4,1.5；To YjAssignment, sails the Y in subway station direction intojValue is more than sails out of ground
The Y in iron website directionjValue.
To YjThe method of assignment includes：As shown in figure 1, for same crossing, when from east westerly direction be will be to
Up to subway station, conversely from west toward east to being then to leave subway station direction, then from eastern Y westerlyjValue is greater than from western past
The Y in eastjValue；For same direction, crossing respectively the B crossings and C crossings of subway station both sides are set in, if B to C
Direction by subway station, then the Y of crossing BjValue is greater than the Y at C crossingsjValue.
As shown in figure 1, closer to the crossing Y of subway stationjBigger, subway circulation direction is that from X to Y-direction, B is upstream
, for a upstream long way mouthful, C for downstream shortcut mouth, D are downstream long way mouth, X is other crossing (not shown)s, by excellent for shortcut mouthful, A
First level sequence B>A>C>D>X.Accordingly definition positioned at B crossings and will toward the crossing subway influence of the bus of C crossings traveling because
Son is Yjbc, crossing subway factor of influence of the definition positioned at A crossings and the bus that will be travelled toward B crossings is Yjab, define position
Crossing subway factor of influence in C crossings and the bus that will be travelled toward D crossings is Yjcd, definition is located at D crossings and will be past
The crossing subway factor of influence of the bus of X crossings traveling is Yjdx, assignment Yjbc=1.4；Yjab=1.3, Yjcd=1.2, Yjdx=
1.1；From from the point of view of the bus towards different directions at same crossing, by taking B crossings as an example, B to C directions Yjbc=1.4, B are arrived
A directions are to sail out of subway station direction YjbaValue should be with YjcdValue is mutually all 1.2；According to YmAnd YjCalculate Kmf, Kmf=Ym*Yj, non-ly
The K at the crossing near ironmf=1.
(5) K obtained to (4) according to step (2)l、Kf、KmfCalculate K values：
K=Kl*Kf*Kmf
And respectively by the corresponding K of certain circuit bus imparting in certain period section crossing upstream or downstream direction
Value, sets up database, when many buses meet at crossing, according to its affiliated circuit combination present period, road with these K values
Section, crossing and up-downlink direction read corresponding K values from database, and K values are bigger, and priority level is higher, gives priority pass.
This method provides data from plug into three aspects of main transit line, public transport flow direction and subway, with reference to this three aspect
Factor calculates the public traffic in priority level that a certain crossing a direction presses circuit, builds the current system of bus crossing priority, makes result
More comprehensive and reasonable, so that the traffic efficiency of the bus that handling capacity of passengers is larger, operation task is heavier, current rank is higher is improved,
So as to lift the whole efficiency of bus trip, alleviate traffic pressure, facilitate passenger to go on a journey.
