Overflow detector: an occupancy detector positioned about 100-150 meters from the exit of the intersection.
Phase position: a set of traffic flows for which right of way is simultaneously acquired in one signal period.
Bottleneck control: in the process of dredging road network traffic, attention is paid to certain bottleneck intersections (a part of road networks are paralyzed after congestion), and special control is carried out on the congested phases and the associated phases, such as drainage, current limiting and forbidden entry.

A method for monitoring bottleneck control state comprises the following steps:
step 1: drawing the crossing background of the single crossing control:
the intersection is divided into four-fork (east-west-south-north), three-fork (east-west-south, east-west-north, east-south-north and west-north) and road section type intersection (east-west road section and south-north road section). And drawing a channelized and stop line of the intersection on the intersection control by combining the intersection type of the real intersection.
Firstly, setting the background color of a control as RGB (98, 98, 98), trisecting the control in the vertical and horizontal directions, dividing the control into 9 grids with the same size, and drawing the intersection boundary by using a black solid line along a side line according to the intersection type of a real intersection.
Secondly, stop lines and channelized separation lines in all directions are arranged, each direction comprises an entrance lane and an exit lane, the entrance lane comprises a left lane, a straight lane and a right lane, 3/4 accounts for the width of the road in the direction, the exit lane accounts for 1/4 the width of the road in the direction, the stop lines are represented by white solid lines, the exit lane and the entrance lane are separated by yellow solid lines, and the left lane, the straight lane and the right lane are separated by yellow dotted lines.
Step 2: and (3) displaying related real-time light states on each entrance lane of the control:
a countdown control is added before each entry lane to indicate the remaining free time for the phase of the lane representation. The number of seconds remaining for each phase (i.e., countdown) is represented by the size of the number on the countdown control, the number colors (red and green) represent whether to go (red and green), and the yellow time is included in the green time without separately counting down.
And step 3: associating data on each entry lane of the control:
each phase-related data includes phase flow, release time of the phase in one period, and variation of the release time of the phase in the current period and the previous period, and the 3 types of data are displayed in 3 columns in the east-west direction and in 3 rows in the north-south direction. The sequence of the distance from the center of the intersection is the phase flow, the release time of the phase in one period and the variable quantity of the release time of the phase in the period and the previous period. Wherein the flow display number is white in units of vehicle/minute; the number displayed by the release time of the phase in one period is green, and the unit is second; the digital color displayed by the variation of the phase release time of the current period and the previous period is determined according to the value of the variation: if the variation is greater than or equal to 0, the digital color is green, otherwise, the digital color is red, and the unit is second.

And 7: displaying the phase real-time lamp state:
when the intersection in the tree structure is clicked, the interface is divided into 9 grids with the same size, 5 intersection controls are loaded, and the intersection controls are arranged according to the real direction sequence. For example, clicking the Yuzhou-deep-day intersection, inquiring all adjacent intersections of the Yuzhou-deep-day intersection, only having the Yuzhou-Taishan road in the east direction, initializing controls of the two intersections on the interface, writing intersection names into the controls, and not processing the controls in other directions.
The interface then subscribes to all phase real-time light states of the signal machine for 5 intersections (if there are no intersections in a certain direction, it does not process) for the intersection and its southeast, northwest. When the interface receives the phase data transmitted by the signal machine, the phase data is analyzed, and real-time light states of 12 phases including east (left, straight and right), west (left, straight and right), south (left, straight and right) and north (left, straight and right) are displayed according to lanes. The remaining seconds of each phase (i.e., countdown) are represented in numerical size, and the numerical colors (red and green) represent whether to go (red and green).
And 8: display of phase correlation data:
the interface inquires the phase flow of each phase of all intersections, the release time of the phase in one period and the variation of the release time of the phase in the period and the previous period every 10s, and displays the data on the lane representing the phase. The display state of each data is detailed in step 3.
And step 9: display of road segment associated data:
the interface queries the occupancy of the link detector and the occupancy of the overflow detector for each link of all intersections every 10s and displays the data at the position representing the link. The digital color of the occupancy of the link detector and the overflow detector is determined according to the range of the occupancy, and is detailed in step 5.
Step 10: drainage, current limiting and forbidden control:
when lo<t1When the current is needed, no treatment is carried out; when lo is not less than1And carrying out current limiting control on the upstream crossing and carrying out drainage control on the downstream crossing. When oo< t2When the current is needed, no treatment is carried out; when t is2≤oo< t3Then, carrying out current-limiting control on the upstream crossing and carrying out drainage control on the downstream crossing; when oo is more than or equal to t3And in time, forbidding entrance control is carried out on the upstream intersection, and drainage control is carried out on the downstream intersection.
