Systems and methods are provided for prioritizing traffic information and broadcasting the traffic information in a prioritized order. The method generally comprises receiving data regarding traffic conditions on various roads, wherein each road can be characterized as being a major, medium, or minor road. In one approach, traffic data regarding major roads are broadcast to vehicles first, followed by traffic data regarding medium roads, while traffic data regarding minor roads are either broadcast last or not at all, depending on the traffic information handling capacities of the vehicles and the traffic information system in general.

Some embodiments provide a navigation application with a novel declutter navigation mode. In some embodiments, the navigation application has a declutter control that when selected, directs the navigation application to simplify a navigation presentation by removing or de-emphasizing non-essential items that are displayed in the navigation presentation. In some embodiments, the declutter control is a mode-selecting control that allows the navigation presentation to toggle between normal first navigation presentation and a simplified second navigation presentation, which below is also referred to as a decluttered navigation presentation. During normal mode operation, the navigation presentation of some embodiments provides (1) a representation of the navigated route, (2) representations of the roads along the navigated route, (3) representation of major and minor roads that intersect or are near the navigated route, and (4) representations of buildings and other objects in the navigated scene. However, in the declutter mode, the navigation presentation of some embodiments provides a representation of the navigated route, while providing a de-emphasized presentation of the roads that intersect the navigated route or are near the navigated route. In some embodiments, the presentation shows the major roads that are not on the route with more emphasis than minor roads not on the route. Also, in some embodiments, the presentation fades out the minor roads not on the route more quickly than fading out the major roads not on the route.

The present application discloses a video-based main road cooperative signal machine control method, which includes: installation of video detectors at each intersection of the main road; data acquisition and communication of a single intersection; data acquisition and storage of multiple intersections; data processing of the main road coordination signal control; signal command release service and signal light control. The application adopts active video detection technology, which can accurately detect the traffic state of multiple intersections of the main road, formulate an optimized signal control scheme, provide optimal decision and emergency plan for the control of traffic light of the main road, improve the traffic efficiency of intersections and effectively alleviate traffic congestion on trunk roads.

The invention discloses a multi-fork intersection structure and an upper-road entry signal-control method. The upper-road entry signal-control method comprises arrangement of an intersection and a region of each road, and a signal-control method for the intersection. For the intersection, four primary roads are selected as a crossroad and adopt a turn-left control method; a secondary road adopts an upper-road entry design and the signal-control method, is provided with a first exit region, a second exit region, a third exit region, an entry waiting region and an exit lane, so that the secondary road can be integrated into the turn-left control method of the crossroad; the secondary road can be directly connected with each primary rod. With adoption of the multi-fork intersection structure and the upper-road entry signal-control method provided by the invention, the number of phases of the intersection can be reduced, to improve the efficiency of a multi-fork intersection, reduce the delay, prevent vehicles from indirect left turning, and improve the traffic capacity.

The invention discloses a composition and structure of a three-way intersection and a lane change control method of the three-way intersection. When a person stands on one side of a north road of the three-way intersection and faces the three-way intersection, a left-turning to-be-turned area is arranged on the left side of the north road, left-turning vehicles of the north road are stopped and wait for running, an exit lane is arranged on the right side of the left-turning to-be-turned area, and left-turning vehicles of a west road or right-turning vehicles of an east road are driven out. A safety island is arranged in the middle of one side of the north road of the three-way intersection, and only one main zebra crossing is arranged to stretch over the main roads. The lane change control method of the three-way intersection includes the steps that when go-straight green lights of the east road and the west road are turned on, the left-turning vehicles from the north road are driven to the left-turning to-be-turned area of the north road to be stopped, and the left-turning vehicles from the west road are stopped in a left-turning to-be-turned area of the west road. When go-straight red lights of the east road and the west road are turned on, the vehicles in the left-turning to-be-turned area of the north road turn left to the east, meanwhile, the vehicles in the left-turning to-be-turned area of the west road turn left to the north, and pedestrians cross the east and west main roads on the main zebra crossing.

Provided is a overloaded control system for vehicles in a scenic spot. The system comprises a statistic system for the vehicles placed at the boundary of the scenic spot utilizing for counting the number M1 of the motor vehicles in the scenic spot at that time; a control center system utilizing for receiving the motor vehicles number M1. A control signal is sent to traffic light controllers placed on the main road of the scenic spots and at the boundary of the scenic spot within 20km when M1 exceeds the maximum capacity threshold K of the vehicles in the scenic spot. In addition to the signal sent, the time of red lights along the scenic spot is prolonged while the time of the green lights along the scenic spot remains constant. By counting the number of motor vehicles in the scenic area and regulating the traffic light, the invention automatically delays the speed of the motor vehicle leading to the scenic area, and prevents the motor vehicle from pouring into the scenic area at short time, thus causing hidden trouble in safety. The present invention also through the statistics of the number of motor vehicles outside a scenic, scenic forecast after a certain period of time the number of motor vehicles, according to the predict results, regulate the corresponding mode of traffic lights, more precise and flexible.

The invention discloses a multi-fork intersection structure and a lower-road entry method. The lower-road entry method comprises arrangement of an intersection and a region of each road, and a signal-control method for the intersection. For the intersection, four primary roads are selected as a crossroad and adopt a turn-left control method; a south road is provided with an entry waiting region and the like; a secondary road adopts a lower-road entry design and the signal-control method, so that the secondary road can be integrated into the turn-left control method of the crossroad; the secondary road can be directly connected with each primary rod. With adoption of the multi-fork intersection structure and the lower-road entry method provided by the invention, the number of phases of the intersection can be reduced, to improve the efficiency of a multi-fork intersection, reduce the delay, prevent vehicles from indirect left turning, and improve the traffic capacity.
