specific Embodiment approach 1
[0020] Specific implementation manner one: such as figure 1 As shown, a pre-signal control method for turning left and right of a bus at an intersection includes the following steps:
[0021] After the left-turn lane of the bus is set to the right, the right-most lane only allows right-turning vehicles, left-turning buses and through vehicles to pass. The right-turning vehicles are under the control of the main and pre-signal, and the traffic rules are consistent with the through vehicles, so the following content The right-turning vehicles will not be described separately, and the two will be collectively referred to as straight-going vehicles.
[0022] Considering the road speed limit value and the actual traffic facilities setting restriction conditions to obtain the distance L, set a lane change marking line in the rightmost lane and the adjacent straight lane at a distance from the stop line L, and set a traffic sign and Pre-signal system; then, according to the vehicle size, ...
specific Embodiment approach 2
[0028] Specific embodiment two: this embodiment is different from specific embodiment one in that: in the step one, it specifies the specific process of the pre-signal control of the vehicle running direction on the rightmost lane and the specific process of the vehicle running rules on the adjacent straight lanes of the rightmost lane for:
[0029] When the pre-signal straight green light is on, the straight vehicles in the straight lane adjacent to the rightmost lane will line up before the stop line, or change to the rightmost lane before the lane change marking is prompted, and be in the rightmost lane There is a queue in the area between the parking line and the left-turn bus waiting area; the left-turning bus stops in the left-turn bus waiting area and waits; when the pre-signal bus turns left green light is on, it prompts the rightmost lane to turn left in the bus waiting area The left-turning bus in the inside starts and passes through the intersection; straight vehicles ...
specific Embodiment approach 3
[0031] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the specific process of coordinating the timing of the pre-signal according to the timing of the main signal at the intersection in the second step is:
[0032] The pre-signal is divided into straight-going vehicle pre-signal light and left-turn bus pre-signal. Both the straight-going vehicle pre-signal light and the left-turn public transport pre-signal include two colors of red and green, and are divided into two-phase control: ① Pre-signal left-turn bus green light + pre-signal Straight red light ②Pre-signal go straight green light + pre-signal turn left to the red bus light, the main signal and pre-signal cycle duration are equal;
[0033] Before the main signal turns left and the green light ends, the pre-signal turns left before the green light of the bus ends, and the pre-signal goes straight green (controls all straight-going vehicles) lights are on to prevent the main ...
