Suggestions on alleviating morning rush hour congestion in Guanhuayuan Community

I am the owner of Guanhuayuan and have lived in the community for 2 years. I personally realize that the morning rush hour is getting more and more congested, and I have a suggestion that can alleviate the congestion without too much resources as follows:

1. Cars leaving the south gate of the community (Lindingsi Road) are not allowed to turn left. If you want to turn left, you should come out of the east gate of the community, take the Tang Lu Road auxiliary road, and then turn left or right from the fixed way.

2. It is forbidden for carts to enter from the east gate of the community, otherwise they can only leave from the east gate during the morning rush hour (7-9).

3. Adjust the order of traffic lights at the intersection of main and auxiliary roads of Litang Road. So as to form the next driving cycle.

Take 8 minutes as a cycle (at present, the traffic flow of Litang Road and Dingsi Road is the same, and the traffic flow of left-turn traffic is half of that of through traffic to allocate time, and the real-time allocation ratio can be calculated from the traffic flow ratio in all directions).

① Go straight north-south on the main road of Litang Road+turn left120s.

② Turn left on the main road of Litang Road for 50 seconds?

③ The main route of Litang Road turns left from north to south+the waiting area turns left from south to north 10 second.

④ The main and auxiliary routes of Litang Road turn left from north to south+the auxiliary roads go straight for 60 seconds.

⑤ Go straight west+turn left, turn left at Litang Road North to Funan Road (then turn right and go straight) 120 seconds. Remove the median from the auxiliary road of Litang Road to the main road (between ① ② and ③ ④ below), and change the lane to tidal lane for vehicles that need to turn left at the auxiliary road of Litang Road.

6. Go straight on Ding Si Road West+turn left 120 seconds?

After adjustment, take 8 minutes as a cycle (the cycle can also be set to 4 minutes):

The main road of Litang Road is a through-train vehicle, which can pass in 2 minutes.

On the main road of Litang Road, vehicles turning left from south to north can pass for 50 seconds, and vehicles turning left from north to south can pass for 2 minutes.

Litang road auxiliary road, straight and left-turning vehicles can pass for 3 minutes.

The two-way straight and left-turn vehicles on Dingsi Road will pass for 2 minutes respectively.

Analysis on the causes of current community congestion

In addition to the large traffic volume, the main reasons leading to traffic congestion in the community are:

1. There are too many cars coming out of the south gate of the residential area and you need to turn left (cars that have to go in the south, east and north directions). When the vehicle needs to turn left and not enter the eastbound traffic flow of Dingsi Road, it will block the westbound traffic of Dingsi Road (even if the driver wants to make way, there is no way to make way).

2. When there are about 30 vehicles heading west, the main and auxiliary roads of Litang Road will be blocked, not only the vehicles heading south with high probability, but also the vehicles heading north sometimes. Cars (many carts) who want to turn right into Dingsi Road and then go west on Litang Road choose to enter from the east gate of the community and then go out from the south gate of the community, and turn right through the interior of the community, which leads to an increase in vehicles in the community and a vicious circle.
