You must have encountered such a situation. When you return from shopping in a shopping mall with a full load and drive the car out of the underground garage, the steep slope of the exit will make you feel uncomfortable, especially for novices, it is a torture and test, because the steep slope of the exit may cause the car to stall or slip Slope, etc., are prone to accidents. What are the current problems in the design of underground parking lots?
One is that the entrances and exits have a steep slope, and the roads are narrow and curved. Let's talk about the downhill gradient first. Generally, the channel gradient of the underground garage should be below 15%. Too large is unreasonable and violates the regulations. In order to accommodate more vehicles, many underground garages design the driveway to be very short without buffering, so the slope is very high. In addition, the narrow lanes and winding roads will not only scare novices, but also veterans.
The second point is that some underground parking lots set guard booth charges on slopes, which is very unreasonable. Because of this setting, drivers and friends have to park on the slope to pay the fee, which is prone to slipping, and it is also easy to cause the car to stall and need to start again, which causes inconvenience to the driver and also affects the speed of traffic.
For the above two points, we suggest here that the gradient of the entrance and exit of the underground parking lot should be controlled below 12%, which can be suitable for adding some gentle slope sections, and the guard booth fee should not be set on the slope.
