What are the design specifications for turning areas?
1 Answers
For dead-end driveways exceeding 35m in length, a turning area must be provided. The driveway length should not exceed 120m, and a turning area of no less than 12m×12m should be established. For high-rise buildings, this should be no less than 15m×15m. Additional information: Large vehicle areas: The turning area for large fire trucks should not be less than 18m×18m. When setting up a turning area at the end of a road, its size should be determined based on the vehicle's minimum turning radius and road width. A minimum turning radius of 6m (inner diameter) for fire lanes meets the minimum turning requirements for fire trucks. Requirements: The road surface of fire lanes, operational areas for firefighting, and the underlying pipelines and culverts must be able to withstand the pressure of large fire trucks. Fire lanes can utilize traffic roads but must meet the requirements for fire truck passage and parking.
