Abstract: We addressed the channelization key parameters at an urban road intersection to improve scientificity and rationality for the design of channelization at an urban road intersection. We also presented a length calculation model for its intersection stretching and transition segments for the traffic safety and the riding comfort. The intersection at Changcheng and Mudan roads is selected to prove the method. Results show that the method is practical and referential, and can provide theory fundamentals for advanced research on channelization design at a skewed intersection.

Key words: intersection channelization, stretching segment, sidewalk, transition segment
