Urban Roadway At-grade Intersection Design Standardin Chongqing(DBJ 50/T178—2014) has been implemented since May 1st, 2014, which provides the guidance for urban intersections design in Chongqing. This paper explains the principles of the standard, including public transit priority, and integra-tion of planning, design and management. The paper summarizes the innovative ideas in the specification as follows: adopting context sensitive design standard according to the environment and terrain of urban built-up area to avoid excessive construction, identifying the influential factors on the selection of intersec-tion layout and the method, adjusting the standard of stopping sight distance at intersections, and etc. Fur-thermore, the specification also defines the designed vehicle type, pedestrian crossing facilities, turning ra-dius of curb, obstacle-free crossing facilities, and length of bus stops in detail.
