Weave Analysis

Weaving sections are common design elements on freeways, especially near on and off ramps and freeway to freeway connectors. When the traffic demands exceed the capacity at a weaving section, congestion occurs, affecting the operation of the entire freeway section. Traffic operational problems also may exist at weaving areas even when traffic demands are less than capacity because of the complexity of vehicle interactions, resulting in traffic delays and potential safety problems. This study evaluates existing weave analysis methodologies against field data to determine which method is the most appropriate for design and future analysis of freeway weaving sections in California.
