WSDOT Design Manual M Page 1310-1 July 2017 Chapter 1310 Intersections General Design Considerations Design Elements U-Turns Intersection Sight Distance Signing and Delineation Procedures Documentation References General Intersections are a critical part of Washington State Department of Transportation (WSDOT) highway design because of increased conflict potential. Traffic and driver characteristics, bicycle and pedestrian needs, physical features, and economics are considered during the scoping and design stages to develop channelization and traffic control to provide multimodal traffic flow through Intersections . See chapters in the 1100 series for instruction on multimodal practical design, including identifying project needs, context, design controls, modal performance, alternatives analysis, and design element dimensioning. This Chapter provides guidance for designing Intersections , including ramp terminals. Refer to the following chapters for additional information: Chapter Subject 1103 Design controls 1106 Design element dimensions 1230 Geometric cross section 1300 Intersection control type 1320 Roundabouts 1330 Traffic signals 1340 Driveways 1360 Interchanges 1510 Pedestrian facilities 1520 Roadway bicycle facilities For assistance with intersection design, contact the Headquarters (HQ) Design Office.
