Typical Two RV Dump Station Layout Figure 1030-3 Design Manual Safety Rest Areas and Traveler Services November 1999 Page 1030-5 Design Manual Weigh Sites May 2000 Page 1040-1 1040 Weigh Sites median The portion of a divided highway separating the traveled ways for traffic in opposite directions. outer separation The area between the outside edge of traveled way for through traffic and the nearest edge of traveled way of a frontage road. roadway The portion of a highway, including shoulders, for vehicular use. A divided highway has two or more roadways. sight distance The length of roadway visible to the driver. shoulder The portion of the roadway contiguous with the traveled way, primarily for accommodation of stopped vehicles, emergency use, lateral support of the traveled way, and use by pedestrians and bicycles. static scale A scale that requires a vehicle to stop for weighing. stopping sight distance The sight distance required to safely stop a vehicle traveling at design speed. traveled way The portion of the roadway intended for the movement of vehicles, exclusive of shoulders and lanes for parking, turning, and storage for turning. usable shoulder The width of the shoulder that can be used by a vehicle for stopping. weigh in motion (WIM) A scale facility capable of weighing a vehicle without the vehicle stopping. 1040.03 Planning, Development, and Responsibilities The WSP works with the WSDOT’s Planning and Programming Service Center to develop a prioritized list of weigh facility needs for each biennium. The list includes: • New permanent facilities • New portable facilities • New shoulder sites 1040.01 General 1040.02 Definitions 1040.03 Planning, Development, and Responsibilities 1040.04 Permanent Facilities 1040.05 Portable Facilities 1040.06 Shoulder Sites 1040.07 Federal Participation 1040.08 Procedures 1040.09 Documentation 1040.01 General Truck weighing facilities are needed to protect state highways from overweight vehicles, to provide for vehicle safety inspection, and to provide a source of data for planning and research. The development, construction, and maintenance of these facilities is a cooperative effort between the Washington State Department of Transportation (WSDOT) and the Washington State Patrol (WSP). 1040.02 Definitions Commercial Vehicle Information Systems and Networks (CVISN) A network that links intelligent transportation systems (ITS) to share information on commercial vehicles. When in operation at a weigh site it can enable commer- cial vehicles to clear the facility without stopping. decision sight distance The sight distance required for a driver to detect an unexpected or difficult-to-perceive information source or hazard, interpret the information, recognize the hazard, and select and complete an appropriate maneuver safely and efficiently. functional classification The grouping of streets and highways according to the character of the service they are intended to provide. (See Chapter 440.) frontage road An auxiliary road that is a local road or street located beside a highway for service to abutting property and adjacent areas and for control of access. lane A strip of roadway used for a single line of vehicles.
