The relationship between ramp management and freeway management

This sample was created on the base of the puzzles diagram from the webpage "Ramp Management and Control" of US Department of Transportation Federal Highway Administration website. [ops.fhwa.dot.gov/publications/ramp_mgmt_handbook/brochure/brochure.htm] "What is Ramp Management? Ramp Management is the…“application of control devices, such as traffic signals, signing, and gates to regulate the number of vehicles entering or leaving the freeway, in order to achieve operational objectives”. Ramp Management Strategies. There are four accepted and proven strategies to manage ramp-based traffic: (1) Ramp Metering - The use of traffic signal(s) deployed alongside a ramp to control the rate at which vehicles enter a freeway facility. (2) Ramp Closure - Ramp closure involves the use of gates, barriers or cones to restrict vehicle access to a ramp. Closures can be permanent, temporary, or scheduled. (3) Special Use Treatments - Special use treatments give “special” consideration to a vehicle class or classes to improve safety, improve traffic conditions, and/or encourage specific types of driving behavior. (4) Ramp Terminal Treatments - Ramp terminal treatments are solutions to problems that occur at or near ramp/arterial intersections. ... The Relationship between Ramp Management and Freeway Management. Ramp management is a single function that typically falls under the freeway management umbrella. Ramp management elements work with other elements of freeway management (e.g., HOV Treatments and Incident Management) to deliver freeway management system goals and objectives. This relationship can be likened to puzzle pieces with ramp management representing one of the pieces that need to collectively come together to ensure successful operations. In addition to freeway management, ramp management should also be coordinated closely with arterial management, transit management, and other parts of the overall surface transportation system."
