Highway-rail Grade Crossing Surfaces
Author: Hoy A. Richards
Publisher: Transportation Research Board
ISBN: 9780309061063
Category : Technology & Engineering
Languages : en
Pages : 68
Book Description
This synthesis will be of interest to state and local highway personnel who are responsible for the design, construction, and maintenance of road surfaces and to railroad personnel with similar responsibilities associated with highway-rail grade crossings. It will also be of interest to manufacturers and suppliers of pavement and track materials for crossings. It presents information on the current practices related to highway-rail grade crossing surfaces, including the design and selection of crossing surface materials. This report of the Transportation Research Board describes the various types of highway- rail crossing surfaces, and the issues related to design, operation, and maintenance. Design elements include intersection geometry; drainage; special users, such as bicyclists; and descriptions of failures and their causes. Information is presented on crossing material selection factors, including life-cycle costs and on state practices in selection. Funding issues are also discussed.

A Recommended Procedure for Timing Design at Highway-railroad Grade Crossing with Four Quadrant Gates
Author:
Publisher:
ISBN:
Category : Highway-railroad grade crossings
Languages : en
Pages :
Book Description
Four-quadrant gate warning systems have been devised to enhance safety at highway-railroad grade crossings. The use of four gates instead of two provides a "closed" system that reduces the opportunity for motorists to enter the crossing zone improperly by weaving around the gates. It is clearly necessary to provide adequate time for all vehicles to clear the track area. However, if the exit gate descent is delayed longer than necessary, the crossing will remain open to violations and the purpose of the four-quadrant system will be defeated. There is a tradeoff between the two possible hazards created by exit gate delay times that are too short or too long. Ideally, an optimal value that would minimize the total hazard should be sought. A timing and analysis model was developed as a product of the research study described in this report. The model is based on the rationale that the timing must accommodate the "foreseeable worst-case scenario", which is defined by the combination of circumstances that will leave a vehicle exposed within the crossing zone for the longest time.

Railroad - Highway Grade Crossing Handbook
Author: United States. Federal Highway Administration. Office of Engineering. Railroads and Utilities Branch
Publisher:
ISBN:
Category : Railroad crossings
Languages : en
Pages : 260
Book Description
This handbook briefly describes how growth of railroads and highways resulted in a proliferation of grade crossings and then discusses the variety of methods developed to warn pedestrians and vehicles of approaching trains. It is aimed primarily at providing railroad, state and municipal personnel with information which can help in cooperative efforts to improve grade crossing safety and efficiency. The book describes conditions and requirements at crossing; facilitates understanding of the elements of crossing systems; provides a compendium of existing grade crossing technology; serves as a guideline to aid in implementing improvements to grade crossings; aids in understanding and applying new technology; and serves as a basic text for training programs.
