Methodology for evaluating highway-railway grade separations Schrader, Michael H ; Hoffpauer, John R

By: Schrader, Michael HContributor(s): Hoffpauer, John RPublication details: Transportation Research Record, 2001Description: nr 1754, s. 77-80Subject(s): USA | Interchange | | Method | Location | | Decision process | Accessibility | Noise | Delay | Land use | Safety | J06 | 821Bibl.nr: VTI P8167:1754Location: Abstract: To better allocate scarce regional transportation resources when considering the construction of grade-separated highway-railway crossings in Central Arkansas, Metroplan, the Metropolitan Planning Organization, created a methodology to provide a consistent quantitative evaluation of potential locations. This methodology considered use of seven quantitative factors: noise, community cohesion, delay, accessibility, connectivity, geographic distribution, and safety. Each factor yielded a value between 0 and 1, which allows an equally weighted comparison between the different factors as well as a net sum of all factors. The new result, then, is an aggregate value that can aid in the evaluation and prioritization of potential highway-railway grade separation locations.
