Improving Safety of Rural Intersection with Approaching Reverse Curve
This paper exhibits the safety improvement study for the reverse curve and unsignalized stop-controlled intersection at Regional Road 14 and Young Street in the Niagara Region. Regional Road 14, also known as Thirty Road, is a major road running north/south in the Town of West Lincoln. Under current conditions, many collisions have been reported at the intersection of Thirty Road and Young Street and along the reverse curve portion of Thirty Road itself. With a projected annual growth rate of 5%, traffic volumes travelling in the direction of Smithville are expected to increase by 2041 drastically. This study aims to evaluate viable design alternatives and further develop the selected improvement that can safely accommodate the projected 2041 traffic volumes for Thirty Road at Young Street. Data provided by the Niagara Region for analysis includes existing geometric conditions, utility locates, 2019 collision data, 2011 baseline volumes, and forecasted volumes for the horizon year 2041. The alternatives presented are realignment of the reverse curve with a roundabout, signalized intersection, or all-way stop intersection. The evaluation criteria used in the analysis are as follows: safety, level of service, cost, and environmental impact. A ranked system in tandem with weighted criteria was used to assess the level of influence of the alternatives, with the results then weighted using the final evaluation model. The evaluation showed that the alternative with a roundabout was the best. Surrounding utilities and other constraints were considered when developing detailed designs of the improved realignment and intersection using AutoCAD Civil 3D.
