CVE30003 Transport Engineering Assignment Intersection Performance Analysis and Geometric Design Submission Due: 5 pm Tuesday, 12 May 2015 Work in groups of 3 students MARKS Traffic performance analysis: 10 marks Geometric design using AutoCAD: 7 marks Quality of the written report: 8 marks Total = 25 marks Pound Road / Shrives Road, Hampton Park BACKGROUND The intersection of Pound Road and Shrives Road is in a residential part of Hampton Park in Melbourne's outer south east suburbs - Melway reference 96J7. It is a "Y" shaped intersection currently controlled by Give Way signs. VicRoads is considering whether to upgrade the intersection to a roundabout or traffic signals. There are currently long delays in peak periods and there have been a few crashes since 2008. YOUR TASKS The VicRoads senior traffic engineer responsible for this area has asked you for a report with sufficient analysis of different forms of intersection control for this site. You have been asked to assess the traffic and safety performance and consider all other matters relating to the choice of intersection control and write a report justifying your recommended treatment. Provide a functional geometric design layout plan of the intersection for your recommended treatment - either traffic signals or a roundabout. METHOD You will use the SIDRA INTERSECTION software in the two Computer Laboratory classes on 22/23 April and 29/30 April. Use SIDRA to analyse the following: · the existing intersection with Give Way signs, with existing (2013) traffic volumes, · a roundabout, · traffic signals. For a comparative check, also calculate the capacity and degree of saturation of the main movements at the existing unsignalised intersection, using manual methods . You will need to analyse the intersection for the morning and afternoon peak hourly volumes. CVE30003 Assignment Page 1
For the traffic signals case, you need to analyse several options to determine the most efficient geometry, phasing and type of right turn control that gives the best intersection performance. Right turn movements may be fully controlled, partially controlled or filter only. You must present the SIDRA outputs for at least 3 sensible variations in the Appendices to your report. Generally, assume that parameters are the same as SIDRA defaults. However, these may be modified if this would result in a more realistic assessment. BACKGROUND INFORMATION The following information is provided: 1. An aerial photo File: Pound Shrives Aerial.pdf . The surrounding land use can be seen in the photos. There is a petrol station and 7-11 in the south-east corner. More information on the surrounding area can be found from a site visit, from street directories or on-line aerial photographs. . On the north side of the intersection, there is a land reservation which would allow you to acquire the front part of the adjoining properties. This allows the property boundary to be extended 20 metres to the north. 2. Traffic volumes from 2013 File: Pound Shrives Turning Movement Counts 2013.xlsx · These counts include heavy vehicles, pedestrians and bicycles. · In these outer suburbs,
