Much of the work previously undertaken by the County Council started from the premise that a bypass of Ormskirk was the most appropriate solution. However, the scale and likely cost of a bypass effectively rule out any detailed development work within the lifetime of the current Local Transport Plan (LTP). The rationale for this study is therefore to re-examine the problems and issues associated with the highway network in West Lancashire, with a view to determining whether there are alternative (lower cost) measures that the County Council and other agencies could implement to mitigate identified problems and issues. The purpose of this report is to summarise the outcome of the Data Collection and Problem Identification Stage (Stage 1) of the M58 to Southport Corridor Study. The data collection and analysis process has focused on the strategic issues affecting the M58 to Southport corridor and the associated issues affecting the surrounding transport network. A wide range of different types of data have been collected, analysed and presented using the Geographical Information System (GIS) software ArcGIS. The GIS database which has been compiled has enabled an efficient and comprehensive analysis of the M58 to Southport corridor as well as the associated impacts on the surrounding transport network. A review has been undertaken of the Ormskirk SATURN Model which was developed in 2005 to investigate the impact of a potential bypass of Ormskirk. In summary, the review examined survey data, model validation, traffic flows, trip movement analysis, forecasted traffic flows on the proposed bypass and analysis of journey times in Ormskirk town centre. A technical paper outlining the conclusions of this review has been produced (Ormskirk SATURN Model Review, Jacobs, February 2012) and is available upon request from the County Council. Previous studies undertaken by the County Council and West Lancashire Borough Council to investigate the issues surrounding Ormskirk have been reviewed and summarised. The conclusions drawn in this Stage 1 Report build upon the findings of the previous studies which have been undertaken.
