Mott MacDonald providing strategic network analysis tool in Southampton, UK

Mott MacDonald is working with Southampton City Council’s prestigious ROMANSE service (ROad MANagement Systems Europe) in developing an Offline Analysis Database (OAD). This database will assess the impact that changes in traffic demand, strategic network management and improvements in Intelligent Transport Systems (ITS) have on the movement of traffic through urban areas, helping to better understand the strategic network.

Traffic flow and journey time data obtained from carriageway sensors and Automatic Number Place Recognition (ANPR) cameras will be stored in the OAD along with car park occupancies, pollution levels, signal timings, traffic incidents, road works and events. The OAD will make this historical data available in an easily accessible format so that Southampton ROMANSE can perform a wide range of analysis to help identify potential issues and assist in the strategic management of the highway network.

The OAD includes many powerful analysis features including an area of interest function which identifies local situations that may have influenced traffic flows at the time it was recorded, such as variable message sign settings and traffic events. The system has been designed to allow ROMANSE access to additional streams of data and forms of analysis not previously available in OAD.

Southampton ROMANSE has evolved through close collaboration between Hampshire County Council and Portsmouth City Council, who collectively aim to provide informed travel choice by influencing travel behaviour through the provision of real time traffic and travel information and the use of modern traffic management techniques. Mott MacDonald ITS experts have worked closely with ROMANSE on a number of exciting ITS projects over the last three years including assessing network corridor capacity and providing traffic signal design services.

Mott MacDonald project director, Andrew Walsh said, “Mott MacDonald has a wealth of experience in collecting, analysing and utilising traffic data to improve travel conditions across all road networks and we are pleased to be able to support Southampton ROMANSE in achieving their objectives to optimise network performance by bringing our expertise to this project.”

Martin Wylie, traffic signals engineer at Southampton ROMANSE added, “The OAD looks especially interesting due to its graphical representation of multiple data streams allowing a snap shot of traffic influences to be generated for a specific time period which can then be further analysed should the visualisation indicate the need. Data input into the OAD will benefit from an automated validation process which will increase confidence in the historical data profiles and identify periods of abnormal network activity prompting further investigation.”
