1240/5(4980)

WRITTEN QUESTION TO THE MINISTER FOR TRANSPORT AND TECHNICAL SERVICES BY THE DEPUTY OF ST. MARY

ANSWER TO BE TABLED ON TUESDAY 1st DECEMBER 2009

Question

"Can the Minister advise the Assembly what information, if any, is recorded about each road accident in the Island, how this data is held, the categories and columns used (assuming it is in spreadsheet form), and if not in spreadsheet form, how the data is made collatable?

Can the Minister further advise what analysis is performed on the data, and whether any form of report is generated from the data, and at what intervals?"

Answer

Road traffic collision data is collected, collated and recorded by the Home Affairs Department who annually pass the data (excluding the registration numbers of vehicles) to the Transport and Technical Services Department (TTS). The Home Affairs Department has changed its system but the latest data incorporated all the fields attached at Appendix A to this answer.

Annually, TTS also plots all reported injury accidents onto mapping layers using the States of Jersey GIS Mapping facilities. The map plots are used on a day to day basis by various members of the Department's Traffic Engineering team as and when issues arise, planning applications are reviewed or various traffic management proposals are investigated or reviewed. The data also provides information to help the TTS assess where and why road accidents occur.

Officers at TTS analyse the data to provide the key performance indicators for the States Annual Performance Report as detailed in the table below:

ROAD TRAFFIC COLLISIONS 2005 - 2008

IMPORTANT NOTE

Prior to March 2008, road traffic collision statistics were subject of a separate paper form submitted by the investigating officer.

In March 2008, road traffic collision data began to be gathered through the VIEWPOINT recording system, which facilitated closer monitoring of the accuracy of records and also eliminated the possibility of paper forms being lost. It is likely that some of the increase shown in 2008 is due to the introduction of more accurate recording processes in States of Jersey Police
