<strong>Sensys</strong> <strong>Stud</strong> <strong>Trial</strong><br />
4.2 Data Collection Methods<br />
SCATS<br />
Data was collected from SCATS as a comparison between Inductance Loops already installed<br />
under the TDM project and the <strong>Sensys</strong> studs. The <strong>Sensys</strong> <strong>Stud</strong>s were installed in the road a<br />
few metres before the inductance loops to minimise the possibility of variations between the two<br />
detection systems. By collecting data in SCATS a direct comparison of the performance of the<br />
inductive loops vs. <strong>Sensys</strong> studs could be made in a real world environment.<br />
SCATS data was collected every 30 seconds over a 24hr period and an analysis was made for<br />
Peak traffic times and Off Peak traffic times for Friday 4 th July 2008.<br />
Using the SCATS connection the following data was compared between the Inductance Loops<br />
and <strong>Sensys</strong> <strong>Stud</strong>s<br />
• Occupancy<br />
• Count<br />
The data for the Occupancy analysis can be found in Appendix 3.<br />
TrafficDot<br />
For the first week of the trial the TrafficDot software was left to run and collect data. (Note: The<br />
inductance loop for lane one at this time was not connected as it had been milled out by<br />
external parties)<br />
The Occupancy data collected for period 19/06/2008 – 27/06/2008 is shown in Appendix 1.<br />
By installing 2 sensors per lane TrafficDot was able to produce the average speed readings for<br />
each lane.<br />
The average speed data collected for period 19/06/2008 – 27/06/2008 is shown Appendix 2.<br />
