Operating InSync

Data and Reporting

InSync records a tremendous amount of data. Second-by-second details about what the system detected and its past operations are available in searchable, exportable reports. This data can be very useful in determining trends, reviewing what happened at an intersection at a particular moment in time or evaluating InSync’s performance.


The WebUI offers a Statistics Database. The operator can submit a query of InSync’s statistics by entering the date range, time range and type of data he/she would like to see (vehicle counts, stop delay or level of service). The WebUI can generate the statistics report in four different ways – as a table or graph displayed in a web browser, or as a text or comma-separated values (.csv) file for download.

Vehicle Count Graph

Because InSync is driven by rich data, the data collected can also be analyzed for trends. Data for volume, delay and level of service can be viewed for any timeframe with a few clicks.

History Viewer

The WebUI also offers a History Viewer. This allows the operator to see precise historical phasing and intersection information for particular days and times of day. The data is available to be displayed graphically within the web browser or as a .csv file for download. The History Viewer uses icons to show exactly which movement InSync served at particular times of day, the duration of the movement and other conditions at the intersection at that time, such as queue lengths and wait times.

At the global level, the operator can see coordinated movements served and any adaptive qualities applied to the coordinated movement such as whether the tunnel was truncated due to low demand, or whether the period length (time between tunnels) changed. Pedestrian call and preemption data are also available, allowing the operator to see and determine the reason for InSync’s decisions.

Archiving Data

The WebUI automatically stores traffic counts, delay and level of service data for 30 days. Using InSync’s archival mechanism, which is a simple, automated FTP process, data can be transmitted to another storage location to store an infinite amount of data. The data can be saved to a file on the traffic practitioner’s personal computer if desired. In general, the data for each day’s worth of traffic is very small.

“With our small staff we were not always able to retime traffic signals as often as we would like. On these 26 intersections, timing plans are now a thing of the past, saving valuable employee time.”
