The benefit of the ARCADY-Autodesk Vehicle Tracking link is that, for the first time, the roundabout designer can see both geometric and performance data at the same time.
This encourages a much faster design cycle than using traditional methods. As the roundabout is created, Autodesk Vehicle Tracking calculates and sends the main roundabout geometries to ARCADY. ARCADY receives and displays the data read-only to indicate that the data is being provided by Vehicle Tracking. ARCADY then performs a full model run and passes back the main results (Queue, Delay, RFC & LOS) which are displayed in Vehicle Tracking. Note that Vehicle Tracking does not manipulate the data received from ARCADY in any way.
Users may enter traffic and other non-geometric data in ARCADY the usual way and these will obviously affect the results passed back to Vehicle Tracking.
The link is automatically started by Vehicle Tracking if necessary and creates and opens data files as required. The ARCADY data file is created in the same directory as the Vehicle Tracking file and has the same root name, e.g. if you invoke the link from Vehicle Tracking using a data file called EXAMPLE.DWG, it opens or creates (if necessary) a file called EXAMPLE.ARC8.
When the Vehicle Tracking file is saved, Vehicle Tracking tells ARCADY to save the corresponding ARCADY file so that they remain synchronised.
