Selecting an Operating Mode
Use provided Windows Configuration Utility to set an appropriate mode of operation as
recommended in
Operating Mode section
.
Selecting Clutter Time Constant and Performing Clutter Initialization
Use provided Windows Configuration Utility to set clutter time constant (CTC). Clutter
time constant should be 5-10 longer than the maximum expected duration of the stopped
traffic. For example if a vehicle stops in front of the traffic light for a maximum of 1
minute, CTC should be set to 5-10 minutes. After the time constant is set, wait for clear
road and initialize clutter map. Clutter map initialization takes 15 seconds. Occupancy
should be low during this time. Clutter map initialization is not absolutely required.
Without initialization it will take the radar about ten CTC to initialize the clutter map on
its own and start operating normally but this delay will occur after
every power cycle
.
Do not re-initialize clutter map on a regular (e.g. every hour) basis as it is written to
internal FLASH memory that will wear out after 10000 writes.
Defining Lanes
Use provided Windows Configuration Utility to define lanes. If lanes are not defined,
counts, occupancy and lane activation features will not operate correctly. If open drain
outputs are used, make sure they are correctly mapped to lanes. You only have to define
lanes that you are interested in, other lanes may be omitted and radar will disregard traffic
in those lanes.
Clutter map must be re-initialized after switching between highway and intersection
mode and after adjusting radar pointing, height or location.
Use Highway Mode where precise counting of the vehicles is important.
Use Intersection Mode where reliable detection of the stopped or slow moving
traffic is important
