DCP most closely replicate loop and video detectors that capture volume, occupancy, and speed. Similarly, these points also represent stationary radar guns that capture speeds on freeways or arterials. DCP can be placed on any link or connector such that the object is in a location that matches the collected field data. DCP0 record information for a single lane. To collect information for all lanes, DCP can be combined into data collection measurements (DCM). DCMs are then used to report results. Data collection points are appropriate to use when spot speed data using radar guns or other sources has been collected.
