Improved Velocity Estimation Using Single Loop Detectors

This paper develops an improved algorithm for estimating velocity from single loop detector data. Unlike preceding works, the algorithm is simple enough that it can be implemented using existing controller hardware. The discussion shows how the benefits of this work extend to automated tests of detector data quality at dual loop speed traps. Finally, this paper refutes an earlier study that fou...

1 Loop Detectors : Results ofControlled Field Studies

I nductance loops play a major role in vehicle detection systems that provide data for use in traffic-actuated signal control and other surveillance systems. Considering the wide variety of vehicles on the road today, it has become increasingly important to find a loop configuration that can accurately detect oddsized vehicles. Odd-sized vehicles include motorcycles, mopeds, bicycles, and high-...

Remote Automatic Incident Detection Using Inductive Loop Detectors

This paper describes the RAID algorithm, (Remote Automatic Incident Detection) designed to detect abnormal periods of traffic congestion existing over single inductive loop detectors (typically 2m by 1.5m). RAID identifies those detectors which show a critical increase in Average Loop-Occupancy Time Per Vehicle (ALOTPV) coinciding with a critical decrease in Average Time-Gap Between Vehicles (A...

Estimating Travel Times and Vehicle Trajectories on Freeways Using Dual Loop Detectors

Recent research has investigated various means of measuring link travel times on freeways. This search has been motivated in part by the fact that travel time is considered to be more informative to users than local velocity measurements at a detector station. But direct travel time measurement requires the correlation of vehicle observations at multiple locations, which in turn requires new co...
