Traffic simulation models offer significant benefits, but after 35 years of development and application, they still have shortcomings. A new study seeks to fill in the gaps.
"The objective of NGSIM is to develop behavioral algorithms in support of microscopic traffic simulation, with supporting documentation and validation data sets. All NGSIM products will be freely available to simulation model developers and the transportation community at large.
...Vehicle detection is accomplished by extracting line segments from images and matching them to 3-D vehicle models. "This algorithm shows superior vehicle localization performance in varying illumination conditions compared to the previous motion-based approaches," he added.
Once a vehicle is detected, it can be tracked based on its appearance in the camera image. A sequence of cameras is used to track the detected vehicles along a stretch of freeway. Vehicles in the overlapping area between two cameras are passed from one camera to the next by comparing their appearance in both cameras."
