微处理器技术的最新进展使得对高速公路交通视频图像进行经济有效的计算机处理以测量交通速度、流量和密度成为可能。视频图像处理系统 (VIPS) 现在被视为高级交通管理系统 (ATMS) 的关键组件。应加州交通部的要求，最近对八个商用或原型 VIPS 的有效性进行了评估。测试程序旨在复制加州高速公路系统中常见的情况。报告测试结果的摘要。大多数系统在最佳条件下表现良好，但在非最佳条件下性能显着下降，具体情况因系统而异。根据所研究的 VIPS 系统，该技术被认为对于特定的交通监控问题是可行的。确定了限制和进一步发展的领域。
Recent advances in microprocessor technology have made possible the cost-effective computer processing of video images of highway traffic for measurement of traffic speed, volume, and density. Video image processing systems (VIPS) are now being considered as key components of advanced traffic management systems (ATMS). Eight commercially available or prototype VIPS were recently evaluated for effectiveness at the request of the California Department of Transportation. Test procedures were intended to duplicate conditions typically encountered on California freeway systems. A summary of the test results is reported. Most systems performed well under optimum conditions but degraded significantly under nonoptimum conditions, which varied from system to system. On the basis of the VIPS systems studied, this technology is considered feasible for specific traffic monitoring problems. Limitations and areas for further development are identified.
