Applying the correlation analysis method,the author presents a brief and valid algorithm to i-dentify the pulse response function of a road section,which uses the natural stochastic signals in measureddata of traffic volume on the section. Based on the pulse response function,a new algorithm to estimate themean speed Of vehicles in the section during a long time interval for light traffic conditions is also presented. Moreover,an algorithm to identify the mean effective vehicles length is put forward. The merits of these al-gorithms are that they do not need to measure the speed of each vehicle and the double-loop detector shouldnot be required.

Automatic incident detection algorithm is the core of ATM. Now, most of the incident detection algorithms adopt speed, occupancy and/or volume as detection parameter obtained from loop detector. But these algorithms need a number of loop detectors with certain distance. At present, in China there aren't enough loop detectors on the freeways. So the detection effect is limited in practice. As for Chinese freeway is concerned, the authors attempt to develop a new freeway incident detection algorithm...

Automatic incident detection algorithm is the core of ATM. Now, most of the incident detection algorithms adopt speed, occupancy and/or volume as detection parameter obtained from loop detector. But these algorithms need a number of loop detectors with certain distance. At present, in China there aren't enough loop detectors on the freeways. So the detection effect is limited in practice. As for Chinese freeway is concerned, the authors attempt to develop a new freeway incident detection algorithm based on data fusion. The algorithm combines the traffic information of mainline with the information of tolling station to detect the incident. Finally, as the simulation results shown, the new algorithm for incident detection has a lower false alarm rate and a higher detection rate, and it can improve the detection. The algorithm would have a bright prospect in China.

高速公路事件自动检测算法是高速公路事件管理系统的核心。目前的事件自动检测算法普遍采用流量、速度和/或占有率作为检测参数,这些参数可由道路主线上的检测器得到。但这种检测方法要求路上埋设有一定密度的检测器。而目前在我国的很多高速公路上都存在着埋设检测器数量少、间距大的现象,以至这些算法在实际应用中检测效果很不理想。针对高速公路检测器的埋设现状,提出了一种新的事件检测算法,将主线检测器得到的信息和收费口处得到的信息进行融合来判断交通事件的发生。仿真试验表明:与传统事件检测算法相比,该算法具有更高的检测率、更低的误报率,可以明显改善检测效果。

The accurate,real-time traffic speed data are important for a successful freeway traffic management system.Unfortunately,vehicle speeds cannot be directly measured by single-loop detectors.In this paper,a simple model method of single-loop data based for speed estimation is presented,different models are used to estimate speed according to different traffic conditions such as free flow and congested flow.Speeds estimated by this method are very close to the speeds observed by the corresponding dual-loop detector.Compared to the commonly adopted speed estimation algorithm,the proposed method improves estimation accuracy significantly.

实时准确的交通速度对于成功的快速路管理系统来说是至关重要的。然而,交通速度并不能直接从单线圈检测器测量出来。论文提出了一种基于单线圈输出量进行速度估计的简单模型方法。该方法考虑自由流和拥挤状态下分别采用不同的模型进行速度估计。利用该方法估计出来的速度非常接近于双线圈测量的速度观测值。与以往的算法相比,该方法简单实用并且明显地改善了速度估计。
