智能运输系统(Intelligent Transportation System,简称ITS)的设想并非今日才有。ITS的产生起源于汽车和公路交通运输的发展。目前各国和各方面专家对智能运输系统的理解不尽完全相同,但比较公认的含义是:ITS是将先进的信息技术、数据通讯传输技术、电子控制技术及计算机处理技术等综合运用于整个交通运输管理体系,建立起一种实时、准确、高效的综合运输管理体系,最终使交通运输服务和管理智能化。 相似文献

ABSTRACTInformation accuracy and decision-making speed are of paramount importance in managing today’s mobility of goods and people inside the city. Intelligent Transport Systems (ITS) can provide road users with updated information and forecasts on both traffic and weather conditions. The result is a higher efficiency in the use of resources and a better management of physical flows. The purpose of this paper is to conduct an in-depth review on the role of ITS supporting urban Smart Mobility, in order to identify the main gaps in the literature and propose future research streams. In total, 71 papers have been thoroughly analysed: they are mainly focused on technology, with limited attention to value creation. Even though some benefits have been examined, a general lack of quantitative models emerged. Eventually, there is a lack of contributions considering both people and freight transport, even if they are strongly related, especially in an urban environment. 相似文献

Histogram time series (HTS) and interval time series (ITS) are examples of symbolic data sets. Though there have been methodological developments in a cross-sectional environment, they have been scarce in a time series setting. Arroyo, González-Rivera, and Maté (2011) analyze various forecasting methods for HTS and ITS, adapting smoothing filters and nonparametric algorithms such as the k-NN. Though these methods are very flexible, they may not be the true underlying data generating process (DGP). We present the first step in the search for a DGP by focusing on the autocorrelation functions (ACFs) of HTS and ITS. We analyze the ACF of the daily histogram of 5-minute intradaily returns to the S&P500 index in 2007 and 2008. There are clusters of high/low activity that generate a strong, positive, and persistent autocorrelation, pointing towards some autoregressive process for HTS. Though smoothing and k-NN may not be the true DGPs, we find that they are very good approximations because they are able to capture almost all of the original autocorrelation. However, there seems to be some structure left in the data that will require new modelling techniques. As a byproduct, we also analyze the [90,100%] quantile interval. By using all of the information contained in the histogram, we find that there are advantages in the estimation and prediction of a specific interval. 相似文献

文章介绍了基于视频的车辆测速管理系统,并提出了一种车辆的测速方法。车辆测速管理是智能交通系统(ITS)中的一个重要组成部分,它集牌照识别、测速检测、流量监控、费用收取等多项功能于一体,主要用于对高速公路超速违章车辆的监控。在车辆的测速原理中,指出从相邻视频帧图像中获取车辆的"像速度",并间接获取车辆实际速度的方法。从而为高速公路测速管理系统的关键点提出了一种切实可行的解决办法。 相似文献
