不同光照条件下直线型车道标识识别方法研究

为了解决不同光照条件下车道标识的识别，提出一种基于双标准可调模板关联技术的车道标识识别方法。该方法首先根据光照的变化采用不同的预处理技术对图像进行处理，然后利用基于统计的方法得到车道的初始化标识线，最后在以该书初始化标识线为尽准建立的感兴趣区域内利用双标准可调模板关联技术对初始化标识线进行矫正从而得到可靠的车道标识线参数。     

盾构隧道穿越既有建筑物施工应对技术

随着近几年地下工程建设的不断发展,盾构施工技术已越来越成熟,特别是在城市轨道交通建设中更显示出其优越性。但是,对于盾构施工过程中穿越障碍物或近距离通过既有建(构)筑物的施工还缺少相应的工程实例,经验相对也较少。近年来,我国城市轨道交通建设发展迅速,但是面临着越来越复杂的周边环境和施工条件,因此研究和制定相应的施工技术和应对措施十分必要。文章针对盾构施工穿越城市内河、下穿既有隧道以及湖底施工、下穿古城墙等工程实例进行分析研究,提出了针对类似情况的应对技术措施。     

Reliable route guidance: A case study from Chicago

Reliable route guidance can be obtained by solving the reliable a priori shortest path problem, which finds paths that maximize the probability of arriving on time. The goal of this paper is to demonstrate the benefits and applicability of such route guidance using a case study. An adaptive discretization scheme is first proposed to improve the efficiency in computing convolution, a time-consuming step used in the reliable routing algorithm to obtain path travel time distributions. Methods to construct link travel time distributions from real data in the case study are then discussed. Particularly, the travel time distributions on arterial streets are estimated from linear regression models calibrated from expressway data. Numerical experiments demonstrate that optimal paths are substantially affected by the reliability requirement in rush hours, and that reliable route guidance could generate up to 5-15% of travel time savings. The study also verifies that existing algorithms can solve large-scale problems within a reasonable amount of time.

Rail and multi-modal transport

This paper elaborates on the definitions of inter and multi-modal transport, as well as their differences in terms of performance. A survey of the barriers, both internal and external, to an efficient intermodal transport is included followed by an analysis of the advantages and disadvantages of combining rail transport with the other transport modes. Transhipment technologies for efficient freight service and some examples of freight rail corridors between sea and inland terminals are presented. The integration between air and rail transport is discussed and the potential synergies between air and high-speed rail services are emphasised. The paper concludes with a discussion on energy use for sustainable rail performance.
