• By using both the prediction model from transportation ministry and the fhwa models , the prediction results were analyzed for high ways at different sections , different design speeds , detection points , traffic volumes , distances , heights , and at various other road conditions . the prediction results and the actual results were compared and the accuracy of prediction were assessed
  本文通过比较分析了fhwa预测模式和交通部预测模式在高速公路不同监测路段、设计时速、测点、车流量、距离、高差、地面状况条件下的预测结果，并对预测结果和实测结果进行预测精度和变化趋势的比较研究。
• The 2016 estimates ranged from 85 to 164 thousand vehicles per day ( the medium assumption used in most tests was 120 thousand vehicles per day ) . almost all of the variations in volume was forecast for the two new crossings , the lingdingyang bridge ( 13 to 32 thousand vehicles per day ) and the shenzhen western corridor ( 35 to 95 thousand vehicles per day )
  到了2016年，每日的汽车流量预计会达到85 , 000至164 , 000架次（大部分测试所采用的中增长假设方案为每天12万架次） ，而预测的车流量主要是集中在两条通道上：伶仃洋大桥（ 13 , 000至32 , 000架次）及深港西部通道（每日35 , 000至95 , 000架次） 。
• The method is better than others . firstly , the system sets up several models to assist detection work , such as road model , illumination model , shadow model and relationship model among them ; secondly , it introduces hue . saturation degree information to distinguish vehicles from shadow ; thirdly , it makes use of binary decision tree to analyze pressing line of vehicles to improve the reliability of the system ; fourthly , it puts forward a way of one dimension video tracing to resolve the problem of vehicle velocity detection
  该方法通过设置在每条车道中的两条相互垂直的虚拟检测线来检测交通流信息(如车流量、车速等) ；设计一种彩色分段检测技术来提取运动车辆的尺寸信息和色彩信息，再利用分类决策树和滤波算法确定运动车辆存在与否，增强了车辆、阴影、噪声和背景之间的区分能力；设计了一种车速视频检测方法。
• And the setting standard of bus lane is also studied , which includes the standard of bus speed , the standard of bus flow rate , the standard of road condition . moreover the bus signal priority and the pre - signals are introduced and the bus priority network is planned by using the planning method of urban mass transit network . finally the methods of benefit assessment of bus lane , bus approach lane and bus transport priority network are studied , which takes the travel time of each person as standard
  系统地讨论了公交专用道、公交专用进口道、公交停靠站的设计方法和它们之间的关系；研究了公交专用道的设置标准，其中包括：车速标准、公交车流量标准和道路条件标准；对公交优先信号、公交预先信号进行了介绍；应用轨道交通线网规划的方法对公交优先通行网络进行规划；以人均出行时耗为指标对公交专用道、公交专用进口道、公交优先通行网络的效益评价方法进行了研究，并且建立了数学模型。
• In our country , most of bridges were built in 1960s or 1970s , which were based on that time traffic discharge and development planning , so design criterion of these bridges were very lower . in addition , it was inevitable to bring about cracks > concrete rupture , steel rust ^ honeycomb and water proof layer failure , because some established bridges were built by poor construction and maintenance during the course of operating period . all above mentioned lead to durability and bearing capacity could n ' t gain to design standard
  由于我国很多桥梁建于上个世纪六、七十年代，基于当时的车流量和各方面的发展规划，桥梁设计等级普遍偏低；另外，某些既有桥梁由于施工质量差和运营期间维护不到位，不可避免地会产生裂缝、混凝土破损、钢筋锈蚀、蜂窝及防水层失效等缺陷，从而导致耐久性及承载力达不到设计要求。
