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） 。
In principle , ultrasonic sensors are suspended over a road , which keep emitting pulse signals periodically to nearby and feed back waves to decide existence of any obstacles , thus to detect the speed , height , length , different sizes ( heavy , medium and small ) of moving vehicles and accumulative flow as well as length of motorcade . optionally , it can be applied to multitude driving lanes simultaneously for traffic data . by integrating and analyzing these measured data , the necessary figures concerning traffic flow may be obtained , which are fundamental basis guiding road buildings 本课题设计的是一种悬挂式超声波车流多信息检测器，通过悬挂于路面上方的超声波探头向路面周期性地发射脉冲信号，利用地面回波来判断遮挡物地存在，可用于检测行驶中的机动车车速、车高、车长、大中小分型以及累计车流量、车队长度等信息，并可用于多个车道车流信息的同时检测，综合这些测量参数可获得车流量的必要数据，可为公路建设提供必要的基础依据。
Abstract : based on the condition of sustainble development practice in china , further explorations of the big city transportation development are made , of which include controlling the main city zone size , combining new area construction with old town environment improvement , developing new commercial central mall , planning and constructing metro reasonably , restraining central area vehicle volume at peak hour by some proper measures and enforcing public parking space constructing and management 文摘:从可持续发展概念及我国国情实际出发，对我国大城市交通跨世纪发展战略进行了探讨.从六个方面提出了建议：它包括疏解用地布局控制主城区发展规模；加强新区建设与重点改善旧城环境相结合；辟建新型商业步行街(区) ；从城市规模实际出发，合理规划建设地铁；采取措施抑制中心城区高峰车流量及加强城市社会公用停车场布局建设及经营管理
