This method has more practical value. First, this article has introduced the research situation of real-time transportation information collection, including the taxi electronic dispatch system as well as the corresponding technology. Analyzed the mothod of map coordinates transformation and the match method of vehicles localization data, then has analyzed the vehicles localization effective sampling with emphasis according to the drivers driving custom to get the tavel time of the road sections. It has filled the transportation blank region data.With the experiments of real data, explained this algorithm could obtain the road section reasonable travel time, int could describe the road network real-time condition.

本文首先介绍了实时交通信息采集的研究情况，包括电召系统以及相应的技术，分析了地图坐标转换、车辆定位数据匹配方法，然后根据驾驶员行车习惯重点分析了车辆定位有效采样对的获取并在此基础上进行单车路径旅行时间求取、时段内旅行时间求取的算法，填补了交通空白地带数据，并通过路上试验，说明该算法能够得到路段合理的旅行时间，能够描述路网的实时状态。

The system can simulate movement of vehicle, state of traffic accident and data detector. It can record every data including those immeasurable at fieldwork, which is the foundation of evaluating effect of thruway traffic accident.

在真实模拟车辆行驶状态的基础上，通过设置事故状态和数据探测器，可以全面记录车辆行驶过程中实际检测设备难以采集到的相关数据，从而为事故影响的定量分析莫定了良好的基础。

Asphalt Pavement will generate various cracks after go into service, because of the immersion of road surface water, the moisture of the pavement structure layer and the subgrade on the both sides of crack will increase, resulted in lower strength of subgrade and pavement.

随着交通量迅速增加，特别是大吨位车辆行车荷载的作用，路基、路面承受不了超载车辆荷载的作用，加快路面的裂缝产生，大大缩短沥青路面的使用寿命。本文对沥青路面裂缝常见形式和裂缝产生的原因进行了分析，同时也提出了相应的防治措施。

Model of "pavement surface-vehicle-human"vibration system is established,and the representative one-quarter automobile model with three degree of freedom is introduced to carry out dynamic analyses of the vertical vibration system.

建立&路面—车辆—人&振动系统模型，选择有代表性的三自由度四分之一车辆模型对其进行竖直方向振动系统的动力分析。

First, the color-image was preprocessed with grayscaling, smoothing. The vertical gradient components of the image were found using the vertical mask of Sobel operator. Then the candidate areas with sufficient amount of edges were determined by calculating the gradient of edges. After finding possible vehicle candidates, the proposed method measured the prominent vertical symmetry of candidate areas and verified all possible candidates, as symmetry is an important feature of vehicle. The proposed method also figured out the vertical axis of symmetry and the width of the candidate vehicle.

算法首先对图像进行灰度化、平滑去噪等预处理，使用Sobel算子垂直方向掩模计算图像感兴趣区域内的边缘梯度，确定候选区域；而后根据车辆图像垂直边缘具有对称性的特点，分析候选区域的对称性强弱，并计算其对称轴位置和车辆宽度。

Unlike the Russian BMD-3, the Chinese airborne combat vehicle cannot be airdropped with its crews in the vehicle.

不像俄国BMD-3，中国的空降战斗车辆不能够与车辆的组员一起空投。

The product can be used for armoring and defence of individual, vehicle and air craft for its lightness, high intension and rigidity.It''s important and constructive to improve defence with large market and better future.

When one of their vehicles bogs down in the mud, Henry orders the two engineers to help in the effort to free the vehicle.

当他们的车辆沼泽泥浆中，亨利命令两名工程师，以帮助在努力免费车辆。

The influence on vehicles after traffic accident happen in urban road net is analyzed in this paper. According to the degree of the accident, the capacity of the accident point is determined. The formula of travel time after accident when traffic demand upriver exceed the capacity of the accident point is given based on the dynamic law of waiting queue, which is regarded as the gist of circumambulating or not.

本文分析了城市路网发生交通事故对车辆行驶的影响，根据交通事故的严重程度不同确定事故地点的通行能力，按照排队长度动态变化的规律，给出了事故点上游交通需求大于事故点通行能力时事故路段行程时间的计算公式，以此作为是否诱导车辆绕行的依据。

The IRt/c infrared temperature sensor uses in the tire temperature to survey the vehicles the tire temperature survey to have two necessities: One, the determination temperature directly reflected the tire coheres the condition and the attrition situation; Another reason is reflects the vehicles suspension system through the temperature survey the performance.

IRt/c红外温度传感器用于轮胎温度测量车辆的轮胎温度测量有两个必要性：一是判定温度直接反映轮胎黏结状态和磨损情况；另一个原因是通过温度的测量来反映车辆悬挂系统的性能。
