1、Part One - Answer the questions in simple way (简答题) (每题3分)1.What is tCourse series No. 000211 Grade No. 0304612006年度“交通工程总论”试题(A卷)姓名 学号 分数Part One - Answer the questions in simple way (简答题) (每题3分)1.What is the objective of traffic engineering study (交通工程研究的目的是什麽)答:交通工程研究的主要目的是保证交通安全,以及实现快速、舒适、方便、经济及
2、与环境相协调的客货运输。2.What is the difference between rate of flow and hourly volume (小时流率与小时流量有何区别)答:小时流量是指一小时内通过观测断面的实际交通量。小时流率通常是将某连续时间段(小于一小时)内的交通量扩大为一小时得到的交通量。小时流率是放大的相对小时流量,小时流率一般大于小时流量。3.What are the definition of 85th percentile speed and its meaning in traffic engineering (百分之八十五位车速的定义和在交通工程中的含义是什麽)
3、答:在一路段行驶的所有车辆中,有85%的车辆行驶速度在此速度之下,只有15%的车辆行驶速度高于此值,交通管理部门常以此速度作为某些路段的最高限制车速。4.What are the leading and lagging phases (何谓先行和后滞相位)答:先行相位是指当一方向车辆获得绿灯时,其对向仍禁止通行的相位分配方式。后滞相位是对正在运行的对象双方一方先禁止通行,而另一方继续给与绿灯的相位分配方式。5.What is the effective green time (何谓有效绿灯时间)答:实际绿灯时间、黄灯时间中,除掉损失时间后,实际上用于通车的时间即为有效绿灯时间。6.What i
4、s follow-up time (何谓随车时距)答:次要道路上,前后两车保持的保证两辆或两辆以上车辆安全穿越主干道的最小平均车头时距。7.What is critical lane (何谓关键车道)8.What is saturation flow rate (何谓饱和流量)答:饱和流量是在车辆处于饱和车头时距的条件下,一小时通过的交通量。1Course series No. 000211 Grade No. 0304619.Under what conditions is time mean speed equal to space mean speed (时间平均车速与空间平均车速在什麽
5、情况下相等)答:根据公式2211111inniiiiidtTMSntntnndSMSntntt=´´³´×´×åååÕÕå等号成立条件为ti=tj ( ij )即道路上所有车辆的地点车速均相等的情况下,时间平均车速等于空间平均车速。¹10.Using diagram to show weaving areas of freeway. (用图表示高速路交织区)Crown lineL (<2500 ft.)交织区示意图Part Two - Elabora
6、te the following questions (详述下列问题) (每题6分)1.Describe the relationship between mobility and accessibility. Then, take Jing Jin freeway and Da Wang roadway as candidates to show their difference in terms of mobility and accessibility (描述机动性与可达性之间的关系, 并以京,津高速路和大望路为例加以说明)答:机动性和可达性是出行的两个因素。机动性注重的是出行过程的效率
7、;可达性注重出行过程的方便程度。随着机动性的增加,可达性程度降低。如京津高速,由于全封闭、全立交对车辆行驶的干扰小机动性较之其他道路高,但通过它能够直接到达目的地的能力下降了。而大望路道路两侧干扰严重车辆运行效率低,但可达性好。2.Illustrate the difference between the two way stop and full way stop. (试说明二路停车和全路停车之间的区别)答:二路停车指一种用于主,次路相交的无信号交叉口的控制方式,次干道进口安装停车标2Course series No. 000211 Grade No. 030461志牌,主干道车流不受到限制
8、通过路口,次干道车流必须让位给主干道车流,利用主干道车流中的可接受间隙通过路口;全路停车则指等级相同道路相交的无信号交叉口的控制方式,交叉口各进口均安装停车标志牌,所有进入交叉口的车辆必须停下来按照先到先行原则通过路口3.Illustrate the basic principles used for signalization of intersections in MUTCD. (叙述MUTCD中有关在交叉口采用信号灯的基本原则)答:1. 交通流量原则;2. 行人与自行车原则;3. 学校穿行原则;4. 信号协调原则;5. 冲突原则;6. 路网原则。4.Describe the relati
9、onship between number of phases and the delay drivers experience at signalized intersection. (描述信号相位数与交叉口延误之间的关系)答:随着信号相位数的增加,交叉口一个进口方向上总延误时间增长。List all factors affecting free-flow speed of freeways. (列出影响高速路自由流速度的因素)答:影响多车道公路自由流速度的因素主要有:车道宽度,路侧净空,车道数及立交密度。Part Three - Calculations (计算题)1.Given the
