With the development of the modern technology,private car is no longer a luxurious thing for ordinary people,more and more people drive to work instead of going by The popularization of private car has many First, it is very convenient and time-saving ,you can drive your own car to the workplace instead of waiting for the crowded bus and afraid of being late for Second,it can also improve the traffic structure,and help to mitigate the stress of the Third, the popularization of private car can help to promote the car industry and any other interrelated I believe that in the future the private car will become the most important vehicle and we cann't live without More and more people makes the traffic busier and Most people keen to live in the big cities where are more convenient and the children can receive better But the problem is the heavy traffic create too much pollution which does great harm to human's So, to keep ourselves safe, I think we should do some We should obey the traffic rules whenever we are and even when we are in a deadly When we are walking, we should walk on the At the crossing, we shouldn't cross the road until the traffic Don't play basketball, read books or listen to music while In a word,we must be With the development of industry and economy, more people from rural area are pouring into big cities and more vehicles are going on to the As a result, many cities are faced with the serious problem of traffic congestion, which has become one of the major concerns of the   To solve this problem, many people have put forward many solutions, of which the following two are the most One is to lay down more roads, which will make the highways less crowded and accelerate the flowof Another is to open up more bus routes, which will enable more people to take buses rather than ride bikes or drive cars, thus decreasing the number of cars and bikes racing on the   However, both of the suggestions have The former may occupy too much land, which may be otherwise put to better The latter, on the other hand, will bring inconvenience to those who are living far away from the bus The best solution, in my opinion, seems to be the combination of the two: toay down more roads in spacious areas and to open up more bus routes in downtown

General control of cross-ring 1 passage space design Import Road Layout The purpose of the implementation of signal control is to enable different traffic flows, the separation in In order to facilitate the implementation of signal control, it is necessary to import Road lane divided function (see Figure 4), enables the flow of traffic各行其道to avoid mutual Central Road layout Different flows in order to avoid causing traffic chaos intertwined, Central Road improve traffic capacity, as well as with the import function to match the Road driveway, it is necessary to Ring Road also divided roadway function, is mainly divided into lanes to turn left and go straight ahead (see Figure 4) Ring Road that is at least has a straight, a left turn 2 Determination of signal phase Because of the role of Bay Road, the traffic to turn left and straight on to the conflict between traffic can actually evolve into a degree of interwoven, the result of the implementation of four-way ring to pay the general control, to be used in the form of two-phase control; more Road Central, submitted by the specific circumstances of the case to determine 3 signal configuration and priority rules Signal configuration based on the above analysis, the arrow lights should be configured in order to facilitate the flow of different traffic with different traffic Priority rule ring along with the phase because of the existence of different traffic flows, the left turn traffic flow and traffic flow straight to the potential for conflict exists between, it was necessary to set the priority rules, usually in the same phase, the straight traffic stream have precedence in the left turn traffic flow (also visible on the actual situation) 4 Signal Timing Ring Road divided roadway function and implementation of signal control can be used to eliminate cross-Ring Road in the loop-cutting issues, thus the control method in the signal control principle with the general level-crossing control method is similar to Webster-based allocation method to determine when the timing program, and depending on the actual coordinate the flow of traffic than the actual green However, due to the Central Road, vehicles traveling the speed limit and driving distance is longer, according to the practice of using yellow light time of 3s may lead to the end of yellow line to turn left through the parking of vehicles with another phase of the early exit of vehicles (cars to turn left or go straight vehicles) in the Bay Road entrance of intertwined or conflicts, which have a need to re-determine the time between green and yellow light Located around the island radius r0, Ring Road, the width of each lane w, calculated traveling speed v0, the driver reaction time t0, then import Road vehicles from passing through the most lateral straight junctions adjacent most lateral point of conflict is about the shortest distance (17) So (two-phase case) the Green interval I for (18) By type (13) yellow light time can be 5 Ways to control the application of the conditions of analysis Flow conditions are usually, non-signal-controlled roundabout capacity value of the experience of 2 000pcu / h or so, so when the actual traffic demand roundabout approach or exceed the value of this experience that it is necessary to the implementation of signal control is proposed in this paper The three kinds of control mode, both for flows exceeded 2 000pcu / h and the control signals required to pay in terms of The first two kinds of control method is more applicable to a larger left turn traffic Intersection turn left two-step control of the geometric conditions of the ring to pay, generally applicable to large diameter around the island, Central Road has enough space for traffic to turn left holding queue of traffic flow; turn left step in the control (not around the island) of the Central settlement, generally applies to smaller diameter around the island, around the island has enough space for laying the traffic lane to turn left into the traffic flow of space, and turn left trochoid truck lanes turning radius should be not less than diversion routes set up in accordance with the minimum requirements turning radius; the implementation of the general control of the ring to pay, the general can not satisfy the above two control methods of the geometric conditions (also unable to broaden the reach of these requirements)

General control loop 3 For ease of implementation of signal control, it is necessary to import into tao driveway function (see chart 4), make the flow of traffic flow separately, avoid mutual 2 ring road layout In order to avoid the traffic flow caused by different interweave, improve ring road traffic chaos ability, as well as with imported word matching driveway, necessary function will ring road is divided into the driveway turn function, main is to go (see figure 4 special 2 phase signal Much of vessel into the visual 3 lights and priority rule 1 signal based on the above analysis, configuration, configuration of different arrow signal of traffic flow to different traffic 2 because of priority rule ring road phase with different flow of traffic, the traffic flow to the left and went toward the conflict between traffic flow, therefore, it is necessary that may set priority rule, usually in the same phase, straight traffic flow precedence left traffic flow situation (visual) 4 signal timing Ring road into the driveway and signal control implementation, can eliminate ring road in the ring, and control methods in signal control principle with general adjustment and control method can be delivered in accordance with similar Webster timing method, and the timing scheme based on actual traffic flow of coordinate than actual green But because ring road vehicles driving speed limit and long distance, as usual used 3s yellow light yellow lights time may lead to the left end through this vehicle with another aspect of the vehicle (left early exit the car or direct driving) in the entry word ring, or conflict and necessary to determine with yellow lights inter-green time R0 radius, set huandao road every lane width w, computing speed limit, the pilot v0 t0 reaction time, the lateral straight vehicles imported way across most of the adjacent intersections ChongTuDian about the most short (17) Then (two phase) green interval for I (18) By type (13) can determine the yellow 5 the control method of the applicable condition analysis 1 traffic conditions, no signal control usually annular intersections experience for 2 000pcu ability, so when the h/hen th actual traffic demand or exceed the experience, it is necessary to implement the signal control, this paper puts forward three kinds of control mode for more than 2, flow 000pcu/h and signal control loop The former two more applicable to control the flow of Turn 2 intersection of two steps geometric conditions of control loop turn into, generally applicable huandao road larger diameter, ring has enough space for traffic stopped traffic flow line left waiting, Don't turn around the island controls (step) into the ring, applies to smaller diameter, huandao around the island has enough space layout of the traffic flow of traffic space left, and left the car driving line should not be less than turning radius, in accordance with the requirements set diversion road for minimum turning radius, Implementation of the ring, general control into two general cannot satisfy the requirement of geometry control method can broaden reach above (required) The annular intersection control, mostly to implement signal intersection control method, thus effectively adapt to the characteristics and annular intersection traffic reasonably to solve the traffic problem is hen Study limitations, because all three modes of motor vehicles and pedestrians not study of interference and some other possible circumstances, therefore remains to be combined with actual situation for further improvement 我是用有道桌面词典来翻译的,如果你需要,可以从这里下。
