3. No 'bottleneck congestion' dredging strategy is provided for congested road sections;
the congestion phenomenon can appear at the main crossing in the central city area during the peak period of morning and evening, the queuing length can extend to the next crossing when the congestion phenomenon is serious, but the current signal equipment does not support the function of congestion control, the traffic can not be dredged through the change of reasonable signal period, the traffic can only be directed by the police to the crossing, and the efficiency is low.
4. The inability to implement demand control for a particular area;
during holidays, traffic demands in busy areas of a city are excessively concentrated, vehicles in the busy areas are excessively saturated, and a ' dead-up ' state that the vehicles cannot walk ' is caused.

The software environment is as follows:
windows Server 2003/2008 series versions.
The monitoring map is used for monitoring the upper and lower line states of the signal lamps in real time, the signal lamps display the colors of the signal lamps on line, and the signal lamps display gray when off-line. The user can view the real-time condition of the intersection by clicking the signal machine on the map.
The equipment information management is to store and manage information such as the number, name and installation intersection of the signal equipment, and is convenient for a manager to check and manage.
The green wave band is that when executing tasks such as guard, fire control, rescue, emergency rescue, etc., each traffic signal lamp on the driving route turns on the green lamp according to the time when the vehicle arrives at the intersection, thus ensuring the vehicle to be smooth without obstruction. The annunciator system can manage the green wave band line, the administrator can manually turn on or turn off the privilege of the green wave band, and the system synchronously sends the information to the controller, thereby realizing the control of the green wave band.
The signal machine supports guard route control, and when an emergency occurs or important vehicles need to pass through, special lines can be arranged for the vehicles to pass through quickly, so that the quick passing of fire-fighting vehicles and rescue vehicles is guaranteed.
The flow statistics is to count the traffic flow of the lane in a period of time, including parameters such as traffic flow, average vehicle length, equivalent cars, average headway distance, average headway time, average speed, saturation, density, average queuing length and occupancy, and to process the parameters to generate a line graph, and to visually display the variation trend of the line graph to a manager. And the management personnel can conveniently record and schedule. In counting, firstly 'intersection selection' is needed, then 'lane selection' is needed, and finally 'start time' and 'end time' are selected.
The intersection control comprises modules of time period setting, phase setting, timing setting, special day setting, strategy setting, green conflict setting and pedestrian button setting. The time interval setting is to set the operation scheme and the control type of the signal machine in different time intervals, and comprises the following steps: 14 control types such as special control-turning off the lamp, special control-full red, special control-full yellow flashing, single-point multi-period timing control, single-point induction control, single-point self-adaptive control, line coordination control, area coordination control and the like; setting phase information, supporting 32 sets of phase schemes, wherein each set of scheme can set 64 phases; the timing setting is to set the green light time, the green flash time, the yellow light time, the red light time, the minimum green time and the maximum green time in the phase scheme; the special day setting aims at the conditions that the vehicle traffic at some intersections increases or decreases in the legal holidays and weekends and the like, intersection control needs to be adjusted, and the reasonable control on the intersection traffic order is completed; the operation strategy setting of the gateway control machine is completed by sending the strategy setting of the annunciator system to the control machine; the green conflict setting specifically comprises: the signal lamp controller controls the green signal lamp to release people flow or vehicle flow in the corresponding direction of the urban road condition, if two conflicting directions are released simultaneously, serious threat can be brought to the traffic safety of the road junction, and traffic accidents are easily caused. Therefore, the green lights in the conflicting directions must not be simultaneously lit. If the green signal lamps with the conflicting directions are simultaneously lighted, the green signal lamp conflicting faults are called as signal lamp green conflicting faults. In order to avoid green conflicts, conflict lamp sets can be manually set; aiming at the condition that pedestrians are few at the intersection, the pedestrian button is additionally arranged, so that the automobile passing rate can be effectively improved, and the pedestrian button can be used for setting the time length of motor vehicles of red and green lights at the intersection, the time length of pedestrians, the triggering time, the extension time and the like.
The equipment parameter configuration comprises common setting, equipment serial port setting, equipment countdown setting and equipment lamp group setting. The common setting is to set basic information of the controller, including setting management such as equipment attribute, serial port address, network address and automatic maintenance. The device serial port setting is to set the basic information and the working mode of the serial port. The device countdown setting is to set a countdown parameter; the equipment lamp group is used for setting lamp group information and supporting 8 driving plates, each driving plate corresponds to one intersection direction, each driving plate is provided with 6 lamp groups, and 48 lamp groups are arranged in total.
During the operation of the signal, some problems which are difficult to avoid may occur, such as: lamp bank output failure, power failure, green conflict failure, drive plate failure and the like, and maintenance personnel are required to perform maintenance work at this time. Timely and accurate problem feedback is helpful for carrying out maintenance work smoothly as soon as possible, and loss caused by the maintenance work can be reduced. The short message configuration function can perform rule configuration on different problems aiming at the problems and send the problems to management personnel or maintenance personnel in time.
The user management is a management of information of a user (user) of the traffic signal system, and is divided into two parts, user information management and user password management. The user information management is to input and delete basic information of a user, including name, number, contact telephone and the like. The user password management can modify the password of the user, the administrator can modify the passwords of the user and other common users, and the common users can only modify the passwords of the user.
The system setting is to manage the use role and the use resource of the system, and comprises the authorization of the role and the authorization of the resource. The role management can add, delete and change the used roles of the system. The user authorization management sets the authority of the system user, and the authority level comprises an administrator, an operator and a common user (visitor). The resource management is used for adding external resources in an extensible manner for the annunciator system. The resource authorization management is to set the access authority of the system role, select the system role, and then check the resource allowed to be accessed to complete the role authority setting.
A single-point control interface user for signal monitoring can check information such as a phase, phase remaining time, an operation mode, a control type and the like which are currently operated; the time-adjusting interface user can adjust each phase time in the current operation scheme, which is divided into 'temporary time adjustment' and 'scheme time adjustment', after the time adjustment is completed, after the click is successfully issued, when the phase time of the next period walks according to the current adjusted time, the time is operated according to the current updated time unless the annunciator is closed, and after the scheme time adjustment is successfully issued, the phase time is updated even if the annunciator is restarted, and the time walks according to the modified time; the phase-locked control interface is on the real-time operation interface, and can also perform phase-locked control, through the phase-locked control, a user can remotely lock the annunciator in a certain signal lighting state, and the locking state comprises a temporary locking state and a permanent locking state; and (4) permanent locking, namely, even if the signal machine is restarted, the server software does not send an unlocking instruction, and the signal machine can still be locked for a long time. Another state is temporary locking, which is sometimes limited by a long time, and the semaphore is temporarily locked in one or several phases. And when the timing time is up, the annunciator automatically unlocks and runs to the state before unlocking. The streaming control user can quickly lock all signal lights permanently or temporarily to off, yellow flashing, or full red states. The scheme control user can select the current phase operation scheme and also can modify the existing scheme; the device adds an semaphore on the map, and the process of adding needs input semaphore serial number, and is best all to set ID, the IP of semaphore the same, convenient management like this, and when adding the semaphore, the street name that this semaphore belongs to is generally input to the device name, and the IP is the network segment that the server belongs to. And simultaneously adding a big team and a middle team to which the annunciator belongs.
And a special service task setting step, wherein a user can check the currently configured special service route by clicking a special service task button, and if no special service task route exists currently, the user can add a special service task. The special service route adding method includes that a special service route is named firstly, a user can name according to actual use or name according to a route, and then a special service task ID number is added. And clicking the annunciator on the map when the annunciator executing the special duty task is added to add the annunciator into the route of the current special duty task, and clicking and storing after the addition is finished. And (4) enforcing control, and enabling the special service line added by the user. And clicking 'forced control', entering a control prompt interface, clicking to determine, entering a special duty control mode, and selecting the operation phase, the locking mode and the like of the annunciator by the user according to the actual application condition. After the setting is finished, starting can be selected and forced to take over, and the special duty task route is effective at the moment. The special service information can be checked by clicking 'information' in the special service task by the user, and the special service information can be modified through the interface while the user checks the special service information. After clicking on "modify," the special service modification interface is activated. The user can modify information such as lines through the interface.
In the equipment configuration step, the most interaction between the management platform and the annunciator is the configuration of the characteristic parameters, which is the most important ring related to the platform to control the annunciator. The most commonly used configuration of the characteristic parameters are four parameters, namely, lamp group configuration, scheme configuration, timing configuration and time base configuration. The light bank configuration may enable all driver boards and light banks. The general type of the lamp group can be set according to the purpose of the lamp group, and the conventional motor car has main lamps, left-turning, straight-going, right-turning, pedestrian movement and the like. After the lamp group is set, the scheme configuration is started, a user configures the phase according to the actual use condition, and simultaneously assigns the lamp group to the phase, so that the user can configure a plurality of operation schemes at the same time for selection. The time sequence configuration comprises total time sequence configuration, timing time sequence configuration and optimized time sequence configuration. Wherein the overall timing configuration comprises an optimized timing configuration. In the process of configuring the time sequence actually, the user should configure the timing time sequence and the optimized time sequence first, and then configure the total time sequence. The general signal machine mainly uses timing sequence except induction control. When configuring the timing sequence, the user can configure the time interval according to the actual requirement and appoint the operation scheme of the time interval at the same time. If there are multiple running time sequences, multiple timing time sequences can be configured; the optimized timing is similar in configuration to the timing. When the optimal matching is carried out, control modes such as full-induction control, semi-induction control, flow self-adaption, queuing length self-adaption, pedestrian request, bus priority and the like are adopted. If the optimized time sequence has a plurality of time intervals, a plurality of optimized time sequences are set, so that management and control are facilitated; after both the timing sequence and the optimized timing sequence are configured, the total timing sequence can be set. The setting of the total time sequence is based on the actual application of the user, and the timing time period is determined according to the timing time sequence and the time period of the optimized time sequence; the time base configuration is mainly used for configuring the running time sequence of every day from Monday to weekend and the running time sequence of special date, and the time base is not required to be replaced after being generally configured; and after all time sequences, schemes and time bases are configured, uploading the configured parameters to a server, and downloading the configured parameters to the designated annunciator, thereby completing the parameter setting of the annunciator.
The abnormal state monitoring part related to the method comprises line aging detection, and the system feeds back the detected line aging problem in time, so that the output power, the current and the voltage can be tested. At present, common traffic light lines are pre-buried in pipelines below the ground for a long time, and the lines are aged due to long-term water soaking, so that the situations of electric leakage, short circuit, line burning and the like are caused, and the life safety of citizens is seriously threatened. After the method detects the aging and electric leakage degree of the line, related maintenance personnel can be informed to replace the line in time.
The remote control of the method can realize the function of remote power-off; when the road junction finds electric leakage and affects the life safety, the power supply can be remotely turned off. Meanwhile, remote control can also realize functions of mobile phone query, fault mobile phone short message prompt, mobile phone alarm prompt, fault timely query, remote parameter modification and the like.
The road traffic related data in the area collected in the self-adaptive function of the method comprises audio, video and other data.
