Comprehensive evaluation of the location of traffic safety signs Lv Yunxiang (Road Management Section of Nanjing Management Office of Ninghuai Expressway in Jiangsu Province) reform and construction of various undertakings in the region. In the new era, the state advocates the implementation of macro-control of traffic engineering. The transmission of traffic information is the basic requirement for maintaining traffic flow and road safety. It is a practical way to use flexible signs to complete traffic information transmission. As a traditional marking method, safety signs play an important role in the safety construction of traffic engineering. It analyzes the related problems of the location and control of traffic safety signs, aiming to create a safe and feasible driving environment.

1 The current status of traffic safety in China. Reviewing the development of China's transportation industry, accidents have always been a direct factor restricting the development of transportation. The consequences of safety accidents are unimaginable. The investigation found that the frequent occurrence of traffic accidents was related to drivers' drunk driving, bad weather and natural disasters. Many accidents were also caused by the untimely delivery of traffic information. For example, when a driver encounters a strange road, he does not have a safety card as a guiding tool for the local road section. The driver's driving direction is inaccurate and collision, rear-end collision, etc., and the serious traffic accident is a major traffic accident. The entire traffic line is subject to Obstruction.

The current situation of traffic jams. According to the 2011 Global Industry Report, the world's total number of cars exceeded 1 billion, and China ranked second with a total number of 78 million. In addition to frequent safety incidents, road traffic jams are also a common phenomenon in China's traffic, and urban traffic congestion is even more difficult to solve. Social surveys have found that traffic jams in first-tier cities in China are particularly serious. First-tier cities such as Beijing, Shanghai, Guangzhou, and Shenzhen are traffic jams throughout the year. Commuting and commuting, traveling, etc. are the peak periods of traffic jams. More than 70% of drivers are facing traffic jams. The traffic line was once out of control.

2 The comprehensive evaluation of the location of traffic safety signs is accompanied by the acceleration of the pace of social and economic development. The number of vehicles in China continues to increase, and most people still learn to drive. In the future, the total number of cars will increase greatly. The growth rate of automobile quantity is proportional to the traffic accident rate. This is also a focus of current traffic engineering research in China. How to control the incidence of traffic accidents while keeping the growth rate of automobiles increases is a question worth pondering. After many years of practice, traffic safety signs have played a significant role in dredging and driving. The most simple words and symbols are used to transmit traffic information, which facilitates the driver's flexible control of the vehicle. This time, a comprehensive evaluation of the location of traffic safety signs is carried out to distribute the various signs in the best position to achieve the best traffic scheduling effect.

2.1 Traffic signage application status Traffic signs are specific information transmitted by graphical symbols and words. Luboan traffic facilities are used to manage traffic and indicate driving directions to ensure smooth roads and safe driving. Applicable to roads, urban roads and all special roads, with the nature of laws and regulations, vehicles and pedestrians must abide by. Up to now, China's traffic sign application program has become increasingly mature. Most of the regional traffic departments have begun to set signs according to actual road conditions, which are used to provide guiding services for vehicle driving. The first-tier cities took the lead in implementing the “signage-based” management model, setting different signs on the roads with more traffic flow, and setting up a self-service guidance system for car-passing.

2.2 Scientific methods for setting safety signage At present, social transportation is very fast in terms of development and construction. Many landmarks will have traffic signs at intersections, which will often give us more convenience. Along with the economic progress, people's highway development speed is also developed according to international standards. All road signs will have English translations on them, as well as the conformity of the national form. In fact, the signs of common practice will gradually become a development trend. As far as China's transportation industry is concerned, the safety signage needs to be combined with different traffic routes, focusing on two aspects: commercial area and school district.

Business district. The business district is a relatively densely populated place, and is concentrated in the relatively prosperous areas of the city. It is essential to set a safety signage at this location, otherwise it will cause a coherent traffic accident. Therefore, the signage setting in the commercial area must be “obvious” to be quickly observed by the consumer, so as to play a warning role. For example, parking lot signs are often set at higher positions, such as setting the sign as far as possible in the most conspicuous position. From the inspection of the commercial district, the domestic formal business district has set up special signs to guide the driving shoppers to accurately park the vehicles.

School district. In recent years, students have become “vulnerable groups” in the transportation system. Many students are injured and killed in traffic accidents, which is worth pondering for the domestic transportation industry. The most important location for setting up traffic signs in the school district is the increase in the number of students at the “road junction”. Drivers often ignore the danger of students entering and leaving the intersection, and fail to slow down in time to cause traffic accidents. School traffic warning signs must be set at intersections, erected on buildings or railings on both sides of the road, and set signs such as slow down at 50~100m from the intersection of the school.

2.3 Traffic Safety Signage Inspection Suggestions In different countries, no matter which kind of transportation facilities or other environmental characteristics, they are basically different from those who are temporary residents. In order to develop a better traffic environment, it is more convenient for passers-by to distinguish. The city's display cards are recommended to be translated in English and Chinese. In the same country, the same area should be selected. Due to the regional economy and other aspects, the implementation of the 3 information management system 3.1 The method of project division and the method and standard of standard engineering division directly affect the minimum unit of measurement of engineering quality, which is the engineering information index and engineering information tree of engineering quality management. Therefore, in the implementation, we should focus on the engineering quality division method we define in the system.

Each contractor can independently divide the unit project. All the middle bridges, separate interchanges and pedestrian bridges in the bridge project are combined into one unit project; every 1 ~3km of roadbed earthwork, drainage works, culverts, masonry works, etc. For a branch project, large values ​​should be taken as much as possible. When dividing the sub-projects it contains, the integrity and continuity of a natural slope or a fill roadbed should be fully considered, and artificial splitting and truncation should be avoided as much as possible. The bridge project is divided into foundation, lower structure, superstructure, protective engineering, and four types of distributed engineering. The superstructure prefabrication and installation are divided into sections according to each beam. Rebar processing and installation, table (wall) backfilling, prestressed tunnel grouting are controlled according to the process, and no sub-projects are carried out; after the sub-section engineering information is divided, the data is summarized and submitted to the director's office, and the director's office and the central laboratory Conduct a unified audit and define a uniform numbering rule; the director's office will issue the audited project information to each construction unit and enter the project quality management stage.

3.2 Authority Setting During the implementation of the platform, the allocation of rights is the focus of the work. The important personnel involved in the distribution process include the following aspects.

Construction unit laboratory director, tester, data officer; resident supervision test supervision, site supervision; central laboratory director, test and inspection personnel; 3.3 data sharing method data sharing method is an important form of interface between data, but also directly affects data Access speed. During the implementation process, we have two levels of database, the following are the following.

(1) Firstly, arrange the own data storage database in each construction unit on the bottom floor; arrange the summary database in the central laboratory, and save the entrusted and sampling data at the same time; in the director's office layout center database, the audited data can be directly uploaded to the central database. The construction units and supervision units may also upload the audited data directly to the central database.

3.4 Network Environment According to the two-level data distribution mode of the platform, the network environment of the platform needs to configure at least the central database server, and the terminal terminal accesses the data server. At the same time, the WAN and LAN office environments are required, and each operating unit can form a small-scale data sharing inside, and can also upload data through INTERNET browsing. Therefore, during the implementation process, the network environment should be fully checked, the database connection should be configured, and multiple data transmission parties should be provided.

4 Conclusion An important part of highway engineering construction technology management is highway engineering test and inspection. Highway test and inspection is also an important means of quality control and completion acceptance during the construction process, speeding up the progress of the project and improving All aspects of project quality, promotion of highway engineering construction technology and reduction of project cost have played an important role. In order to ensure the quality of construction engineering, it is necessary to carry out test and inspection of highway engineering. The information management of highway transportation is an important part of highway engineering. In actual work, it is necessary to vigorously promote traffic informationization and hope to realize the leapfrogging of transportation industry. For development, it is necessary to implement information management for highway test and inspection.
