The Study Of The Legibility Of Traffic Signs In Highway Construction Work Area

With the rapid development of the transport industry, after the road opened to traffic, in the role of the increasing traffic load, highway and its supporting facilities will follow the emergence of various degrees of aging and damage, the road needs for maintenance or reconstruction. At the same time, with the rapid economic development and the continuous adjustment of industrial structure, a large number of roads need to keep upgrading and transformation. Alteration or expansion of highways will bring many problems. For example, traffic congestion, increased accidents, reducing efficiency and so on. Construction work zone traffic sign for the visual recognition of the effects of the construction work area to ensure traffic safety is particularly important.This paper identified the characteristics of drivers through questionnaires. In trucks and passenger, large passenger distribution center driver, the driver conducted a questionnaire survey. Based on the survey of the driver, according to the driver of the physical characteristics of the visual recognition of a summary of results of traffic signs to design of new traffic signs. Measured traffic conditions under the existing traffic signs, and analyzed traffic volume data. New traffic signs will be covered on the top of the existing traffic signs, Measured traffic conditions under the new traffic signs, and analyzed traffic volume data. Using cross method analysis design traffic signs and traffic signs under the existing differences in traffic volume. Summary of results, proposed as the recognition of traffic signs mix better. Optimization of traffic signs proposed.This article marked the color, content of traffic sign as the object of visual recognition. Traffic signs are discussed in detail elements of the logo as the effect of recognition. Optimization of traffic signs proposed. Provided practical basis for traffic signs optimize.
