Study On The Criteria And Indicators For Application Highway Reconstruction

In recent years, the rapid growth of traffic volume of highway in our country, with cumulative traffic volume and total axle load number increase, the road using performance declined, resulting in the many existing highway can not meet the growing traffic demand, need through the highway expansion to improve the capacity and level of security. Based on the background of Tongliao to Lubei section of highway extension project of highway reconstruction and extension time determination, evaluation and improvement of the problems during the construction of road, traffic organization, specifically in the: investigation and analysis of domestic and foreign highway expansion situation, from Tongliao to Lubei section of highway, combined with the expansion dynamic summary change and expansion of existing problems; using "four stage method" to predict the characteristics of traffic volume calculated and a comparative analysis of the predicted features in the expansion of the service level, for the road change could provide the basis for the determination of the timing of expansion; survey from Tongliao to Lubei section of road conditions and the status quo evaluation, analysis of the existing road traffic problems and potential safety problems, and put forward the improvement mea sures; describes the road expansion during traffic organization principle, from Tongliao to Lubei section of the road, combined with the renovation and expansion of the actual situation of the traffic organization scheme during construction is proposed.
