Starting from the existing evaluation system of asphalt pavement, single evaluation index and the comprehensive evaluation index are evaluated respectively. Based on engineering examples, this paper puts forward that the weighted geometric mean generation is to optimize the existing weighted arithmetic...

A model for network vulnerability evaluation based on cumulative prospect theory is proposed for more accurate evaluation of the effects of travelers’ behavioral responses on road network vulnerability caused by link closure. In the proposed model, the effects of both demand variations and travelers’...

this paper mainly introduces the harm of road and bridge pavement and subgrade settlement,expounds the causes of uneven pavement and subgrade settlement on the settlement road and bridge,analyzes the structure design of settlement road and bridge and finally discusses the construction technology for...

According to the data of 107 National Highway Luogang section of Guangdong vehicle load survey, By using theory of probability and statistics, the parameters such as gross vehicle weight, axle load, wheelbase, vehicle spacing and so on, are statistically analysed in this paper so as to confirm the probability...

The measured settlement curves of high-speed railway are presented with the characteristic of "small scale, large fluctuations", which is difficult to reach the requirements of curve regression coefficient with 0.92 on specification. This was done by adopting the method of mathematical simulation and...

To study on the chemical effects on Nanning expansive soils the lime, cement and fly ash were utilized as modifier to treat three different kinds of expansive soil. The fundamental engineering properties of expansive soil were analyzed to evaluate the improved effects and adaptability. The results indicate...

Due to poor performance of supply chain members the paper has been studied supply chain contracts based on newsboy model without option and centralized decision-making model. This research paper presents how to coordinate the supply chain in two-level of supply chain. All the numerical part analysis...

Sand liquefaction is a common seismic hazard of foundation. In order to investigate the hazard evaluation criteria of liquefaction of sand soil foundation, a research was made to study different methods of discriminating sand liquefaction with the reference of the results of recent related studies in...

At present, there exist some problems of energy conservation and emissions reduction in tunnel and underground engineering construction. During the operation period the current situation of the energy conservation and emissions reduction in tunnel and all kind of underground space can not be ignored....

A parameters optimization model (POM) of stagger-luminaire-distribution (SLD) lighting for tunnel interior zone was established to acquire the most energy-saving luminaire installation parameters (LIPs) of highway tunnel interior zone, with luminaire installation height, longitudinal installation spacing,...

This paper studies optimization of train diagram with different speed of high-speed railways, and introduces soft time window to construct the optimization model of train diagram, aiming at minimizing the difference between the arrival and departure time of the trains and the expectation of passengers...

In order to adapt to the complex traffic and reduce the delay brought by simple traffic model, an improved adaptive genetic fuzzy control method was put forward for intersection traffic signal control. In order to improve the computational efficiency , the population size should be adjusted and the Gaussian...

Summarizing the existing rigid-flexible composite pavement structure types in service, the paper recommends two pavement structures , adopts the method of expert evaluation of index quantification, sets up the quantitative evaluation model for asphalt pavement structure layer selection and works out...

Accurate measurement of passengers’ walking speed is significant for evaluating and optimizing service level of the facilities in transfer stations. This paper studies the walking speeds of various transfer passengers on the upstairs of Beijing Haidian Huangzhuang Subway Station during evening peak hours...

In order to get the relationship between China’s carbon emissions and transportation industry, we calculate the growth rate of carbon emissions and freight turnover based on the time series data from 1982 to 2014, showing them by the line chart. According to the change of the growth rate, carbon emissions...
