The Effects of Rainfalls on Expressway Travel Time
Authors: Shi Li Juan , Jing Ting , Chen Xiao Hong , Ou Dong Xiu
Published: August 2013

This paper presents an investigation of the effects of rainfall with different levels of precipitation intensity on urban expressway travel time under free-flow speed conditions. The traffic data and corresponding weather data from the expressway section of Longyang in Shanghai for more than one year were used. Statistical analysis was applied to investigate the effects of rainfall on travel time quantitatively. There are two major contributions of this paper. Firstly, four levels of rainfall have varying degrees of significant impacts on travel time in terms of average travel time. Slight rain has no influence on variability of travel time, while heavier rain increases the variability. Secondly, three travel time stochastic models: Normal, Lognormal and Weibull, were proposed. The Lognormal model is the best-fit model under good weather, slight and moderate rainfall conditions, while both Weibull model and Lognormal model are the preferable models under heavy rain and rainstorm conditions. The recommended Lognormal model can be further used for evaluating the performance of the Longyang expressway section in terms of travel time reliability under good weather, slight rain, moderate rain, heavy rain and rainstorm conditions respectively.

Published: August 2013

The tidal stream kinetic energy can be abstracted by the horizontal axial turbine, and most concentrate closing to seaside, where the tidal stream turbine must work near the free surface. The interaction between wave surface and the turbine will affect the turbine performance. In this work, the performance of tidal stream turbine working beneath the free surface was simulated, and the wave was discussed. The results indicated that the turbine depth Fr number is the main factor that affects wave induced by the turbine. As the turbine depth Fr number is less than 1.0, the wave is not apparent, and as the Fr number increased, the wave height rose. By the analysis of turbine performance, it is discovered that the wave will influence turbine efficiency, but the relationship between wave height and turbine efficiency is not regular.

Traditionally, assessing impacts of urban land use on thermal environment is mainly depended on statistical analysis, which cannot exactly express the internal spatial correlation fundamental between urban land use and thermal environmental effects. This study introduces fractal theory to build radius dimension, and makes a quantitative description of the characteristics change from the center of the urban heat island effect on land use spatial pattern to the surrounding. The results suggested that those radius dimensions of five typical land use types are ranked in descending order: cropland, forest, water, bare land and built-up. It is indicated that built-up has positive effect on the performance of urban thermal environment, while forest, cropland and water have negative effect on urban thermal environment. The effect of bare land is not obvious. It is demonstrated that the radius dimension can effectively distinguish the gathered or mitigated effects from various land use spatial structure on urban heat environmental effects, which scientifically guides government to mitigate the UHI extant and degree by urban land use planning.

For the water pollution problem in the wetland of Xiquan Lake in Shenbei of ShenYang, we carried out the degradation and adsorption expriements of three nitrogen and explored the law of them. We collected the soil and indigenous plants at the scene, by measuring the growing season and non-growing season soil and plant removal rate of ammonia nitrogen,nitrate and nitrite nitrogen, analysis the degradation and adsorption law of the wetland soils and plants for the three nitrogen. We take use of the reaction rate equation to calculate the two growth cycle average coefficient of the degradation and adsorption. The results show that the soil and plant can take in some of the three nitrogen. When the adsorption reaches the saturation, they come to dynamic equilibrium.

Authors: Chen Cong Cong
Published: August 2013

The ecological groin being built using elastic filter bulb with biologic filler, has received attention in the community for its role in improving stream water quality through altering stream hydrodynamics, intercepting sediment and thereby reducing the sediment-attached nutrients. As an important watercourse for the project Transferring Yangtse River into Taihu Lake, Wangyu River, was chosen in this study to investigate the effect of ecological groin based on two sampling campaigns in April 2012. The results showed that suspended solid (SS) and total phosphorus (TP) concentration in the water decreased significantly after the ecological groin. The SS and TP concentration in the surface, intermediate and bottom water decreased after the ecological groin by 53.5% and 12.7%, 44.0 %and 14.5%, and 35.5% and 9.3%, respectively, which were greatly related to the facts that ecological groin favored sedimentation and that the total particulate phosphorus accounted for up to 75.0% of TP in the water. Comparatively, TN concentration in the surface, intermediate and bottom water decreased after the ecological groin by 5.6%, 2.4% and 5.1%, respectively. The findings of this study enable us to gain insight into the role of ecological groin in improving river water quality.
