“创意产业园区”景观规划设计的构想

近年来，在中国许多特大城市、大城市中不断出现了创意产业，形成了当下特有的“创意产业园区”现象.研究表明：城市产业结构的变化在客观上为“创意产业园区”的出现提供了先决条件，“创意产业园区”的形成还与就业机制的变化、政府的推动成正相关系.“创意产业园区”是带有创意行为的景观规划设计，是建筑群体风格、单体建筑、室内外环境、节点空间等景观的可识别性创造.“创意产业园区”必须加强景观的规划与管理.     

平顶山市环境空气容量与污染物排放量的关系研究

确定了平顶山市区环境空气容量,建立了工业生产总值与环境空气主要污染物排放量的数学模型,从而定量讨论了环境空气容量与主要污染物排放量的关系.其中,工业生产总值与二氧化硫排放量的拟合方程为Y=0.013 8X+2.57,与可吸入颗粒物排放量的拟合方程为Y=0.005 70X+2.59,经检验,两方程均呈显著性线性关系.利用此方程,预测了未来的污染物排放量,并与不同城市面积下的环境空气容量进行了比较.结果表明,即使城市面积发展到200 km2,两种主要污染物排放量也已经超过大气环境空气容量.

Development of the Driving Simulation System MOVIC-T4 and Its Validation Using Field Driving Data

Underground urban expressways are a possibility for solving many existing transportation-related problems, such as traffic congestion in high density areas and the division of neighborhoods due to elevated roadways. However, they may also pose high risks regarding traffic safety. Therefore, it is important for a pre-analysis of traffic safety to be made. This paper describes recent efforts to develop a driving simulation system, MOVIC-T4, for traffic safety analysis of underground urban expressways. In order to develop a small portable simulator, a small-sized motion-base with two-degrees-of-freedom is used to duplicate accel-eration cueing together with a head-mounted-display (HMD) for the visual system. An overview of this sys-tem is given and the reliability of driving data obtained from the experiments using MOVIC-T4 is discussed through a validation study using field driving data. The results of validation indicate that the perceived speed, distance headway, and physiological data in the simulator show the almost same trend as that in the real world, but larger decelerations tend to be produced in the simulator.     

Urban Railway Accessibility

Effective use of urban rapid railway systems requires that the railway systems be effectively con-nected with other transportation modes so that they are accessible. This paper uses the logit model and data to analyze the factors influencing railway access choices in a railway choice access model. The results indicate that access time, access cost, and access distance are factors significantly affecting railway access choices. The user’s income significantly affects the probability of choosing to walk rather than to take a taxi, but is not related to choosing buses or bicycles. Vehicle ownership significantly affects the probability of choosing a taxi, but is not significantly related to the other modes. The conclusions provide an analysis tool for urban railway planning and construction.
