Research On Express Way Landscape Evaluation Method Kunming

With the development of national economy, greatly accelerate the urbanizationprocess. The rapid expansion of cities brought a series of traffic problems, the trafficcongestion in many cities, congestion. In order to alleviate the traffic pressure on urbanareas, to adapt to urban development, many cities began planning and building roads toimprove the speed quickly, shorten the running time, the efficiency of transportation. Rapidconstruction of urban road system is mainly to improve the capacity of urban road networkto ease traffic congestion, rapid distribution of traffic, as vehicles to provide safe, fast,efficient, comfortable and convenient driving environment. In China, the landscape ofurban expressway is still in the exploratory stage, especially as the construction ofKunming Expressway this initial stage of the city, while easing traffic congestion,landscape design is very important. Therefore, the landscape of urban expressway hasimportant theoretical significance and application value.This paper studies include: the basic concepts of landscape Expressway andExpressway landscape features and landscape assessment of visual theory, based on theSecond Ring Expressway, Kunming heterozygosis around the space, lighting andinterchange points for the investigation and the status of analysis, and composition andelements of the landscape and visual assessment indicators were selected, based on indexsystem construction principles, methods, combined with fast road landscape elements ofthe analysis of highway construction in Kunming Erhuan landscape evaluation indexsystem, and finally, the use of levels analysis and fuzzy comprehensive evaluation methodto Kunming, the Second Ring Expressway as an example to specific evaluation andanalysis. Conclusions drawn in the following aspects:(1)In the express, landscape comprehensive evaluation value show the second southring road＞the second west road＞the second north ring road＞the second east ring road.(2)With this evaluation method can identify weaknesses in a landscape of a section ofitems, such as in the East Second Ring Road, the landscape quickly fuzzy comprehensiveevaluation process, found that evaluation U123(road noise with the settings) scored lower,its Index U12greater impact at higher levels, leading to the evaluation results for thegeneral as a major factor. The western section of the Second Ring Expressway evaluationU231(the road on both sides of building shape and color) and U243(environmental damagedegrees) lower scores, U23and U24on the higher index greater impact.(3)From the overall landscape of the evaluation results can be seen and the landscapeof each section there are differences between indicators of and can reflect the specific points of difference and the degree of difference. For example, the southern section of theSecond Ring and Fast Ring Road East differences quickly, quickly in the southern sectionof the Ring, the road noise with their own settings and green and there are differences.(4)Meanwhile explain use the AHP and FCE are feasible for Kunming expresswaylandscape evaluation. It can quantitative reflect the landscape evaluation level and inindividual event index landscape level, it has comparability. The results can accuracy andobjective reflects the practical situation of road landscape. This method simple and easy todo, with practicability.(5)Meanwhile, this text establishing evaluation system and the evaluation method canput forward improvement measures for completed the expressway, and provides thedecision for not construct. It has a profound effect on Kunming expressway design,construct, management, maintenance and so on.(6)Finally, the status of the investigation plot analysis and evaluation, integratedurban freeway landscape features and planning principles, Kunming expressway proposedlandscape optimization tips:①Lighting：Shape of lamp posts, lamps and road shape to match the nature and thebuilt environment, transportation corridors Fast Way requires a simple style lamp posts andlamps light elegant, suitable for faster traffic environment with modern high-rise buildingson both sides style of coordination.②Traffic marking：Flag set should consider the sign board in the font size, color andcolor contrast, to increase its recognition properties, directional signage should be clear,can not bring chaos to the driver information.③Building and Road Alignment：Buildings along the road on both sides to have acertain distance between each other, there must be is virtual, help strengthen the activitiesin the sense of movement on the road and a sense of rhythm. Combination of buildingspace to each other to coordinate, complement each other, the main access to a variety ofeffects.④Green：Convex curve on the road and planting tall trees on the vertical curve mayindicate changes in route, induced a good line of sight. In the city, due to vehicle exhaust,dust pollution is serious, poor soil texture and water supply factors such as the existence ofdifficulties, so the choice of plants, according to the ecological conditions of the specialroad, should choose plants with strong resistance, First select the main native species, the main tree species should have stronger anti-pollution ability to adapt to rapid road greenfeatures. Both sides of the overpass and road base railing planters, planted woody,herbaceous plant or some vertical climbing plants, so plant the branches of natural droop.General on the median of thin soil, so green light should be used when the root of the plant,while plant must have a strong resistance to drought and poor soil capability.⑤Subsidiary structures：Ancillary facilities, including noise walls, power lines. Theseancillary facilities should be coordinated with the overall road and in harmony with thesurrounding environment. Noise wall must be continuous, not benzene and monotonous,the use of road who has a good visual impression.In summary, this paper quickly through the Second Ring Road, Kunming, field surveyand evaluation of landscape analysis, the Second Ring Expressway Kunming point of viewof the differences and inadequacies, and make optimization recommendations. And hopethat these findings and recommendations for optimization of Kunming expresswayconstruction landscape will provide some help and learn.
