城市道路交通色彩的安全评价及调和

Risk assessment and harmony of urban road traffic colors

为实现城市道路交通色彩的安全与和谐美观,降低交通事故,建立和谐美观新城市,进行了城市道路交通色彩的定量化研究。通过交通问卷调查和现有研究成果,综合系统工程学,提出城市道路交通色彩评价指标体系,并在此基础上构建GT-GA-BPNN的联合交通色彩评价模型。通过现代色彩理论和色彩心理学知识,基于孟塞尔和孟·斯宾瑟色彩理论构建了城市道路交通色彩调和优化模型。最后,通过构建徐州市城市道路算例,使用MATLAB,EXCEL等软件进行运算,验证了以上评价指标体系和评价、优化模型的有效性和科学性,提出相关改善建议。

To improve safety and harmony of urban road traffic color, reduce traffic accidents and establish a new beautiful harmonious city, the urban road traffic color is researched quantitatively. Grounded on traffic questionnaires and existing research results and combined with the system engineering, the urban road traffic color evaluation index system is put forward, and then based on it; a GT-GA-BPNN color evaluation model is constructed. Making use of the modern color theory and color psychology knowledge and based on Munsell and Moon-Speneer color theory, a urban road traffic color harmony optimization model is also constructed. Then, take Xuzhou city road as an example, using MATLAB, EXCEL and other software, to verify the effectiveness and scientificity of the evaluation index system, the evaluation model and the optimization model above. And finally, put forward some related proposals.
