The aim of this research is to develop a new evaluation method for shared use of bicycles and pedestrians from a view point of their comfort, and to propose the level-of-service of sidewalks with shared use of bicycles and pedestrians which are mainly adopted in Japan. Results from this research are as follows,1) Risk-perception model for mixed traffic (2000-2001) : The risk perception model was developed through off-road experiments, which can estimate the risk perceptions in the conflicts of bicycles and pedestrians, by using their relative position and speed.2) Evaluation of shared use traffic (2001-2002) : By employing this model, the evaluation index for mixed traffic using video survey was proposed. The index presents the predicted frequency of near-miss between cyclists and pedestrians and between cyclists.3) Level-of-service system (2001-2002) : A new level-of-service system for shared use of bicycles and pedestrians by employing near-miss prediction model, is also proposed. It can be clarified that the index shows clear relationship to traffic density, bicycle speed, level of safety sense of road users.4) Evaluation of bicycle lanes on shared use sidewalks (2002) : The proposed level-of-service system are applied to evaluation of four cycle lane projects on shared use sidewalks and a shopping street. Colored cycle lane shows effects on separation of pedestrians and bicycles and improvement of level-of-service.

本研究的目的是从自行车和行人的舒适性角度提出一种新的自行车和行人共享使用的评价方法，并提出日本主要采用的自行车和行人共享人行道的服务水平。研究结果如下：1)混合交通风险感知模型(2000-2001)：通过路外实验建立了混合交通风险感知模型，可以利用自行车与行人的相对位置和速度来估计自行车与行人冲突时的风险感知。2)共享交通评价(2001-2002)：利用该模型，提出了视频调查混合交通的评价指标。3)服务等级系统(2001-2002)：提出了一种新的共享单车与行人共享服务等级系统，并利用该模型提出了一个新的共享单车与行人共享服务系统。可以明确的是，该指标与交通密度、自行车速度、道路使用者的安全感水平有明显的关系。4)共享人行道自行车道评价(2002)：将提出的服务等级体系应用于共享人行道和一条商业街上的四个自行车道项目的评价。彩色自行车道对分隔行人和自行车，提高服务水平起到了一定的作用。
