Level of service appraisal method for shared use and design guidelines for various cycling spaces

本研究的目的是从舒适度的角度开发一种新的自行车和行人共用的评价方法，并提出日本主要采用的自行车和行人共用人行道的服务水平。研究结果如下：1）混合交通风险感知模型（2000-2001）：通过越野实验，建立了自行车与行人冲突的风险感知模型，利用自行车与行人的相对位置和速度，对自行车与行人冲突时的风险感知进行评估（2001-2002）：利用该模型，提出了基于视频调查的混合交通评价指标。3）服务水平系统（2001-2002）：通过采用接近事故预测模型，提出了一个新的自行车和行人共享使用的服务水平系统。可以明确的是，该指数显示出明确的关系，交通密度，自行车速度，道路使用者的安全意识水平。4）评价共享使用人行道上的自行车道（2002年）：建议的服务水平系统的评价四个共享使用人行道和购物街的自行车道项目。彩色自行车道对行人与自行车的分流和服务水平的提高有一定的作用。

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.
