不同降雨强度下居民出行转化为公交的研究

Study on resident trip into public transport under different rainfall intensity

降雨影响着居民出行方式的选择行为,而降水等级的不同对居民出行方式的影响也各不相同,因此,降水日道路交通状态与其他时间有明显差异。通过对在不同降水等级下的出行意愿以及出行方式调查,分析居民在不同出行目的、年龄、经济情况与不同降雨强度下公交转化的情况,得出在不同的降雨强度下居民乘坐公交出行受到出行目的、年龄、经济的影响程度各不相同。并建立二元Logit模型来研究降雨条件下的公交出行方式选择,分析不同降雨强度条件下居民公交出行与出行目的、年龄、收入之间的关系,利用调查数据对参数进行标定,得出在不同等级降水下居民出行方式的选择随居民出行目的、年龄、经济不同以及降雨强度的增加而变化的规律。

Rainfall affects the behavior of residents ＇travel mode,and the difference of precipitation level has different influence on residents＇ travel mode. Therefore,there is a significant difference between the traffic conditions of precipitation and other times.In this paper,through the investigation of travel intention and travel mode under different precipitation levels,this paper analyzes the residents＇ conversion of public transport under different travel destination,age,economic situation and different rainfall intensity,and draws that residents travel by bus at different rainfall intensity. The purpose of travel,age,and economic impact vary.And establishes the binary Logit model to study the choice of bus travel conditions under rainfall conditions,analyzes the relationship between residents＇ travel and travel destination,age and income under different rainfall intensity,and uses the survey data to calibrate the parameters. The choice of residents ＇travel mode under the level of precipitation varies with the purpose of residents＇ travel,age,economic difference and rainfall intensity.
