Modeling Lane-Keeping Behavior of Bicyclists Using Survival Analysis Approach

Table 1

Analogy between lifetime data analysis and bicyclist behavior analysis.

	Lifetime analysis	Lane-crossing behavior analysis
Parameter	Time 𝑡	bicycle volume 𝑞
Failure event	Death at time 𝑡	Lane-crossing behavior at volume 𝑞
Variable	Lifetime 𝑇	Valid volume 𝑞𝑐
Censoring	Lifetime 𝑇 is longer than the duration of the observation	Valid volume 𝑞𝑐 is greater than travel demand
Survival function	𝑆(𝑡)=1−𝐹(𝑡)	𝐹lk(𝑞)
Probability distribution function	𝐹(𝑡)	𝐹lc(𝑞)
