Function‐Valued Marked Spatial Point Processes on Linear Networks: Application to Urban Cycling Profiles

ABSTRACT In the literature on spatial point processes, there is an emerging challenge in studying marked point processes with points being labelled by functions.

Summary:ABSTRACT In the literature on spatial point processes, there is an emerging challenge in studying marked point processes with points being labelled by functions. In this paper, we focus on point processes living on linear networks and, from distinct points of view, propose several mark summary characteristics that are of great use in studying the average association and dispersion of the function‐valued marks. Through a simulation study, we evaluate the performance of our proposed mark summary characteristics, both when marks are independent and when some sort of spatial dependence is evident among them. Finally, we employ our proposed mark summary characteristics to study the spatial structure of urban cycling profiles in Vancouver, Canada.
