## Main Question or Discussion Point

Hi everyone,

My data consists of road accidents and spatial covariates. Originally i wanted to apply an inhomogenous Poisson process with covariates. Then I realised that the accidents cannot occur everywhere in space, but only on roads. I found an example, that is quite similiar to mine. it is said there, that one may model a Point process on a network of one-dimensional lines. Unfortunately it isn't given any more information. I searched the internet for it, but wasn't able to get information, how to explicitly model this.

The area of interest is 70.000 square kilometers and the coordinates of all roads are given.

I would deeply appreciate it, if somebody gave me a hint and/or name some literature on how to tackle this!

Thank you very much in advance!

Regards

Nemorad
