Have you perhaps considered social media- google alerts have alert notices issued hourly, for example accident on X road, and are received direct to the users mobile device. I would also consider contacting any AA equivalent or large tow truck agencies as they may have a regualr pick up spot as such. Best of luck
@ Lipika Deka...data available from police is spot where accident occurred, time, person and vehicle involved, injury type....actually i wanted to use neural network analysis for identification... along with data from police
