Field testing anti-speeding messages
Submission Date: 2019
On a 60mph section of road that included a 40kph school zone, speed detection devices were installed prior to, immediately after, and further away from variable message signage (VMS) displaying anti-speeding messages. Speed data (>250,000 vehicle movements) were collected continuously prior to VMS installation (week1), during message display (week2), and post-display (week3). Speed reductions associated with VMS deployment from week1 to week2 were partially sustained at week3.
