Officials said it's a pilot program, and more could be installed if they're successful.
Studies cited by the town show flashing signs make drivers more likely to yield to pedestrians.
The first signs will be installed at:
- NW Maynard Road at the entrance to Godbold Park as part of the Black Creek Greenway.
- West Dynasty Drive near Sudbury Drive as part of the Black Creek Greenway.
- Jenks Carpenter Road near Fryars Creek Drive as part of the White Oak Greenway.
- Morrisville Parkway near East Ferrell Road as part of the American Tobacco Trail.
Each sign costs about $19,000 to install and maintain. 80 percent of the cost is covered by a federal grant.
