Abstract The invention relates to methods and systems for alerting worksite personnel to oncoming vehicles. Although generally, a speed limit is enforced in the vicinity of worksites not all drivers obey this speed limit. Therefore the invention includes an alert system comprising a controller, a vehicle speed sensor configured to generate speed measurements of oncoming vehicles and to communicate said measurements to the controller, a vehicle warning display configured to receive display instructions from the controller and to, in response, display a vehicle speed warning, and one or more local alert devices, locatable remotely to the vehicle warning display, configured to receive local alert messages from the controller and to, in response, make a local alert.
