WebMany agencies also use these signs to display behavioral traffic safety messages (BTS). Several studies investigated the usefulness and effectiveness of VMS safety messages, in particular, how the messages influence driver behavior, how attentive the public is to the message, and ways agencies could optimize safety messages on VMS. WebThis report analyzes the impacts that might be expected from the adoption of proposed minimum maintained retroreflectivity levels for traffic signs to improve night visibility. The report evaluates the broad spectrum of concerns expressed by State and local agency staff at four workshops held during the summer of 2002.

WebHowever, most drivers do not slow down in response to these static speed control measures. The changeable message sign (CMS) with radar unit has dynamic capabilities which may be more effective in altering driver behavior. The radar, attached directly to the CMS, determines the actual speed of individual vehicles in the traffic stream. WebThe effects of sign luminance on detection and recognition of traffic control devices is mediated through contrast with the immediate surround. Additionally, complex visual scenes are known to degrade visual performance with targets well above visual threshold. countertop dining set
