Digital and projected advertising displays (DPADs) use light-emitting diode (LED) technologies to
\ndynamically change message content and have the capability of displaying high quality video and
\nanimation on billboard-size screens. The rapidly decreasing cost of DPADs since the mid-2000s has led to
\nincreasing pressure on governments to approve their installation adjacent to roads. Although the effect of
\nstatic roadside advertisements on driver distraction and road safety has been researched since the 1930s,
\nthe effect of digital and dynamic advertising on road safety is still inadequately understood. Many
\njurisdictions, both in Canada and worldwide, have struggled to regulate these signs due in part to their
\nrapid market penetration and the lack of information regarding their impact on road safety. This has
\nresulted in some jurisdictions instituting a moratorium on DPADs, others attempting to regulate DPADs
\naccording to existing static advertising sign by-laws, and others creating new by-laws specific to DPADs.
\nThe Transportation Association of Canada (TAC) recognized the need for national guidelines to help
\ngovernment agencies regulate DPADs from a road safety perspective. This paper presents preliminary
\nresearch findings from a literature review and advertising sign industry representative interviews which
\nwere used to develop these guidelines. Specifically, it discusses the following six issues to consider to
\nhelp jurisdictions develop transparent, consistent, reasonable, and flexible DPAD regulations: (1) DPAD
\nconspicuity, (2) sight distance measurement, (3) differentiating between on- and off-premise DPADs, (4)
\ndefining animation exemption zones, (5) DPAD proximity to traffic control devices, and (6) DPAD
\nproximity to key decision-making points. Since this paper is based on ongoing research, it provides
\ninformation for each of the six issues \u2013 it does not provide recommendations (these will be included in the
\nforthcoming guideline) and does not necessarily represent the views of TAC.<\/p>\n
