Traffic signing is a critical part of the transportation
system and one of the primary formal means
of communicating information to road users. Signs in
a nearby Major Traffic Generator (MTG)
area are more special than other places as the
private sectors are willing to have their commercial
symbols to be installed. Since traffic generators are
major regional attractions, events, or
facilities which attract persons or groups from
beyond a local community, city, or metropolitan area,
suitable designed commercial symbols are able to help
communications between the
motorists and the generators. Currently, the guidance and
manuals on MTG guide signing may
not all fit to the actual needs and be suited to the
drivers' psychological and driving behaviors. This means
there is a need to establish the eligibility criteria,
warranting procedures, and
thresholds associated with guide signs for MTGs. The
research objectives are (1) evaluate the
drivers' driving and psychological behaviors under
different designs of symbols for Major Traffic Generators;
(2) simulate and examine the operational and safety impacts
of symbols with commercial
symbols; and (3) develop warrants of symbols for Major
Traffic Generators. By this
proposal, not only the conventional ways of realizing these
types of warrants are proposed, but also the advanced
driving simulator that TSU owns for the research team to use
will be employed as a tool to
simulate the impact of various symbols for the drivers'
behaviors.
