The purpose of this publication
is to outline recommended practices for ramp speed signing in a useful and
widely accepted form for Canadian practitioners. It has been primarily
developed as a reference document for traffic engineering professionals responsible
for selecting and implementing traffic control devices for managing speeds on
ramps.
Accurate, up-to-date and full
coverage of issues relating to ramp speed signing in Canada is provided. The
recommended practices have largely been created according to accepted human
factors principles defined by wide-spread use of guidelines across a variety of
Canadian jurisdictions. When possible, the documented practices provide
quantitative guidance for the use and placement of ramp speed signs and
associated devices.
The document also proposes an
amended version of a ramp advisory speed limit sign contained in TAC's Manual
of Uniform Traffic Control Devices for Canada (MUTCDC). The importance of
standards, uniformity and consistency is emphasized throughout the publication.
However, these tenets of road safety engineering should not be used in place of
sound engineering judgement.
