Traffic signs and pavement markings are intricate traffic control devices that by simple display are used to regulate, warn and guide traffic on streets and highways. Traffic signs are used to convey a variety of messages to the road users. As speeds and volumes of traffic have increased over the years, the complexities of providing the messages will increase accordingly. General pavement markings consist of lines, longitudinal or transverse, as well as symbols and words that are applied to the pavements. To command the road users’ attention, traffic signs and pavement markings must have the fundamental qualities of conspicuity, legibility and recognition.
In Canada, the principles and standards governing traffic signing and pavement marking applications are set out in the Canadian Manual of Uniform Traffic Control Devices (CMUTCD). Per the CMUTCD, traffic control signs are classified into five categories as regulatory signs, warning signs, guide signs, emergency management and civil defense signs, and school signs, while pavement markings are categorized as one of the following five classes as longitudinal, lateral, merging/diverging, symbols and letters and special situations (types).
EASL Transportation Consultants, Inc.’s design team is familiar with the signing and pavement marking standards by Alberta Transportation including those contained in the “Highway Guide and Information Sign Manual”, as well as those local design standards by the most major cities and municipalities across the province. Our firm is experienced in undertaking signing and pavement marking design for various traffic and transportation improvements projects for both the private and public sector clients in Alberta, elsewhere in Canada, as well as in the US.
In addition, there are unusual traffic circumstances that require exceptions to the standard rules, hence demanding special attention and engineering judgment from the design professionals. EASL Transportation Consultants, Inc. has experience in completing signing and pavement marking projects of unusual designs where professional engineering judgments and practical experience are exercised to supplement the standard design guidelines.
