A friend posted about the current initiatives in the US as they embark on revising their Manual on Uniform Traffic Control Devices (MUTCD). This manual along with AASHTO’s Geometric Design of Highways and Streets and their Highway Capacity Manual are something like the holy trinity for Highway and Traffic Engineers. These are also the main references for our DPWH for the manuals and guidelines we use in traffic and highways.
Here are a couple of articles calling for the revisions to reflect recent designs mainly from NACTO, which itself publishes guidelines for roads to be more inclusive rather than car-centric:
NACTO (May 2021) Modernizing Federal Standards: Making the MUTCD Work for Cities, https://nacto.org/program/modernizing-federal-standards/
NACTO (May 11, 2021) A Blueprint to Update America’s Street Manual, https://nacto.org/2021/05/11/a-blueprint-to-update-americas-street-manual/
We don’t have to pattern revisions after the MUTCD but then that requires that the DPWH through its Bureau of Research and Standards (DPWH-BRS) do its part in compiling, reviewing, studying and adopting materials from various countries, and developing suitable standards and guidelines for roads in the Philippines. Do they have to reinvent the wheel? Not so and they can still refer to the US manuals as long as again these are localised for our conditions and situations.
