COAST MERIDIAN / PRAIRIE INTERSECTION IMPROVEMENTS

Traffic Signal Timing

The Coast Meridian / Prairie signal has an existing intergreen clearance
period of 3.0 seconds. To comply with RTAC standards, this interval
should be increased to 5.0 seconds, (4.0s of amber and 1.0s of all red).

Speeding Traffic

I believe the RCMP currently does periodic checks of this intersection for
violations. They should be requested to continue with these checks,
especially for drivers speeding and running red lights.

Intersection Geometry

Hamilton has proposed geometric changes to this intersection as shown on
figure 3. These changes would include the reduction of lane widths and
the elimination of exclusive right turn lanes. The changes proposed are
likely warranted but can probably wait until redevelopment occurs adjacent
to the intersection.

Also croposed is the construction a centre median on Prairie, to restrict
left turus in and out of developments east of the intersection. Centre
medians on Prairie, at both sides of the intersection will definitely be
required as traffic increases in this part of the City. However, current
traffic levels do not place an urgency for this construction. The
inconvenience placed on the businesses and drivers may outweigh the safety
concerns at this time.

Pedestrian Head and Inductance Loop Installation

The traffic signal at the Coast Meridian/Prairie intersection lacks
pedestrian heads, The installation of pedestrian heads will improve the
efficiency of turn movements for vehicles, and ensure pedestrians have
cleared the intersection at the end of their signal phase.

The signal controller at this intersection is capable of fully actuated
operation but is presently set for two phase, fixed-time control. The
installation of inductance loops for each direction will reduce delays for
drivers, especially during off-peak periods.
