As a result of the analysis undertaken for existing conditions, Bunt & Associates recommends the following improvements for short term (immediate) implementation:
Improvements
Involving Alberta Transportation:
|
Priority
#1: |
Closure
of 49th Street at Highway 12, the safety of access and turning
movements at Highway 2A and 49B/49C Avenues, and intersection safety at
the Highway 12/Highway 2A/railway crossing intersection |
This intersection will eventually need to be
closed for reasons of safety. However, to the extent that the Town and the
Province continue to monitor the intersection and to the extent that accident
rates remain low, the southbound right turn from 49th Street onto
westbound Highway 12 should be allowed to remain in place, though closure may be
dictated by the Province in the short term as a result of the widening and
re-construction of Highway 2A. If the right turn is allowed to remain after that
construction project is complete, then the intersection conditions will need to
be monitored annually in order to assess accident rates and to assess the point
at which the intersection should be closed. All of the other safety issues in
this area will be dealt with as part of the re-development of Highway 2A as
currently planned by the Province, though it is noted by Bunt & Associates
that the operation of the 49B/C intersections at Highway 2A will continue to be
awkward, and further that increases in traffic volumes to the 20,000 population
horizon may result in the necessary closure of one or both of these
intersections.

Priority
#2: |
Intersection
Congestion and Upgrading on Highway 2A at Wolf Creek Drive |
Traffic signals should be installed at this location as a high priority so as to address safety issues as they relate to trucks turning out from Wolf Creek Drive onto Highway 2A. Geometric improvements are also required, specifically the addition of northbound and southbound right turn lanes as illustrated on Exhibit 4-4A. Note that further improvements to the intersection of Woodland Drive/Service Road will be required at a later date, as outlined in the Long Term Recommendations section of this report.
Priority
#3: Highway 2A Service Road between 54th
Avenue and 63rd Avenue
The issues at the Woodland Drive intersection were discussed previously as part of the upgrades recommended at the Woodland Drive/Highway 2A/Wolf Creek Drive intersection. As such, Woodland Drive will not be included here as part of the discussion of the service road intersection improvements.
Both the 63rd Avenue and Dicken’s Lane intersections with the service road function as Type I intersections with approximately 25 metres of separation from Highway 2A. As such, neither intersection requires upgrading to Type II or III unless on-going monitoring of accidents indicates the need for improvements in advance of being warranted based on traffic volumes. In the case of Heritage Way, an upgrade to a Type II design is required immediately along with select geometric improvements as illustrated on Exhibit 4-4B.
Priority
#4: Traffic signal requirements at Highway 12/C&E
and/or Highway 12/53rd Street
Traffic signals should be installed immediately at the Highway 12/C&E Trail intersection so as to improve accessibility to the hospital on C&E Trail south of Highway 12, and to promote C&E Trail north of Highway 12 as the main north/south corridor within the Town as recommended in the long term road network.

Priority
#5: |
Upgraded
intersection design on Highway 12 at West Side Road, the Lacombe Golf
Course, 45th Street, East Side Service Road and Wolf Creek
Drive |
Geometric improvements are currently required at
the Lacombe Golf Course access, and improvements to the other intersections
noted will be required by the 20,000 population horizon. It is recommended that
the existing east golf course access remain as an entrance to the facility, but
that turning movements be limited so as to prohibit eastbound left turns in to
the access. Concurrent with this improvement, the existing exit should be
relocated
to the west so as to be placed at the crest of the rise on Highway 12. This
access should then be configured to allow all in and outbound movements to and
from the golf course and other uses in the area. This is illustrated on Exhibit
4-6 in this report.
Town
of Lacombe Improvements:
5-way
intersection at 54th Avenue/53rd Street/C&E Trail
Cul-de-sac 53rd Street south of 54th Avenue to eliminate the 5-way intersection. The remaining four leg intersection should then be modified slightly so as to improve sight lines, though it would function as a four leg intersection from this point forward as illustrated as Option 4 on Exhibit 4-3B.
Intersection
Congestion on Woodland Drive at C&E Trail
While this intersection does not currently meet the warrant for signalization, it is certainly high on the priority list and should be monitored by the Town annually to determine when signalization should be implemented. The C&E Trail/Highway 12 and Woodland Drive/Wolf Creek/Highway 2A intersections are more in need of signalization and so the Woodland Drive/C&E Trail intersection would be the next in line after those intersections have been signalized. However, attention must be given to the warrants so as to avoid signalization without the necessary demand.
Closure of Maple Drive North of Rosedale: It is recommended that this road be left open until such time as the 63rd Avenue extension is in place, and even then opportunities for the roadway to remain open should be considered. Closure of this roadway prior to the development of the 63rd Avenue extension could increase daily traffic volumes in the school zone on 50th Street by as much as 25%. Although growth in traffic in front of the schools is inevitable over time, the opportunity to minimize that increase should be pursued. Keeping Maple Drive open will aid that cause.
51st
Avenue between Highway 2A and 53rd Street
This roadway provides parallel access to downtown
in relation to Highway 12 and should be protected as a Collector standard
roadway in order to optimize the viability of this function. Signalization at
Highway 2A will not be workable given the limited distance between Highway 12
and 51st Avenue. However, all turning movements here can be
accommodated in an unsignalized capacity so long as the intersection continues
to operate safely.
Reduction
of Truck Traffic on Highway 12
The Province should be approached to consider introducing signage on Highway 2 at SR 597 and at Highway 2A so as to encourage heavy vehicle traffic approaching from the south or north on Highway 2 that is destined for eastbound Highway 12 to utilize Highway 2A so as to avoid the Downtown core. It is noted that the Province may not be able to act on this request as they are not permitted (by legislation) to specifically encourage trucks to by-pass a section of Highway 12 in favour of Highway 2A.
Intersection
congestion and pedestrian safety at the 58th Street/56th Avenue
intersection
Analysis of existing conditions identified a pedestrian crossing issue here, though no data was available to assess the warrant for improved intersection management. It is recommended that the Town monitor the intersection, specifically collecting traffic and pedestrian volume data during the weekday AM, Noon and PM periods to assess the need for improvements to the intersection including the provision of improved pedestrian crossing accommodation.
