1. INTRODUCTION

The Central Lonsdale West Traffic Calming Plan was approved by City Council in May 2007. The primary objectives of the Traffic Calming Plan are:

• Safety — make neighbourhood streets safer for everyone, including pedestrians, cyclists, children and motorists.

• Livability — restore and enhance the livability of the neighbourhood.

The Central Lonsdale West neighbourhood is illustrated in Figure 1. It is bounded by Lonsdale Avenue, the Upper Levels Highway, Mosquito Creek Park, 13th Street and Keith Road.

1.1 Traffic Calming Plan

Key features of the Traffic Calming Plan include:

• Speed humps to discourage speeding on 17th, 19th, 20th and 21st Streets, and on Mahon and Forbes Avenues. In addition to discouraging speeding, speed humps also improve safety by reducing the frequency and severity of collisions.

• Speed tables to discourage speeding on 15th, 17th and 19th Streets, and on Bewicke Avenue. Speed tables are similar to speed humps, but are longer and are used on collector roads.

• Raised crosswalks on Jones and Bewicke Avenues, to improve pedestrian safety and discourage speeding.

• Traffic circles on Mahon Avenue at 14th, 16th and 18th Streets, to improve intersection safety, discourage speeding on east-west streets, and discourage shortcutting through the neighbourhood.

• Curb extensions on Chesterfield Avenue at 18th and 21st Streets to improve safety for schoolchildren and other pedestrians. Curb extensions were also constructed on Bewicke Avenue at 14th Street in conjunction with a nearby residential development.

• Driver feedback signs in two locations on 23rd Avenue, and at one location on Larson Road. Driver feedback signs incorporate a radar speed detector and an illuminated display to provide immediate feedback to approaching motorists, advising them of their speed relative to the posted speed limit. As of January 2010, only one of the two signs on 23rd Avenue has been installed.

• Crosswalks with flashing lights on 23rd Street at Larson Road and on Westview Drive at 19th Street to improve pedestrian safety.

1.2 Implementation

The majority of the traffic calming measures included in the Central Lonsdale West Traffic Calming Plan were implemented in summer and fall 2008, as summarized in Table 1.

Following the approval of the Traffic Calming Plan, the City determined that Jones Avenue should be reclassified from an arterial road to a collector road. This change meant that traffic calming measures such as raised crosswalks could be implemented on Jones Avenue.

Selected traffic calming measures were implemented on a temporary basis, so that their effectiveness could be assessed before constructing them permanently, and to provide an opportunity to adjust the design of these devices as necessary. Measures constructed to a temporary standard include traffic circles and curb extensions. As illustrated in Figure 2, these devices were constructed using flexile rubber curbing and temporary signage. Adjustments were made to the temporary traffic circles on Mahon Avenue in fall 2008 and spring 2009 to correct geometric issues.

Two of the three driver feedback signs were installed in May 2009. The signs stopped working in June and were repaired in July. The signs continued to work until October, when they stopped working again. As of January 2010, both signs are not working. Installation of the sign on eastbound West 23rd Street east of Westview Drive has been deferred until problems with the other two signs are resolved.

1.3 Post-Implementation Review

Now that a period of at least 12 months has passed since the majority of traffic calming measures were implemented, it is appropriate to review traffic data to determine the effects of the traffic calming measures, prior to implementing remaining measures and converting the traffic circles and curb extensions to permanent installations.

A Neighbourhood Transportation Committee — comprised of residents from throughout the Central Lonsdale West neighbourhood — was established to work with municipal staff in monitoring the effectiveness of the Traffic Calming Plan. Most of the members of the Committee were involved in the development of the Traffic Calming Plan in 2006/2007. The preliminary results of this post-implementation review were presented to Committee members in January 2010, and input and recommendations from Committee members have been incorporated into the findings and recommendations presented in this document.



2. ISSUES

Following the implementation of traffic calming measures in the Central Lonsdale West neighbourhood, residents reported a number of traffic-related issues, as documented in Table 2. It is important to note that some reported issues are beyond the scope of the Traffic Calming Plan, such as speed bumps in lanes (which are installed through the City’s local Area Services Program) and heavy trucks using Westview Drive(which is not a designated truck route).

Although most traffic calming measures have been well-received by residents, there has been significant controversy regarding the three traffic circles on Mahon Avenue, particularly the circle at West 18th Street. In addition to complaints received by telephone, email and letter, 28 residents (representing 16 dwelling units) submitted a petition to the City to remove the traffic circle at West 18th Street.



3. TRAFFIC PATTERNS

Following the implementation of traffic calming measures, the City collected traffic data at 49 locations in the Central Lonsdale West neighbourhood during spring and fall 2009, as indicted in Figure 3. Forty of these locations are the same locations where data were collected before the traffic calming measures were implemented, and nine are additional locations.

Figure 3 — Traffic Count Locations

Tables 3, 4, 5 and 6 provide a comparison of “before” and “after” traffic speeds and volumes. Speeds are recorded as “85th percentile” speeds, which is the standard measure of vehicle speed, representing the speed at which 85% of vehicles are travelling at or below (15% of vehicles are travelling faster than the 85th percentile speed). For the purposes of comparing “before” and “after” traffic speeds, changes of 10% or more are considered significant. For traffic volumes, changes of 15% or more are considered significant (changes of less than 15% typically reflect day-to-day fluctuations in traffic volumes).

Comparing the “before” and “after” data indicates that:

• Traffic speeds have declined by more than 10% in at least one direction in 23 locations. In all but one of the remaining locations, traffic speeds have remained within 10% of previous speeds. This indicates that overall, the Traffic Calming Plan has had the desired effect of discouraging speeding on neighbourhood streets.

• The only location where traffic speeds have increased more than 10% is the 400-block of West 15th Street, between Jones and Forbes Avenues. This increase in traffic speeds is undoubtedly a response to the speed tables installed to the east on West 15th Street. Although speed tables were installed in the blocks to the east to address speeding problems in these locations, they were not installed in the 400-block as speeding was not an issue at the time.



• Traffic speeds on Bewicke Avenue north of West 16th Street are 40 km/h northbound and 45 km/h southbound between 8:00 a.m. and 5:00 p.m. on weekdays when the 30 km/h school zone speed limit is in effect.

• Traffic speeds on Jones Avenue north of West 22nd Street are 42 km/h northbound and 45 km/h southbound between 8:00 a.m. and 5:00 p.m. on weekdays when the 30 km/h school zone speed limit is in effect.

• The driver feedback sign on Larson Road appears to have reduced traffic speeds. On northbound Larson Road at 20th Street where the sign is located, traffic speeds are 52 km/h, and north of 21st Street traffic speeds have been reduced 4 km/h to 59 km/h. Speeds remain above 50 km/h at both driver feedbacks signs (on Larson Road and on westbound West 23rd Street west of Chesterfield), however, which is particularly significant on northbound Larson Road where there is a 30 km/h school zone two blocks to the north.

• The installation of three traffic circles on Mahon Avenue south of 19th Street has resulted in an average reduction in traffic speeds of 18%. Traffic speeds have also decreased or remained within 10% of previous speeds on 14th, 16th and 18th Streets near Mahon Avenue.

• There has been a significant increase in traffic volumes on Mahon, Jones and Forbes Avenues between West 14th and West 15th Streets. A likely reason for this increase is the introduction of traffic signals on Chesterfield Avenue at 14th and 15th Streets, as these signals would make it easier for motorists to cross Chesterfield Avenue and travel through the neighbourhood to and from Keith Road. Traffic volumes may also have temporarily increased on Mahon, Jones and Forbes Avenues as a result of earlier construction at the Chesterfield Avenue/13th Street intersection.

• The increase in the volume of westbound traffic on West 17th Street east of Bewicke Avenue is due to the reconstruction of Westview Elementary School and the reconfiguration of access to the school.



4. ACTIONS

A comparison of traffic data before and after implementation of traffic calming measures as well as feedback from members of the Neighbourhood Transportation Committee indicates that the measures implemented to date have had the desired effects of improving safety and neighbourhood livability.

The only measures to have generated significant complaints are the three traffic circles on Mahon Avenue. The intent of the circles was to discourage speeding and shortcutting on Mahon Avenue and 14th, 16th and 18th Streets which might have otherwise occurred as a result of traffic calming measures installed on other neighbourhood streets. As expected, traffic speeds and volumes on these roads have decreased or remained the same. The only exception is an increase in westbound traffic on 14th Street east of Mahon Avenue, which is likely due to the new traffic signal on Chesterfield Avenue and construction at the Chesterfield Avenue/13th Street intersection.

Because the traffic circles have achieved the intended results, it is recommended that the City proceed to construct the three traffic circles on Mahon Avenue to a permanent condition. However, as noted in Section 2, a number of residents in the vicinity of the traffic circles have expressed concerns about all three circles, and have submitted a petition to the City to remove the traffic circle at 18th Street. Given this significant opposition, the City may wish to consider alternative traffic calming measures to achieve similar results as the traffic circles.

The most effective alternative to the three traffic circles on Mahon Avenue would be speed humps. Three speed humps could be installed on Mahon Avenue, and two speed humps each on 14th, 16th and 18th Streets, for a total of nine speed humps. These speed humps would achieve similar results as the traffic circles by discouraging speeding and shortcutting on Mahon Avenue and 14th, 16th and 18th Streets, without the issues associated with the existing circles.

Although the petition submitted to the City only asks to remove the traffic circle at 18th Street, residents have expressed similar concerns about the other two circles, and consequently it is recommended that if the traffic circle at 18th Street is removed, the other two circles be removed as well, to fully address residents' concerns.

If the circles are retained and are constructed to a permanent condition as recommended, prior to construction, the City should review the geometry of the each circle and make any adjustments to the temporary circles as appropriate. This will help to ensure that the geometry of the permanent circles is optimized and that the causes of many of the complaints from residents have been addressed.



Other actions which should be undertaken include:

• Install a speed table in the 500-block of West 15th Street, between Jones and Forbes Avenues. Traffic speeds in this section of West 15th Street increased after speed tables were installed in the blocks to the east, and the addition of a speed table in this block would discourage speeding along the length of West 15th Street.

• Construct an additional raised crosswalk on Jones Avenue at 22nd Street, to discourage speeding through the 30 km/h school zone and to improve safety for pedestrians crossing in this location.

• Construct the curb extensions on Chesterfield Avenue at 18th and 21st Streets to a permanent condition.

• Repair the driver feedback signs and install the third sign on West 23rd Street east of Westview Drive. While it was operational, the sign on Larson Road appears to have been effective in reducing traffic speeds (no data were collected prior to installing the sign on West 23rd Street west of Chesterfield Avenue, so it is not possible to determine the effect this sign has had on vehicle speeds).

Traffic speeds on some arterial and collector roads remain above the speed limit:

• Traffic speeds on Bewicke Avenue between West 16th Street and Larson Road exceed 30 km/h during the times the school zone speed limit is in effect. This is a common situation in school zones located on arterial and collector roads. Because Bewicke Avenue is a collector road, options for traffic calming are limited to raised crosswalks, speed tables and curb extensions. A raised crosswalk was installed on Bewicke Avenue at West 16th Street, improving pedestrian safety and reducing traffic speeds by 3 km/h southbound and 11 km/h northbound. It is unlikely that additional traffic calming measures would result in any additional speed reductions.

• Traffic speeds on Larson Road and West 23rd Street exceed 50 km/h by a substantial margin. These are both minor arterial roads, which means that options for traffic calming are limited to the driver feedback signs already included in the Traffic Calming Plan.

Other reported issues were not substantiated by observed traffic speeds or field observation, and therefore no action is required to respond to other reported issues.

The revised Traffic Calming Plan is illustrated in Figure 5. Actions indicated above are indicated in yellow, and are intended to be undertaken in 2010. These include an additional speed table on West 15th Street, permanent construction of the traffic circles and curb extensions, and repair and installation of all driver feedback signs.
