Some remarks on the report to be presented to the Standing Committee on Planning, Transportation and Environment [2], On July 22.

Bus stop and line of sight at Burrard#Pacific

As mentioned in a previous post’s comment, the COV planners indicated some line of sight involved by the Burrard street concave alignment at Pacific were cause of concern for CMBC toward the implementation of a South Bound bus stop on the South West corner of the intersection. The problem is illustrated below:

due to the concave alignment of Burrard. A bus could need to be positioned at an angle preserving line of sight on incoming traffic, before reentering traffic: that would be an angle similar to the current slip-in lane to  not compromise lines of sight

Hindered lines of sight for bus leaving a stop, due to a concave alignment of the street, exist in multiple locations on the Transit bus network. a short list below:

While the line of sight concern are legitimate, they could have been overblown in the case of Burrard bridge. They can be addressed by external safety mirror, as often seen in Europe. Here there is sufficient room to accommodate an articulated bus at an angle preserving the line of sight for a safe pull-out:

A design, where the bus bay is in the alignement of Burrard street North of Pacific [4], bus bay designed in accordance with [3]. The tall cypress is obviously not in the way. A protected bike box with an advanced traffic signal allow EW connection along Pacific

We were admittedly too optimistic to see the City elaborates on the above solution. Instead, The line of sight concerns expressed at the open house, have since been replaced by the concerns on the preservation of a cypress tree which could not have been endangered by a bus bay on the south side.

We tend to see all that as excuses for inaction. Whether not, the restoration of the south bound bus stop on the North West corner of the intersection should have been in order. However, after feedback of the public, the initial proposal to move the South Bound bus stop further north has been given up. Instead, the bus stop will be moved south by half a block (from Burnaby to Drake). It is a step in the right direction, but insufficient: It seems nothing more than paying lip service: Transit accessibility is still much worse than it was in 2009 and before.

Pacifc East West bike connection

Our above proposal integrate them with an island to create a protected bike box, which can be given and advanced signal. the design to be submitted to the council also propose a bike box, but in what seems to be a more clumsy way:

the bike box for thru movement is in a right turn bay! this right turn bay is supposed to have green light while the the thru lane could still be on red (to protect right urning from Burarrd to Pacific East). That creates confusion and place cyclists in an uncomfortable spot

The Suicide prevention barrier

This part was not presented at the open-house, and “popped up” afterward, the reasons why are unclear, since the City is supposed to have engaged with stack-holders ahead of the general public open-houses, where the issue could have been identified. Burrard bridge being such a iconic bridge, its alteration by suicide barriers, which also hinder the view of the bridge span, and affect negatively the user experience, raise some legitimate concerns from heritage groups.

Mapo Bridge, Seoul, Korea, use technology, art and interactivity to reduce suicide rate, without relying on high suicide barrier

Due to this, the request for more consultation seems reasonable. The city could explore alternative to physical barriers. The Mapo bridge in Seoul, Korea, using technology to detect suicide attempt, and then connect victim with help, could be an option to consider, after having a correct assessment of the experience [1]

Overall, The Burrard North end project seems to be a bit rushed.


[1] Many medias, especially in North America, have reported the experience as failure, because the reported “suicide attempt” have increased by a 600% after the introduction of suicide prevention measure. However many observers consider the experience as successful, since the effective number of committed suicide has been reduced by 77% . One can conjecture that distressed people could target Mapo bridge, knowing they get a chance to be recognized as such and get helped. On the Authority side, it also help to locate those distressed people, and provide them with the needed help to prevent suicide in general.

[3] BC Transit Infrastructure Design Guidelines, Nov 2010.

[4] here we provide a design maximizing the line of sight. However, the required length of the line of sight could be shorter, allowing to reduce the angle of the bus bay.

On June 1st, The city of Vancouver released its plan to upgrade the intersection at the North side of the Burrard bridge [3]:

The revamped interestion feature a Bike lane on the East side of the Burrard bridge, granting access to pedestrian on the east side too, and the removal of the accident prone slip lane

Beside the removal of the accident prone slip lanes, and the reopening to pedestrians of the East side of the bridge deck; granted by a new bike lane; there is little improvement for the cyclists and pedestrians: Many connectivity options are still forbidden, either by law or by design:

In red, the prohibited directional change for cyclists (see bottom of the post for the bus stop suggestion)

Notice that the design allows to do a left hook turn from Burard Northbound, or Pacific Westbound since the intersection presents a Dutch interesection characteristic on its North side

  • Same could be possible on the South side, albeit at the price to add a traffic signal cycle, to allow unimpeded bike/pedestrian East-West movement on the South side of Pacific. (but what are the priority of the city?)
  • Alternately, the construction of ramps to allow to use the bridge underpass (lane on the south side of Pacific), could provide a solution if such is possible

Worth also to note that the planters separating the bike lane on Burrard Street would be gone:

  • Such planters are insulating the bike path too much of its environment, what create a safety hazard at interesection
  • That said such a wrong step seems to be taken on Pacific

All in all, due to the non addressing of prohibited turns for active travel mode, the proposal looks more as a missed opportunity to improve connectivity for cyclists and pedestrians than a real improvment: in some sort, the whole exercise seems more guided by the ideological desire to remove a lane of traffic on the Burrrad bridge than anything else.

All that could be not that bad if the proposal was not used as a weapon to attack the city buses once again.

The Transit issue

bike lane in Vancouver are typically built at the expense of anyone not cycling

When the West side bike lane has been built in 2009, the southbound bus stop at Pacific#Burrard has been decommissioned: another bus stop has been implemented at Burnaby#Burrard. Especially due to the steep terrain nature in the vicinity [1], that has defacto put the south side of Pacific street out of reach of the Burrard buses, hence the Frequent Transit network, while he Burnaby bus stop is widely redundant with the Davie bus stop in term of coverage:

400m Catchement area  of  bus stop considering the street grid and terrain elevation change: in green the Davie bus stop coverage. In red, the additional area covered by the Burnaby bus stop. In blue the area not covered any more due to the lost of the Pacific bus stop Southbound.

Far to improve this dire situation, it is suggested to make it worse, by relocating the Burnaby bus stop ever farther away: the new Burnaby bus stop could be a mere 30 meter away of the Davie bus stop!

Why that?

Because the city so far has conceived its bike lane at the expense of Transit. The “legacy” bike lane on most of Burrard looks like below:

The existing bike lane on Burard is sandwiched between general traffic lanes and a bus lane: a less than ideal situation credit photo (2)

An obviously less than ideal pattern, which call for correction: a protected bike lane. That is good, but on the city watch, it is apparently not compatible with a bus stop. Of course it doesn’t need to be…even in Vancouver:

Several ways to address the bike+bus interaction exist, as noticed by Jarret Walker. As him, we prefer a “table” or shared space solutions for the bike lane that alert the cyclist to yield to peds in this situation, as we have seen before:

An example of bike + bus stop inetgration

It looks the city is more leaning toward a floating island concept, which is at least considered for the Burrard#Pacific Northbound bus stop: the important is to see the access to transit to be addressed. What is possible for the North bound bus stops, must certainly be too for the South bound bus stops

In the present case, it looks like the removal of the slip lanes allow for ample room at the south-West intersection to implement a floating island concept with a bus bay (to not impediment traffic) as suggested in the second illustration of this post.

In any case, the lack of connectivity improvement for cyclists and more critically, the absence of consideration for transit, make the city proposal a bad one. On a positive note, those shortcomings are relatively easy to address and we are hopeful to see the proposal modified in a postive direction


[1] a rule of thumb is to consider that 10 meters elevation change is equivalent, be in time or energy, to 100 meters distance on flat (e.g. the Grouse Grind hike is 2.8km long but with an elevation change of 853meter: that is equivalent to a hike of 11.43km (2.9km+ 10*0.853km) on a flat terrain.
