Byron-Tyndall-Gladstone Cycling Corridor Improvement Study
Update: The HCA received on July 3 along with other residents who submitted comments to the study an email from planner Wook Kang. he writes:
Dear participants of the above studies,
The attached are long over due summary of the public comments that we received regarding the Byron Avenue Area Traffic Management study and the Byron-Tyndall-Gladstone Corridor Cycling Improvement study, and our consolidated answers to the comments. There have been some changes in our recommended plan after we had the public meetings June-July of last year. The following is the summary of the changes:
If you have any questions or require further clarification please do not hesitate to contact me.
A copy of the HCA's comments one year ago to the consultation is at http://hintonburg.com/news.html#ByronFeedback.
The City is currently asking for comments related to significant new changes to the streets around Holland, Byron, Tyndall, Parkdale and Gladstone. It's hoped the changes will improve cyclist safety. Measures being contemplated include:
Note: City planners Wook Kang and Robin Bennett will be available at the Hintonburg Community Centre (1064 Wellington Street West) in the Laroche Room, July 3 from 7-8 PM to answer questions in an informal drop-in. Pick up a comment form or drop one off.
We've heard some good feedback already, and we'll spend some time putting together our comments to the City based on what we hear from residents. Please take some time to provide your feedback to the City by filling out the comment sheet available here and emailing it to email@example.com and copy firstname.lastname@example.org. Please consider copying us as well at email@example.com. The City will accept comments until July 20.
We've been provided with several documents by planners to help understand the changes. One of the most interesting is a proposal to build "mini-roundabouts" at Hamilton and Hinton at Tyndall. Planners have given us the following information about them:
The planners provided us with photos of a "mini-roundabout" in Burlington ON, the only other city in the province to have them currently. If employed as part of the Tyndall plan, they would be the first use in Ottawa. Right click and open any of these in a new tab to view them full size. Detailed plans for the Hinton and Hamilton roundabouts are here and here.
The mini-roundabouts, according to planners, may or may not assist with cycling safety. However, they will likely slow traffic on Tyndall with safety benefits. Planners tell the HCA that 85% of traffic (the metric to which planners pay the most attention) traveled at 48 km/h or lower in 2012. In 2006, this was slightly higher: 50 km/h (view the 2012 speed study here).
According to studies, collisions with pedestrians at 50 km/h is likely to result in a fatal injury around 85% of the time. This probability decreases to around 10% at 30 km/h (right click and view the image in a new tab for more info). It is expected that traffic on Tyndall will be reduced to 25 km/h around the roundabouts, with higher speeds in between.
In our preliminary conversations with planners, it's becoming clear that the mini-roundabouts are primarily a traffic-calming measure, rather than a cycling measure. This may or may not be a reason to recommend either for its implementation or not. It could be considered a "nice-to-have" or even important to have if traffic speed on Tyndall is a concern. There is budget attached to the proposal and it has pre-approval as part of the 1997 transportation study. However, residents may also wish to consider whether the expense and inconvenience to pedestrians resulting from the re-alignment offset the benefits.
The HCA is arranging a small, informal meeting with planners so that residents can ask further questions, including about the experience of mini-roundabouts in Burlington. The date and time of that meeting will be announced soon.
