We’ve found an intersection in Dublin’s city centre that appears to be particularly dangerous for cyclists. And we have some ideas on how to improve it.
On 20 October, we posted a map designed to crowd-source information on bicycle collisions and near-collisions that might otherwise have gone unreported. Our hope was to identify problem areas and bring attention to them.
Since then, there have been 139 submissions to the Dublin Inquirer Bicycle Collision Tracker map.
Patterns appear to be emerging. There is a discernible cluster of reported incidents in the city centre, and it’s only a stone’s throw from Dublin City Council’s Civic Offices at Wood Quay.
Two accidents have been reported at the intersection of Bridge Street and Cook Street, and three more just south of the intersection on Bridge Street Upper before it meets High Street.
We caught up with one of the respondents and talked with him about his near-collision on Bridge Street Upper, just south of its junction with Cook Street.
“I basically got squeezed off the road,” says cyclist Cormac Farrell. “I don’t know if I actually got hit, but I definitely felt the wind and had to jump onto the footpath and drag my bike out of the way.”
Farrell says he cycles the route routinely and never feels safe going up the steep hill alongside St Audoen’s Park.
“I just find that motorists are generally quite aggressive there because they’ve been stuck trying to get over the river,” says Farrell.
“I drive a car as well, so I know what it’s like trying to get across the quays,” he explains, saying it’s “a complete nightmare”. Once on the other side, “you kind of get onto that wide bit of road and just go for it, especially if there’s a green light up ahead.”
The problem is, there is no cycle lane on Bridge Street.
What makes matters worse, explains Farrell, is that the street gets narrower as it winds up the hill beside the park. “It’s like a funnel, basically, and there’s nowhere for a cyclist to go.”
We visited the intersection in question with Colm Ryder of the Dublin Cycling Campaign, to get his take on what makes it such a dangerous area for cyclists.
“There are absolutely zilch – no facilities whatsoever for people cycling,” says Ryder, who points out that it is the same for walking. Only one of the intersection’s four pedestrian crossings is signalised to help provide those on foot safe passage.
“There’s no filter for the right-turners, so they’re always trying to break in to get across traffic,” says Ryder of traffic turning off of Lower Bridge Street, onto Cook Street.
Traffic was at a crawl approaching the quays when we spoke.
Ryder said that when traffic moving north towards the quays on Bridge Street is at a standstill, southbound cars turning right onto Wormwood Gate may not see a cyclist coming down the hill, and might make the turn.
If a cyclist isn’t wise to the danger, she or he could ride straight into trouble.
Says Farrell: “I’m always wary of that intersection, that cars coming against me are turning right across my lane. They will always be going and taking a chance there.”
As far as Ryder is concerned, the junction is an example of bad design.
“It’s a huge expanse of roadway with no break in the middle. The junction is just a disaster, it needs to be totally redesigned. Look at the curves!” says Ryder, exasperated, as he points to the obtuse street corner we are standing on. “It’s not pedestrian-friendly, it’s not cycle-friendly.”
Grab Your DMURS
It’s not just cycle advocates who would say this intersection and its surroundings are inadequate. If you flip to page 104 of Ireland’s own Design Manual for Urban Roads and Streets (DMURS) and look under the “Junction Design” heading, you will see there is a lot of work to do.
The first design principle simply states, “provide crossing on all arms of a junction”. With only one crossing out of four arms provided for at this particular junction, we are not off to a good start.
How sharp or gentle the curve of a street corner is influences how fast cars travel around it according to DMURS. As Ryder indicated, the corners of this particular intersection are quite gentle and allow cars to take the turn really fast.
The next key design principle for traffic junctions, according to DMURS, is to “reduce kerb radii”, which is a fancy way of saying replace that gentle curve with a sharp corner. Doing so not only slows turning vehicles, but reduces crossing distances for pedestrians and makes it easier for drivers, cyclists and pedestrians to see each other.
The sketch below illustrates how corner radii can affect a junction’s safety.
The next design principle has to do with omitting left turn slips, which DMURS describes as “highly disruptive for pedestrians and cyclists”, without adding much vehicle capacity. Our junction has a left-turn slip from Cook Street onto Bridge Street Upper, just before the spot where Farrell was run off the road.
It looks like Ryder’s description of this junction as a disaster is backed up by DMURS, but where do we go from here?
Not the Only One
As the Cycling Campaign’s Ryder sees it, the junction at Bridge Street and Cook Street is one of the many junctions in the city centre that are dangerous for cyclists and pedestrians.
Many of these problem junctions are a legacy of a time when road design was aimed at maximising throughput of motor vehicles at the expense of pedestrian and cyclist safety.
“The obvious thing to do here is to have a decent cycle track with a single wide carriageway in both directions,” says Ryder.
Farrell agrees with the cycle lane bit, but thinks you could shave off a bit of footpath on Bridge Street to create it. “The footpath is quite wide,” he says, “it could possibly accommodate a cycle path.”
“My general opinion is to not hug the hill,” advises Farrell. “If you allow cars to think that two of them are going to squeeze past you, they will. I would say the best thing for a vulnerable cyclist to do is to command the road and don’t let drivers take the chance of passing you and squeezing you off the road.”
Although he is critical of this intersection, Ryder is far from a cynic when it comes to Dublin City Council.
“They [city council] want the city to be a better city,” he says, adding that council officials have made it clear to the Cycling Campaign that better infrastructure for pedestrians and cyclists is high on their agenda.
“Literally, as we speak, there are interviews for a new cycling [and walking] officer at Dublin City Council,” says Ryder. “The new cycle officer will be pushing the case internally; I think that will make a big difference.”
