Robson Square vs. The Robson 5: Fruitful Debate or False Dichotomy?



Vancouver's planning circles and concerned citizens have been abuzz with news over the proposed reopening of Robson Street between Howe and Hornby to automobiles and buses. Peter Marriott has done a fantastic series of articles on Gordon Price's blog on the importance of leaving Robson Street open to the #5 Robson route. In short, the main problem with the Robson Street closure was that because of detours, the #5 Robson lost crucial connectivity with the rest of the city west of Robson Square.

So since Peter's done all the work of explaining the reasons, I'd just like to tack on a couple of my own observations:

1. Normally I visit the West End every now and then, 

to get delicious, delicious ramen at Kintaro or Santouka (Denman @ Robson). Since the rerouting of the #5, I haven't visited the West End at all, because it now takes about 10 extra minutes to get there (at least when coming from areas south of FC). While that might not seem like a whole lot of time, I would imagine it would quickly add up for a resident of the West End: an extra 20 minutes a day is an extra 100 minutes of commuting a week. The 5 Robson also happens to be a particularly high ridership line, so the aggregate amount of time wasted is substantial.

2. The grounds for a transit vs. pedestrian debate are tenuous. 

Examples from around the world show that it IS possible to have transit and pedestrians in the same space. What's more, it's also possible to have buses and pedestrians in the same public space. Andrew Jones demonstrates some excellent examples of light rail and streetcars that cruise through public spaces. Here are a couple of public squares where buses are allowed or given exclusive access:

The Baldachin (great glass roof) in Bern, Switzerland, houses a public square and combination bus/light rail interchange. The S-bahn/intercity train station is located underneath, so there is always tons of activity and movement, even though the city of Bern itself isn't even half as populous as Vancouver. (pop: 125 000)

And my favourite is a little plaza in Paris you've probably never heard of (yes, I did just say that!). I'm not even sure if it has a name. Tucked immediately beside St.-Paul station on Ligne 1 is a trapezoidal sliver that works perfectly in its role as a public space: a narrow, slanting public square to mimic the narrow, crooked streets of Le Marais. Even though it's tiny, only buses and delivery trucks are allowed though. Other vehicles need to reroute.

Buses move slowly through the square, but it's a lot faster than making the long detour:
but no cars allowed through! (c) Google Street View

Metro riders spill out into the space and create a lively atmosphere whenever the time, whatever the season. The bus exclusive lane is on the left; Rue de Rivoli is on the right. There's even room for a carousel (the covered yurt in the back):

Just a few examples of some of the creative planning that's been done around the world to accommodate public spaces and effective transit.

4th and King (Caltrain Railyards) Proposal

As part of an urban design studio at Stanford (URBANST171), I created an urban development plan for the Caltrain Railyards that currently sit South of downtown San Francisco. Future plans call for I-280 to be converted into a ground-level boulevard at 24th St. in Potrero Hill and Caltrain to be buried underground in the same tunnel as California High Speed Rail, leaving an enormous plot of land available for development. Caltrain hopes to move the 22nd st. station to the intersection of 16th st. and 7th, and bury the station at 4th and King underground, along with the possible High Speed Rail station too. HSR and Caltrain would then continue up to the Transbay Terminal just off of Market St.

As part of my proposal I concentrated on the transportation connectivity of the site to the rest of SF, something that has been lacking in recent years. 

Some more images from the proposal:


Here's the entire presentation, somewhat successfully imported into Prezi. Contact me if you'd like the original ppt, which is a bit more coordinated in terms of fonts and color schemes.

First Post!

Welcome to my academic/professional blog on urbanism! My full name is Theodore Lim, but you can call me Theo. I grew up in the beautiful city of Vancouver, Canada (which will forever be my home), but for the past 2.5 years I’ve been studying Civil Engineering at Stanford University in California. At the current moment I am abroad in Paris, France, but I’ll be back on campus in April 2012.


I’ll start this off with an analysis of the interesting street life just in front of my building. Here's a view out my window: the facade across the building is the RER Line B stop Cité Universitare. In the middle of the street is the tramway (Line T3) stop of the same name. In spite of the fact that there is virtually no commercial life directly near the station, this place is always filled with people, most of whom are transferring from the N-S RER line to the E-W Tramway line.



Cité Universitaire is along the southern side of the city and is a quarter dedicated exclusively to student housing. Look for the RER line B (thick vertical blue line); trace it from the bottom of the map till it intersects with the thin orange line in the bottom quarter of the map.  The Cité consists of over 30 maisons representing different parts of France and different countries around the world. However, there is basically no commercial activity in the area, except for the cafeteria, bakery, and theatre in the Cité Internationale main building, located about 100 m south of the Tramway stop. North of the stop is Parc Montsouris, a large park which is popular with joggers and families which has a gentle slope upward toward the station.
Most of the pedestrians who use Cité Universitaire transfer to the Tramway from the RER or Vice Versa. The RER itself is actually much faster than the Métro, as it has fewer stops and runs with higher speed trains. Such is the case that people will take the tramway from Jean Moulin or Porte De Choisy to Cité Universitaire to take the RER because it’s that much of a time saver.
Because of the high numbers of rushed pedestrians, it’s interesting to see what the planners have done with the intersection.




Point 1: Placement of traffic lights
Now this is actually something seen all over Paris. The traffic lights here are not strung up high over the traffic; no, all the traffic lights sit about 3 m (10 ft) above the ground directly on lampposts. There’s also a mini traffic light lower down on the post, which specifically caters to the first motorist in the lineup (who can’t see the traffic light above) as well as to any bicyclists. This entire traffic light setup is meant to keep motorists looking down at the road ahead, where people are likely crossing.
Point 2: Distribution of Traffic Lights
Notice that there are not just one set of traffic lights in front, but actually two more sets down the road. About every 30 seconds, or whenever a tram arrives, all the lights turn red at once. Any cars stuck in the ‘middle’ of the intersection are forced to stop instead of carrying on their way. In this way, traffic on the entire street stops, allowing pedestrians to cross. It doesn’t matter if there are cars in the way because pedestrians can easily thread their way through the breaks. What’s important is that all traffic has stopped, and then the entire length of street from the first traffic light to past the last traffic light essentially becomes one long pedestrian crosswalk.
Point 3: Textured Driving Surface
Not only at the crosswalk, but also about 20 m before and 20 m after, there is a cobblestone texture on the road instead of asphalt. Essentially this indicates that ‘there might be pedestrians crossing here anyway’ and, in a sense, appropriates the right-of-way to the pedestrian. There’s something subconscious and powerful about the rumble of driving over cobblestone streets that tells drivers to slow down and cede pedestrians the right of way.



Point 4: The Grassy Median
Pedestrians (such as myself) will often cross using the grassy median. This is generally not a problem or a hazard to the trams, since they tend to run at slower speeds and can stop about as fast as a car can. (Still, you need to be extra careful when crossing any set of train tracks!) Instead of fencing off the tracks, filling in the tracks with grass is not only pretty, but allows the pedestrian more freedom to cross the street at will and breaks down the barrier usually created by train tracks.
Point 5: Bicycle Signalling
The bicycle lane merges with the road near the station as the rights of way are not wide enough and a bicycle lane cutting through the pedestrian crosswalk could be dangerous. So instead, the bicyclist is asked to merge with traffic, taking advantage of the frequent red light cycle to give the cyclists priority to merge without being afraid of getting sideswiped. See in the first picture that the bicycle light (middle right) is red while the auto light is green; when the auto light is red, then the bike light turns green so that cyclists can merge into the road without problems. The cyclists are asked to stop with the auto traffic to give pedestrians the right of way; although cyclists often just continue through without stopping, the merge with auto traffic causes them to slow down and be more careful when crossing through the pedestrian crosswalk.
Point 6: It’s intuitive
The best part is that the entire intersection is intuitive. Each person or user of transport is given only one thing to watch for, or one area to watch at a time. The drivers watch the lights, which are positioned low down to make pedestrians visible. The pedestrians watch for cars at the road, then after the island, they are warned by large tram crossing lights if a tram is coming (or one could just look down the tracks - there are no obstructions). Bicyclists don’t have to worry about getting clipped, so they can themselves prevent collisions with pedestrians.
And… that’s about all I’ve got to say about design. The intersection works - well, I might add.
