Vehicular Cycling (VC) - What if?

Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.

What if the roads were built as though the default vehicle was a bicycle?

Same as it ever was. Except perhaps a substandard lane would be any lane less than 7' instead of 11'
Oh, and road sweepers would be more common.
Al
dedicated lanes with separate lights? I always liked the looks of thos bike lanes in the middle of the street with trees on either side in places like Bogota, yes, more frequent sweeping. lower speed limits.

No I mean, what if the default vehicle that roads were designed for was the bicycle?
Everybody says the roads we have are fine. But I think that they are designed too much around a single type of use. Got me thinking, what if the default use they designed them around was bicycling? How would people who drive have to adapt? They'd probably be the ones cowering at the side of the road, don't you think? I'll betcha there'd be lots less 4-way stops and a lot more roundabouts. Drivers would have to figure out how to take the lane -- or take two lanes in their case -- without being yelled at. Things would be different.

If roads were built at bicycle scale, many roads (assuming single bike-size lane in each direction) wouldn't even be useable by larger motor vehicles without causing opposing bike traffic to have to pull off the roadway. Motor vehicle traffic would be in a real bad situation. If roads were only built to withstand the weight of cyclists but saw motor vehicle use too, we'd all be riding full suspension mountain bikes in a few weeks.

You would probably starve to death through inability to deliver food and other necessities.

Really... they manage to deliver food just fine using very narrow vehicles in places like the Latin Quarter in Paris France, where no regular car will fit.
As an aside I did happen to hear of one place where there is no motor traffic... North Korea. The pronoucement of this situation came from a UN visitor just the other day on NPR. No traffic... if that was what you really desired.
Here is a travelogue by someone else on a trip to NK outlining the same situation:

What if the roads were built as though the default vehicle was a bicycle?
Go take a look at the road system on Okinawa. I think it would be about like that. Granted their roads, particularly in residential areas, are built with cars in mind, but a lot of them are teeny-tiny cars, not much bigger than a Amercan golfcart.
Imagine residential roads that are not only one lane, but a narrow single lane.

What if roads were built for bicycles? Depends on who builds them!
If it were me, they would look fairly much like our current streets and highways, with the following differences:
– Lanes would be 1,5 to 2.0 m wide (5-6.5 ft), with good passing opportunities.
– More protection from the elements: trees not only enhance the scenery, but they protect from headwinds.
– There would be one or two car lanes per direction with 3,5-3,75 m (10-12 ft) lanes for trucks, cars that need to be there, etc. Basically cars and trucks would be required to use the expressways, except for the local portion of their trip (a bit like trucks usually have to do in many jurisdictions), so there would not be a flood of cars everywhere.
– There would not be situations with "right lane must turn right", freeway-style entrances and exits.
– Traffic lights are necessary and so are stops, but they would be required much less frequently.
– Route configuration depends on topography, but generally there would be more curves and less hills. Curves would have a reasonable radius so a tandem bicycle with trailer would easily negociate them at 30-35 km/h (faster downhill).
And the last ones (humour on...):
– Have motor vehicles stop each time they have to cross a bicycle lane. Even if they could merge safely otherwise. And at intersections, motor vehicles would arrive at an odd angle and have to stop for bicycles and pedestrians in all directions.
- Why not put bollards where motor-vehicle lanes cross the bicycle lanes. Car drivers would have to stop, remove the bollard, cross the intersection and re-install it afterwards. 200 $ fine.
– For difficult intersections, maybe we should ask people to stop their engine and push their motor vehicle through the intersection. Ditto for narrow passages.
Now if they were designed for bicycles by our current (motor)-transportation engineers, they would have:
– lots of tight curves – especially useless ones – with poor visibility, trees or lightposts in the way, etc.
– bollards everywhere, painted black so they are more effective (i.e. more roadkill).

About the same as they are currently. I can't think of any aspect of the paving of roads which would need adjustment if bicycles were the default. Assuming there were any cars at all the widths to accommodate
cars would be necessary. And modern road surfaces are very kind to cycling.

I always thought that cars should be designed to be wide enough for a single person, with passengers behind the driver. Then we could have more lanes simply by making them narrower. If all the lanes were narrow, it would be easier for a bicycle to control a whole lane.
I think the balance of "power" would be more equal between motorcycles, bicycles and cars, too, since they'd be roughly the same width. Plus with so many lanes, they'd understand how to change lanes to pass a bicycle. Since most cars usually carry only a single passenger anyway, they should probably be that size.
So then the roads would have skinny lanes. You could have tiny roads in residential areas with wide green spaces for kids to play or people to landscape nicely. You'd have way more parking available at shopping centers, or less parking lots.
Maybe people wouldn't be so fat, too. I mean, you buy bigger pants and that gives you a license to overeat until you have to buy bigger pants next time. Seems to work the same for cars. Buy a bigger car and start shopping at the warehouse stores buying vats and cases of food. Even in my town full of skinny perfect people, just stand outside the big-box store and see how huge the people who shop there are. Then take a look at the size of the SUV they're putting all that junk into. Some seem to be outgrowing their SUVs, just like their pants.
Yep, I guess ol' JF is spinning in his, well he's not dead yet, but I'm sure he's foaming at the mouth at my obvious hatred of Amer'ca. I just think that saying the roads are just fine the way they are means you never gave any thought to how much they've been shaped to serve only one mode of transport. So if they were designed for another mode, how would the others have to learn to cope? As useful as vehicular cycling is, it really is a form of coping with a system not designed for us.

Speeds would be slower and the air would actually have a wonderful fragrance to it much of the time.
I'd probably still seek out alternate afternoon routes away from the bicycle traffic jams. :)
There would be businesses built around cycling, just like they are around motoring. Not just bike shops as we know them, but food and rest stops tailored to small trips, hotels, hostels, and B&B's centered around longer trips, more and better accomodation on transit such as air and rail, bike parking everywhere, huge bike accessory businesses, lots of bicycle racing and competetion, etc.

Hold on, I thought this exercise was just designing roads with bikes as the default vehicle. That doesn't mean that bikes are going to be any more popular. Do you think that just because road designers mainly have bikes on their mind will change the fact that the human species has evolved to be as lazy as possible (much like any other species)?

I think/hope one thing that would happen is, similar to lanes where folks swim laps in the pool, the faster riders would get in one lane, probably the one on the left; and slower riders would be successively further to the right. Then the fast cyclists could yell at the slow cyclists get the hell off the road! :)

Of course, building roads with bicycles as the default vehicle would not make cycling suddenly more popular.

Roads are currently designed based on the speed limit - from sight lines, to signage, to grade and sharpness of turns. A system designed for bikes would be based on vehicles traveling no faster than 40km/hour (at least, that is the standard proposed locally). That means the roads would be difficult, if not impossible, to use at high speeds, effectively forcing motor vehicles to slow down.
A system designed primarily for bikes would also see less regional separation, more bridges/links at natural barriers (e.g. rivers), and fewer long detours around obstacles. Overall the system would also be more pedestrian-friendly.
Since the system would take far less surface area, main transportation corridors could be at least 50% more narrow, and we could eliminate 75% of parking lots. This space could be re-claimed as green-space, and/or zoned for mixed-use development - thus making more efficient use of municipal services and countering urban sprawl.

I honestly have to question that... While one would think those factors are evaluated... how does that explain increasing the speed of a road without modifying any of the above factors.
How does road design explain 55MPH speed limits on narrow coast hiways with hairpin turns?

Good thinking. As a minor adustment I'd hope in this fantasy world that primary (bike highway/arterial) roads would be designed for 30mph (~50kph) instead and even higher speeds for downhills.

Irresponsible design? Politically motivated changes?
I don't claim to speak internationally (unlike many people online :mad: ) all I can say is that here roads ARE built to a specific speed standard, and I don't recall the speed limits ever being increased on any local or regional road.

I'd assume such a system would have a range of design speeds, depending on the road type, but I think 40km/hr is more likely than 100. (40 km/hr is our design standard for MUPs, BTW.)
While I don't think a shift to a system designed primarily for bikes is likely, I do think a shift away from car-centric design is, in fact I see it happening now in subtle ways. Right now I see it more as mindset than physical reality - every study or proposal for local road construction now explicitly considers cycling and walking, as well as HOV and transit lanes. Ditto all "official plans". Clearly our engineers, elected officials, and consultants no longer consider it socially acceptable to do otherwise. Consideration does not always translate to the final plans, but it is a step in the right direction.
I am also seeing a great deal of opposition to road-widening projects. People, particularly in high density areas, are starting to object to losing yet more space to roadways. Again this is only a first step - they don't want more roads, but have not yet bought into the idea of cutting back on road use. One step at a time, though.

Hmmm you mean you guys up in the great white north actually plan these things?
Down here in the states... especially in the crazy state of California, they build the roads and then wait to see how fast people drive, and then tack on a sign. Doesn't matter how safe the drivers are, or what the sightlines are... what matters is that no one gets in the way of the almighty auto. There are actually provisions to modify the speed based on what 85% of the motorists are doing... so if the motorists choose to go bumper to bumper at 55 MPH... hey, that's the road speed. (not quite as simple as that... but the results do tend to end up that strange)
The funny (sad ironic) thing is that if you put most folks in a car with windows rolled up and air conditioned with power steering and power brakes... they have a tendency to be disconnected from the actual driving environment and over drive (drive beyond the sight lines). But hey, no matter... roads are for cars, right? :rolleyes:
Sports car owners?:p
I don't think even sports cars can do those hairpins at 55MPH... though no doubt, some try. You usually hear about them in the evening news... "Motorist loses control on hiway... news at 11."
Does anybody come back and say... gee, ya think the speed limit is set too high on that road? Naaaaa.
Locally I have two roads that are surface streets with speed limits at 60 and 65 MPH respectively... they both parallel freeways... (within a 1/4 mile) with speed limits set at 65MPH. So why is a surface street, with driveways, and intersections set at the same speed as a freeway? And if I can ride a bike on those surface streets (which both have BL) why can't I ride a bike on a freeway? Many other arterial roads have speed limits set at 50MPH. (as if motorists only went 50... )
Yeah... common sense kinda goes out the window there, eh?

Oh yeah, we plan. We're great at planning. We have a taskforce to propose a plan to create a committee to create a plan. Then we do public consultations to plan changes to the plan, and commission environmental assessments on the plan, and compare the plan to other plans. Its all very well planned out. And once all this planning is over, we look at each other helplessly wondering what happened to all the money set aside for the project.

I think that overall, it would be a negative outcome. Cars, trucks, and so on, are good at a lot of things. Moreover, cycling isn't the easiest activity for a lot of individuals. Just consider the elderly, the young, and the infirm. Nor is it the optimal mode of transportation for many circumstances/activities.

And how many of us would want to live in North Korea? Maybe some of you bicycle advocates should move there? As some others of us have commented, either love this nation or leave it.
As for the Parisian area mentioned above, just what is the length of the trips made by these vehicles that are narrower than cars, and from what mode do these vehicles acquire their loads? As the American truckers say, if there's food in your grocery store, it is there because a truck brought it. I find that one reason that the anti-motorists advance silly arguments is that they fail to understand the utility of motor transportation. And, of course, to suit their ideology, if I mention it I am an evil motoring advocate. There are those on this list who insist that I start to understand modern thought; it appears to me that I am the one who does, while they are stuck back in the streetcar era.

By "this nation" I assume you mean the USA, right? You might want to have a look around this web site some day, it may be US dominated but it is bikeforums.NET and not bikeforums.US - and does have an international membership. You might also want to take a good hard look at your "love it or leave it" attitude, aka "with me or against me". That attitude is a large part of why you find so much opposition to you and your ideas.
