Traffic management: APPlied logic
un sujet a posté mtlurb dans Urbanisme, architecture et technologies urbaines
Traffic management APPlied logic Sep 13th 2011, 16:10 by The Economist online TRAFFIC lights are crucial tools for regulating traffic flow. They are not, however, perfect. Drivers exchange the gridlock that would happen at unmanaged junctions for a pattern of stop-go movement that can still be frustrating, and which burns more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle’s speed so that it always arrives at the lights when they are green. That is theoretically possible, but practically hard. Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a junction, but such signs are expensive, and have not been widely deployed. Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachussets Institute of Technology, however, have an idea that could make the process cheaper and more effective. Instead of a hardwired network of signs, they propose to use mobile-phone apps. For a driver to benefit, he must load the team’s software, dubbed SignalGuru, into his phone and then mount it on a special bracket attached to the inside of his car’s windscreen, with the camera lens pointing forwards. SignalGuru is designed to detect traffic lights and track their status as red, amber or green. It broadcasts this information to other phones in the area that are fitted with the same software, and—if there are enough of them—the phones thus each know the status of most of the lights around town. Using this information, SignalGuru is able to calculate the traffic-light schedule for the region and suggest the speed at which a driver should travel in order to avoid running into red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities. This was particularly impressive because in Cambridge the lights shifted, roughly half-way through the test, from their off-peak schedule to their afternoon-traffic schedule, while in Singapore lights are adaptive, using detectors embedded under the road to determine how much traffic is around and thus when a signal should change. In neither case was SignalGuru fooled. Fuel consumption fell, too—by about 20%. SignalGuru thus reduces both frustration and fuel use, and makes commuting a slightly less horrible experience. -

All this hate for the automobile and yet nobody seems to pay attention to the much worse culprits! -
A une émission de Radio-Canada, on parlait de véhicules élecltriques, dont des autobus entièrement électriques qui arrêteront à des bornes, le long de leur parcours, pour se recharger pendant 1 minute. L'expert disait que la technologie existe déjà, et que les trolley bus (et tramways j'imagine) étaient des technologies dépassées. On disait aussi que le Québec est particulièrement bien placé au niveau du moteur-roue, et des technologies de batteries, pour profiter de la nouvelle vague verte. Voici un exemple: Hybrid-Electric Design ZERO emissions (with hydrogen fuel-cell or battery-electric options) Reduce fuel costs by greater than 90% Fewer parts to maintain with all-electric drivetrain Ultra-quiet drive system reduces noise pollution 90% regenerative braking recapture Unique All-Composite Body Low floor minimizes boarding time and increases passenger safety Impact resistant composite body increases vehicle safety and reduces maintenance Low center of gravity reduces chance for roll over Light weight body reduces impact on streets Modern appearance ADA-friendly design enables all passengers to ride the bus No corrosion - composite body and stainless steel subframe Other Features Safety front door prevents passengers from walking directly in front of the bus Large windshield for increased visibility Driver footwell glass for increased safety Incremental cost paid for by fuel savings http://www.proterraonline.com/transit.asp

Driving in Montreal is an experience Posted By Marshall, Scott Updated 1 hour ago Driving in different places can be difficult to many people. The fear of not knowing where you're going can be very overwhelming. Roads you've never seen before and higher than normal traffic can lead to high anxiety. I was recently in Montreal and if you've ever driven there you'll already know it's an experience of a lifetime. The cab ride from the airport to my hotel was interesting to start with. The driver didn't use his turn signals. Most people will use them at least most of the time. It lets other road users know your intentions. In Montreal, it lets other drivers know what your plans are early enough so they can speed up and block your move. If you're in Montreal you don't signal. That way nobody knows your moves. We all know that fuel prices are higher than we would all like, so the drivers in Montreal decided to work together to save fuel. They follow each other very closely so they can cut down on wind resistance. Race car drivers call this 'drafting'. The cab driver was driving close enough to the traffic in front of them that it looked like they were being towed by the driver in front. I thought it was very nice of the lead driver, or drivers, to avoid suddenly stopping. That was nice of them, don't you think? Most drivers would understand they need to have some response time from the driver in front if they stop suddenly. Wouldn't you? You should leave more of a following distance if the driver ahead of you is unsure of where they are going so they'll have enough room to turn around as necessary. As a side note, following further back also give you more to stop if the lead driver stops suddenly. We should all know that, right? Now, I enjoy playing and watching sports like a lot of people do. I like the competitiveness of sports. Being a pedestrian in Montreal seems like it's a sport to many of the drivers in Montreal, though. When the cab driver was driving along the road and was about to enter an intersection, a pedestrian stepped off the curb right in front of us. There was no horn honking and only a slight swerve was done to avoid hitting them. Maybe you need to drive as close as possible to a pedestrian when you're driving there? I didn't see the rules for this one, so maybe I'm wrong. I may have exaggerated my thoughts here, but every event did actually happen. The bottom line here is no matter where you drive, keep space around your vehicle and communicate to other road users. Plan your route so you know where your turns are and get into the proper lane well in advance. If you do all of this, you'll be safe driving - even while in Montreal!
