These seem to be very popular. I don't know how the company is doing financially, but I see these all over DT and the Beach areas. Pretty good idea because may residents at the beach don't own vehicles.

I hope SD gets a bike sharing program like Bixi one day. Seems like a perfect city for it.

Car2Go provides an excellent service here in DC. I usually use it once or twice per week, when our buses and metro system aren't running as frequently. You can either pay $20 for a taxi or spend $5 (they charge by the minute) for these Car2Go vehicles.

FedEx and UPS have electric trucks. I see them scooting around town quite often. As does Staples.

And the Mitsubishi i is an awful car. Invest in a Ford Fusion Energi. 8 MPGe more than a Chevy Volt and 13 (!!) MPGe than a Toyota Prius.

Measuring Transport System Efficiency

.....

There are several possible ways to measure transport system efficiency, which can result in very different conclusions about what solutions are optimal:

Conventional roadway planning evaluates roadway efficiency based primarily on motor vehicle travel speeds. From this perspective increasing transport system efficiency requires increasing roadway capacity and design speeds. This supports roadway expansions.

Traffic network planning evaluates roadway efficiency based on automobile access, and so recognizes the reduced travel distances that result from more connected road networks and two-way streets. This supports efforts to increase both traffic speeds and road network connectivity.

Multi-modal transport planning recognizes that travel demands are diverse because not everybody can drive, and transport costs (including road space, parking, vehicle, travel time, accident risk and environmental costs) and benefits vary. For example, it is inefficient if inadequate transport options forces parents to chauffeur children to school if they would prefer to walk or bicycle, or forces commuters to drive when public transit is overall cheaper. From this perspective transport systems are most efficient if they support and encourage use of resource-efficient modes, so users choose the most efficient option for each trip. This supports complete streets policies, including bike- and bus-lanes, and other efforts to improve and encourage use of resource efficient modes.

Accessibility-based transport planning recognizes that mobility is seldom an end in itself; the ultimate goal of most transport is access [PDF] to services and activities such as education, employment, shopping and recreation. Several factors can affect accessibility including mobility (travel speed and affordability), the quality of transport options, transport network connectivity, land use accessibility, and mobility substitutes such as telecommunications and delivery services. From this perspective, transport systems are most efficient if they increase road network connectivity, support efficient modes, and encourage more accessible land use. This justifies integrated planning that increases transport network connectivity and supports more accessible and multi-modal community development.

Economic efficiency refers to the degree that consumer benefits provided by a good exceeds the costs of producing that good (roads can be considered a good consumed by users). From this perspective roads are most efficient if managed or priced to favor higher-value trips and more resource-efficient modes over lower-value trips and less efficient modes. This can justify priority treatment of freight and service vehicles (they tend to be high value), and public transit and high occupant vehicles (they tend to be space efficient), or even better, congestion pricing (road tolls that are higher during peak periods) that test users’ willingness to pay for scarce road space, which allows higher value trips and more efficient modes to outbid lower-value trips and more space-intensive modes.

Planning efficiency refers to the degree that planning activities are comprehensive and integrated, so that individual, short-term decisions support strategic, long-term goals. This is functional way to develop more accessible and economically efficient roadway systems. From this perspective transport systems are most efficient if planned, designed and managed to support strategic objectives. For example, efficient planning justifies special truck lanes if that supports regional industries, bus lanes and pedestrian improvements that support transit oriented development, streetscaping that supports local commercial district redevelopment, and constraints on urban fringe roadway expansion if that support strategic objectives to encourage more compact development.

That is a neat bridge. Gave me a heck of an idea for my own pipe dream for the Burgh. Could the Westinghouse Bridge support an el train?

NYC Subway Infographic Posters

Read More: http://www.kickstarter.com/projects/...raphic-posters

Quote:

NYC Subway Infographic Poster set shows each subway line in clear crisp design as it exists geographically with stats and description.

- The subway map is usually not really a map but rather a diagram as it is not a literal representation of the subway. Each subway map from cities all around the globe all distort the city and distort the subway lines for the purpose of visual clarity. This is great for someone running to catch a train and not knowing where to get off.

- This series of posters tries to flip the original rational for clean design on its head. Instead of creating a map showing the routes of each line abstracted to fit into a small map each poster shows just one train line by itself, stripped away from its context, with a description and statistics provided. Why do it this way? I wanted to show the viewer something they see everyday but in a completely new, almost unrecognizable way; the way it actually looks.

The ELF is designed with the busy commuter in mind. The ride height puts you in sight of other drivers while the body is still slim enough to navigate bike trails. There is plenty of room to stash your laptop case and pick up several bags of groceries on the way home. Recharge the removable battery pack by parking your ELF in the sun or by plugging it in to a standard outlet. Upgrade to a more powerful solar panel to stay off grid or add a NuVinci 360 hub to ease your ride. Additional upgrades and features will be available.

2013 rolls royce wraith - 03.2013
 
After seeing spread silhouette of the new model profile in the web, i took my conclusions, now you think if it is a Rolls Royce or not, I mean a BMW, the rear could be a GT as well...

Pretty cool. My commute would take just 14 minutes by car (except for that little thing called traffic). I take transit now tho, it takes 40 minutes and is maybe 40% longer. Really should start biking when the snow melts (if I've got money for a bike), takes as long as the subway/bus!

Could These Crazy Intersections Make Us Safer?

Read More: http://www.theatlanticcities.com/com...us-safer/4467/

Quote:

Geometry tells us that the traditional four-way intersection is inherently dangerous. When you plot all of the potential points of conflict on a diagram – and transportation engineers actually do this – it turns out that vehicles have 32 distinct opportunities to collide into one another at the nexus of two two-lane roadways. Cars can crash into each other while merging or diverging from a given lane. Then the worst action happens right in the middle of the interchange, at that perilous point where vehicles turn left across oncoming traffic.

- With that geometry in mind, it becomes clear what we need in the holy grail of intersection design: a scheme that would eliminate left-hand turns while still enabling drivers to move in all four directions. The basic roundabout does this, with only eight relatively less harmful points of conflict. The challenge is to translate that same idea onto much busier roads. You may already be familiar with the “Michigan Left,” also known as the “median U-turn,” which solves this problem by requiring drivers to pass through an intersection, make a u-turn and then re-approach it from the opposite direction, ultimately making a safer right-hand turn. The concept is also intended to improve traffic flow by eliminating that pesky left-turn cycle at the light.

Vehicles are the only kind of traffic that is considered traffic. She actually does have one video where pedestrians appear for a moment.

Hear, hear. Just like with all the roundabouts that have sprung up all over Sweden in the last 15 years.

Rapid Commute System is a short-haul commuter carrying system that consists of especially modified electric (or diesel) trains that would carry commuters; their passengers and their vehicles onboard, similar to how ferryboats carry drivers and their vehicles across bodies of water. Commuters would drive their vehicles themselves onto the train using specially designed ramps and drive from boxcar to boxcar inside the train, until they reach the front. Other commuters would follow behind. The commuters would turn off their engines and stay in their vehicles while the train carries them to their destination. At the end of the trip, the commuters would drive themselves off the train. This system would allow commuters to avoid driving on the freeways, thus eliminating traffic jams.

Awful idea. Combines the inconvenience of adhering to a transit schedule with the inefficiency of car storage.
