Increased Safety and vignovin.com Efficiency with the Michigan Left

michLeft

A recent study carried out by traffic engineering researchers at North Carolina State University found that the use of the best site lowest priced levitra roads without left turns (known as "Michigan left" or "superstreet" design) makes for roads with "significantly faster travel times, and leads to a drastic reduction in automobile collisions and injuries." While the Michigan left has been around since the 1960s, the design is not widely used except in Michigan and to some extent in North Carolina. This study is the first significant examination of the http://www.accessibleadventuresvt.org/levitra-generic-brand benefits of this kind of intersection.

Drivers, especially those unfamiliar with the concept, may find the Michigan left to be frustrating in practice, because making a left turn in such an intersection often requires a stop, then driving a short distance and having to stop again before being able to http://www.chemistswithoutborders.org/viagra-uk join the flow of traffic in the desired direction. However, the wait times are actually less than if the intersection was configured with all the needed delays necessary to implement four-way left turns (which usually stop all other traffic to allow the lefts).

Left turns across oncoming traffic is eliminated with this kind of intersection, which allows the 5 mg viagra intersection to cycle more quickly, so that more cars can move through it, and less time is spent idling while waiting at a red light. Superstreets are an inconvenience to drivers on the minor road, but are useful where little of the traffic on the minor road is free samples of levitra through traffic. Michigan lefts are a better design for true four-way intersections with high-volume roads.

In practice, the lights on saltlakewebcentral.com the roads that employ this kind of turn are also timed so that flowing traffic on the major street can continue along without stopping. This can mean that, at busy commuting times, taking the surface street can actually be faster than taking the expressway. (In this case, I'm speaking in part from personal experience.)

To be clear, the application of this design is not universal. It would be hugely wasteful to use this kind of design for every intersection. But for high-volume roadways, the delays at the intersection are shortened for all drivers, not just those making left turns.

Like roundabouts, which are often opposed at first because most drivers are unfamiliar with them and initially find them confusing, a slightly more complex design can be more beneficial to traffic flow as well as to buy cialis online without a prescription safety. Whether this study will make a difference and see the adoption of how you get pfizer viagra this practice in other regions remains to be seen.

what about the pittsbur left?
written by sarah, February 08, 2011
since the streets are narrow, drivers just let the first few left turn folks go on and go...letting the indian generic levitra traffic behind them not get jammed up. I call it being considerate. It was fun to drive in that city because of this practice..cuts down on gridlock...though i never timed it.

The Jersey Left
written by Philosoherott, February 08, 2011
In New Jersey we keep traffic moving by using Jug Handles. Much safer and cost of cialis it keeps the left lane the fast lane. People hate them because they are not use to them but it WORKS! I never missed them so much till I moved away from Jersey. I hate people that hit there blinkers at the last second to make a left across 2-3 lanes and you sit and sit and sit... does not happen in NJ with jug handles.

As one who lives in Michigan and has dealt with the atrocity of the 'Super Street' (Hall Rd.) Can tell you first hand they suck. Yes, they make travel easier in the straightaway, but trying to ordering cialis merge (9 time out of 10 there is no merging lane) let alone cross four lanes of traffic is deadly at best even in the lightest of traffic. The only thing more of http://www.jubileecampaign.nl/levitra-label a waist of time and road management are Jersey lefts.
Give me roundabouts and long lights any day.

Cairo, Egypt has, over the past 15 years, converted almost the whole city to these type of left hand turns because traffic signals are totally ignored by the driving population. Thus, these snake turns are the only way to get traffic to move at all.
