    How to reduce consumption 10% and emissions 22%

    And it doesn't involve impossible technologies or driving foreign mini cars:

    BENEFITS OF EXCELLENCE IN TRAFFIC SIGNAL OPERATIONS
    Traffic signal operations must be viewed as a continually evolving process with the ultimate goal of improving the level of operations nationwide. If the nation supported its signals at an A grade level, quality of life and protection of the environment would benefit significantly, including:

    • Reductions in traffic delay ranging from 15–40 percent; reductions in travel time up to 25 percent; and reductions in stops ranging from 10–40 percent.
    o For example, a driver who spends two hours in the car commuting to and from work and running errands would save 117.5 hours per year as a benefit of improved signal timing.


    • Reductions in fuel consumption of up to 10 percent.
    o A driver who uses one tank of gas a week would save five full tanks per year per household, or approximately $240.14 Nationwide, this would amount to a savings of almost 17 billion gallons of motor fuel per year.


    • Reductions in harmful emissions (carbon monoxide, nitrogen oxides and volatile organic compounds) up to 22 percent.


    Note: Spending less than 1 percent of the total expenditure on highway transportation would lead to a level of excellence in traffic signal operations. This investment strategy would leverage an investment with a 40:1 benefit-cost ratio and would result in benefits of as much as $45 billion per year. This corresponds to a price of less than $3 per U.S. household resulting in savings of $100 per household per year.

    I'm forwarding this to the mayor of Seattle. The lights around here seem timed to impede traffic rather than facilitate it.
    "The blood-dimmed tide is loosed, and everywhere the ceremony of innocence is drowned;
    The best lack all conviction, while the worst are full of passionate intensity. "

    W.B. Yeats- 1919

    Finally!!!!
    There seem to be 3 standard union responses to any criticism of the UAW:

    1) You're just jealous
    2) If the unions go away, the middle class will disappear
    3) If the unions go away, everyone will become a company slave

    None of them are true.

    do you realize how much money it takes to earn a grade A rating on the service level of a road? it is alot more than just traffic lights. alot of roads run around C and D because theres just no money. and, they cant design a road to be a perfect A 100% of the time, its just not economically feasible. why are you going to plan a road to be perfect when its highest loads are at christmas? the road then becomes severely underused the rest of the year and that is even more money wasted through increases maintenance and the like than letting it run the way it is. most roads are designed to handle 80-90% of the maximum load it will see.

    theres a reason why lights are timed the way they are, too much red on one side and traffic gets backed up beyond the turning lane on the other and impedes straight traffic. this is also causes for a turning lane to not fully empty before the light turns back to red. to much green on the same side and the same thing happens on the other side. it is a delicate balance that takes alot of time to develop and construct. there are many calculations that are done to determine how lights are timed, how long turning lanes are, how wide lanes are, how many there are, how big shoulders are, etc.

    theres alot of work being done to fix such situations, you just dont hear about it. look at your respective states highway department sites, youll fine them. these things take years to do.

    Chakiz24, I have the solution.
    Let the auto companies build the roads and the government build the vehicles. Voila, problem solved overnight. No longer will there be modern computerized 21 century cars running down mid 20th century roads. The problem will correct itself overnight.

    As if the Environmentalists would sit back, fold their arms, nod, and be happy with just that.

    We can also cut fuel consumption by approximately 20% by simply slowing down to 55 mph on the highways. Of course, this reliably results in people going ballistic over the thought.

    Are roundabouts more efficient, overall, than intersections?

    as long as the traffic isn't heavy, there no problem

    come to think of it for a better traffic flow, maybe we should revive some cancelled freeways/expressways projects like the Bushwick Expressway in Queens and Brooklyn http://www.nycroads.com/roads/bushwick/ Lower Manhattan expressway http://www.nycroads.com/roads/lower-manhattan/ Spadina and Scarborough expressways in Toronto, etc...

    Yes. But, I suspect most Americans wouldn't know what to do with one if they saw one.

    The government has passed laws that require the automakers to build new vehicles that produce a tiny percentage of the pollution that they once did. Then you drive this technological wonder out to the freeway and sit in a traffic jam for an hour. California and Governor Schwarzenneger are particularly comical. Despite the huge revenue obtained from gas and vehicle taxes the roads of California are woefully inadequate and contribute huge amounts to increased fuel consumption. Governments being governments they ignore the reality of this situation and rail against the vehicle manufacturers, conveniently deflecting the blame and wasting money on ill conceived programs like ethanol from food. You will not soon see any legistlation requiring that the roads are built to handle the actual amount of traffic flow.

    The LA Times published this from me on 4/10/2005:

    Every time I drive under one of the ancient overpasses on Interstate 5 with a date such as 1947 cast into the concrete I wonder how a state with so many people and so much money could have such a lousy road system.

    Instead of the silly gasoline tax shuffle proposed by the Democrats in Sacramento, we need to double gasoline and diesel taxes.
    I drive far more than most people - 31,000 business miles last year- and would happily pay twice the $730 I paid in gasoline taxes to have good roads and highways. The higher fuel taxes would be partly or completely offset by savings in travel time, vehicle maintenance, and fuel usage.

    Better roads would also dramatically reduce the mental and physical wear and tear associated with driving in California. Of course, we need to demand that all of the fuel taxes go to roads.

    Coordinating signals and such is a big business, and much such work is currently underway, at least here in soutehrn California.

    Quebec got one of the higher gas taxes in Canada and the amount from the taxes are spended elsewhere, meanwhile some favor a return of tolls accorings to various polls in this French article http://www2.canoe.com/infos/quebecca...11-053601.html
