3. Introducing Ramp Meters Ramp metering - the process of facilitating traffic flow on freeways by regulating the amount of traffic entering the freeway, through the use of control devices on entrance ramps.Ramp metering - the process of facilitating traffic flow on freeways by regulating the amount of traffic entering the freeway, through the use of control devices on entrance ramps. Control devices are normally stoplights that let one car at a time through at regular intervals.Control devices are normally stoplights that let one car at a time through at regular intervals.

6. Facts Transportation officials did a study for the public and legislators finding that ramp meters cut crashes by 1,280 per year. This comes from comparing crashes in 1988 (without metering) to crashes in 1996 (with more widespread metering). WA DoT claims that during the ramp study there was a 40% decrease in the rate of accidents per miles traveled.Transportation officials did a study for the public and legislators finding that ramp meters cut crashes by 1,280 per year.

Ramp meters don’t actually waste that much time, even in a very busy person’s schedule On average, drivers wait less than two minutes at a ramp meter, even during the morning and evening rush hour.Ramp meters don’t actually waste that much time, even in a very busy person’s schedule On average, drivers wait less than two minutes at a ramp meter, even during the morning and evening rush hour.

7. More Crazy Facts Traffic flow is less stop and go WA DoT reports that typical increases after ramp meters are installed ranged from 73 to 92 percent, more than 20 miles per hour.Traffic flow is less stop and go WA DoT reports that typical increases after ramp meters are installed ranged from 73 to 92 percent, more than 20 miles per hour. Freeway capacity is increased WA DoT study also finds that metering makes it possible for the freeways to carry 29 to 42 % more vehicles than would have been possible without metering. This means that about 800 more vehicles per lane per hour would be on the freeway.Freeway capacity is increased WA DoT study also finds that metering makes it possible for the freeways to carry 29 to 42 % more vehicles than would have been possible without metering.

Ramp meters actually saves money By building ramp meters, taxpayers aren’t required to pay for the costs associated with building new lanes because of congested traffic conditions. Instead, the congestion is minimized by metering.Ramp meters actually saves money By building ramp meters, taxpayers aren’t required to pay for the costs associated with building new lanes because of congested traffic conditions.

10. Data Analysis By the previous graph, it is possible to see that ramp metering allows for increased capacity on highways and interstatesBy the previous graph, it is possible to see that ramp metering allows for increased capacity on highways and interstates Thus, more cars are able to move from one point to another with the help of ramp meteringThus, more cars are able to move from one point to another with the help of ramp metering With increased capacity, the need to expand freeways to more lanes is obliterated.With increased capacity, the need to expand freeways to more lanes is obliterated.

11. Conclusion In summary, data studies and statistics confirm that ramp metering actually help facilitate traffic flow on freeways.In summary, data studies and statistics confirm that ramp metering actually help facilitate traffic flow on freeways. Therefore, ramp metering should be supported as the most effective way of monitoring congestion during rush hour conditions.Therefore, ramp metering should be supported as the most effective way of monitoring congestion during rush hour conditions.
