A four-to-six week pre-study data <br /> collection began the week of Sept. 11. This pre-data collection will enable the consultant to <br /> compare this data with data collected when the ramp meters are shut down. In total, both the <br /> "before" and "after"data collection should take about 10 to 12 weeks. <br /> Q: Will all the ramp meters be turned off? <br /> A: Yes, all 430 ramp meters will be shut off during the study. <br /> Q: Are you going to tell the public when the shutdown is? If so, why? <br /> A: The Ramp Meter Study Advisory Committee decided to notify the public a week in <br /> advance of the shutdown. The consultant decided that they will take into account the impact <br /> of any type of anticipatory behavior. The consultant estimates that it will take one to two <br /> weeks for traffic to settle down when the meters are turned off The consultant believes that <br /> alerting the public could speed up this transition time. <br /> • <br /> Q: What will the study cost? <br /> A: The study will cost $651,600. <br /> Q: What are the study objectives? <br /> A: Study objectives include: <br /> • To fully explore the impacts of ramp metering on freeways, local roads, and on transit <br /> operations. <br /> • To identify the public perception of ramp metering. <br /> • To compare Minnesota's ramp metering system and timing strategies with other <br /> regional systems across the country. <br /> Q: What will the consultant be measuring? <br /> A: The consultant will study four freeway corridors that have been chosen as being <br /> representative of the system. The location of these corridors will not be made public, so as to <br /> maintain the integrity of the data. <br /> The consultant team will collect data that will help it evaluate the impacts of ramp metering <br /> on travel time, safety, travel time reliability/predictability, the environment and energy <br /> • <br /> An equal opportunity employer <br />
