What are Ramp Meters? 3 Traffic controls that regulate traffic flow entering a highway (Source: Reference 6)

Uses of Ramp Meters Reduce congestion Improve throughput Reduce travel time Improved travel time reliability Ensuring safety of vehicles 4 (Source: Reference 6)

Types of Ramp Metering Fixed time –Pre-timed meter cycle based off of past data Responsive –Meter cycles vary depending on changes in traffic conditions –Isolated –Coordinated 5

Meters Across the US Seattle: 232 Portland: 110 LA: 1478 Phoenix: 122 Salt Lake City: 23 Denver: 46 Arlington: 5 Minn-St. Paul: 444 Milwaukee: 122 Chicago: 117 New York: 75 N. Virginia: 26 Implemented - Responsive In Progress - Responsive 6 In Progress - Fixed Ohio: 34

Networking Received information from Mn/DOT, WSDOT, ODOT Mn/DOT uses traffic responsive WSDOT uses traffic responsive with fuzzy logic algorithm ODOT uses fixed timings 7

Scope of Study Conducting research on the study site (I-275) by gathering data using traffic counter and GPS device Criteria –Elevated locations nearby for placing the camcorder to capture the traffic –Location should be busier in the peak hours than the normal flow of freeway Analyzing traffic during the peak hours Investigating and observing both a single and two lane ramp implementation 8

Goals Analysis of data collected Investigate –Effectiveness of ramp implementation –One or two lane ramp metering Successfully run simulations on VISSIM Present and complete deliverables 9

Tasks Utilizing the GPS software (QTravel) and traffic counting software (PetraPro) Processing of data collected from GPS and traffic counting device Generate VISSIM network model using processed data Analyze results 10
