3 What are Ramp Meters? • Traffic controls that regulate traffic flow entering a highway (Source: Reference 6)
4 Uses of Ramp Meters • Reduce congestion • Improve throughput • Reduce travel time • Improved travel time reliability • Ensuring safety of vehicles (Source: Reference 6)
5 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
6 Meters Across the US Seattle: 232 Minn-St. Paul: 444 Portland: 110 Milwaukee: 122 Ohio: 34 New York: 75 Chicago: 117 Salt Lake City: 23 Denver: 46 N. Virginia: 26 LA: 1478 Phoenix: 122 Arlington: 5 Implemented - Responsive In Progress - Responsive In Progress - Fixed
7 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
8 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
9 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
10 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
