  2. Presentation Outline • General Background • Rubbernecking • Objective • Area of Study • Data Analysis • Mechanical System • Part 1 • Part 2 • Triangle Theory • Results • Questions

  3. Congestion Problems Los Angeles ranks highest in total and per-capita congestion delays every year. 60% of all traffic congestion is due to incidents. Accidents (vehicle to vehicle or vehicle to object)

  4. Rubbernecking • What is it? • Rubbernecking is when drivers on the opposing side of an incident are curious and distracted by the incident, therefore slowing down. • Leads to congestion and/or accidents

  5. Research Objective This study concentrates on creating a mechanical system that identifies bottlenecks due to rubbernecking and evaluates the impacts they have on speed reduction.

  6. Area of Study • Interstate 5 • Interstate 10 • Highway 101 • Interstate 210 • Interstate 405 • Interstate 605

  7. Data Analysis • PeMS (http:pems.dot.ca.gov/) • Historical Real-Time Traffic Data • Timestamp, station, District, Freeway #, Direction of Travel, Total Flow, Average Speed… ext. • Incident Data

  8. Mechanical System • Microsoft Visual Studio • Identifies Bottlenecks Caused by rubbernecking. • Part One • Locates the opposing side of traffic and collects it’s real time traffic data. • Part Two • Analyzes the data and determines where bottlenecking had a major effect on the traffic speed.

  9. Databases • Two databases were created • One has four tables • Freeways Table • Stations Table • Speed date Table • Incidents Table • Five-Minute data

  10. Part One

  11. Part Two

  12. Triangle Theory Find possible accident station Find possible accident start time Search for occurrences of bottleneck

  13. Ideal Case

  14. Triangle Theory Cont…

  15. Continuous Low (Half Triangle)

  16. Prior Influence

  17. Similar Shape (Low Speed)

  18. Results • Parameters: • Start Date: January 2, 2011 • End Date: December 30, 2011 • Minimum Duration: 30 minutes • Maximum Duration: 600 minutes • Days: Monday through Friday • Length Before incident: 2 miles • Length After incident: 2 miles
