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

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

6.  Interstate 5  Interstate 10  Highway 101  Interstate 210  Interstate 405  Interstate 605

7.  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.  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.  Two databases were created  One has four tables Freeways Table Stations Table Speed date Table Incidents Table  Five-Minute data

13.  Find possible accident station  Find possible accident start time  Search for occurrences of bottleneck

19.  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
