Study Data Analysis Mechanical System Part 1 Part 2 Triangle Theory
Results Questions Slide 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) Slide 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 Slide 5 This study concentrates on
creating a mechanical system that identifies bottlenecks due to
rubbernecking and evaluates the impacts they have on speed
reduction. Slide 6 Interstate 5 Interstate 10 Highway 101
Interstate 210 Interstate 405 Interstate 605 Slide 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 Slide 8 Microsoft Visual
Studio Identifies Bottlenecks Caused by rubbernecking. Part One
Locates the opposing side of traffic and collects its real time
traffic data. Part Two Analyzes the data and determines where
bottlenecking had a major effect on the traffic speed. Slide 9 Two
databases were created One has four tables Freeways Table Stations
Table Speed date Table Incidents Table Five-Minute data Slide 10
Slide 11 Slide 12 Slide 13 Find possible accident station Find
possible accident start time Search for occurrences of bottleneck
