Project Objectives

• Document physical characteristics, performance,
  traffic control and access management practices
  along the corridor
• Survey El Segundo area employees who drive the
  PCH corridor for their observations about
  corridor traffic conditions and impediments, and
  to solicit suggestions for improving traffic flow
• Prepare a Corridor Improvement Plan that will
  include a list of short-term, low-cost
  improvements that can be implemented to improve
  traffic conditions on the corridor

Travel Survey Findings

• Reasons for congestion on study corridor
• Too much traffic
• Poor signal timing
• Insufficient roadway capacity
• Most congested locations
• AM Between Anita St and Rosecrans Ave
• PM Between Anita St and El Segundo Blvd
• PM Between Hawthorne Blvd and Crenshaw Blvd
  (eastbound approach to Crenshaw Blvd)
• Rosecrans Ave intersection

13
Study Conclusions

• Some corridor segments and intersections are
  over-saturated
• Signal timing and coordination are perceived to
  be inefficient
• Critical choke points
• Rosecrans Avenue
• Manhattan Beach Boulevard
• Pier Avenue/Aviation Boulevard
• Torrance Boulevard
• Lane drops on SR1 at Catalina Avenue, Rosecrans
  Avenue Crenshaw Boulevard

14
Study Conclusions (cont.)

• Left turn storage is inadequate at several
  locations
• Section of SR 1 between Artesia Blvd and Anita
  Street experiences higher than average collision
  rates on-street parking may be a contributing
  factor
• Corridor capacity is reduced and potential safety
  hazards are created by
• Lack of bus turnouts
• Closed travel lanes due to construction or
  maintenance
• Lanes blocked by delivery/garbage vehicles

Project Takeaways

• Public input was a key element of the analysis
  process
• An online travel and opinion survey and a trip
  diary were used to solicit public input
• Benefits of the study
• - Communication between public and public
  agencies was enhanced
• - Communication and coordination between
  jurisdictions was enhanced
• - Improved understanding of corridor conditions

22
Project Takeaways (cont.)

• Benefits of a user-based analysis
• - Creates goodwill
• - Quantifies relative importance of issues and
  conditions as viewed by the public
• - Confirms known issues and conditions
• - Identifies issues/conditions that may not be
  apparent to public agencies

23
Project Takeaways (cont.)

• Benefits of the online survey and trip diary
• - Efficient distribution, tabulation and
  summarization
• - Easy to participate
• - High participation relative to other public
  input methods

24
Project Takeaways (cont.)

• The study succeeded in identifying low-cost,
  short-term improvements
• There is merit for conducting a user-based
  analysis
• - Provided opportunity for users to proactively
  have their voice heard
• - Commuting experience has value
• - Validated known issues
• - Identified relative importance of various
  conditions and possible solutions
• - Identified problems that may not be known to
  public agencies
