• Abstract:
  In an effort to reduce fatalities resulting from traffic collisions, California’s Strategic Highway Safety Plan identified ; 16 Challenge Areas under the State Highway Safety Plan. Improper driving decisions about the right of way and ; turning became the focus of Challenge Area 5 (CA-5). To better address the needs in this area, Caltrans staff ; proposed a research project that considers the following priorities outlined in the plan: ; 5.1 Develop and encourage implementation of a systematic approach to the identification and improvement of ; existing and potential “high-crash concentration locations” involving improper driver decisions about rights ; of way and turning. ; 5.4 Explore and implement approved technologies being used by other states and countries to reduce severe ; traffic collisions associated with turning and lane changing on high-speed, multilane facilities. ; 5.5 Expand the use of existing technology-based tools and strategies that have been demonstrated to correct or ; minimize the traffic operating conditions which are a primary cause of collisions related to abrupt lane ; changing in the vicinity of freeway merge and diverge points. ; 5.7 Support new and ongoing research and development projects associated with in-vehicle communication ; and information technologies to help detect and warn drivers of potential collision with other vehicles in ; the adjacent lane during lane change maneuvers. ; In support of the proposed research project, this Preliminary Investigation focused on identifying strategies and ; technologies to reduce crashes and fatalities by improving the performance/decision making of drivers who are ; confronted with complex infrastructure and/or operating conditions. To carry out this investigation, we summarized ; completed domestic and international research and research in progress. We also surveyed transportation agencies to ; identify best practices for conducting crash investigations using a multidisciplinary team and contacted ; transportation agencies directly to learn more about the countermeasures used to improve safety on complex ; freeways.
