Review of Temporary Traffic Control Devices
Clark Pavement Marking Company – North Carolina

Beaubien Engineering was engaged to review the circumstances concerning a crash on southbound I-95 near Mile Marker 8 in North Carolina. Specifically, Beaubien Engineering was asked to address these questions:

  1. Does the vertical curve restrict the visibility of traffic control devices and southbound motor vehicles for southbound travelers?
  2. Did the traffic control devices placed by Clark Pavement Marking force motorists to merge too soon into the right ?
  3. Did the traffic control devices place by Clark Pavement Marking conflict with guidance for work zone signing published by the North Carolina Department of Transportation?
  4. Were the supplemental traffic control devices placed by Clark Pavement Marking detrimental to work zone safety?
  5. Would the moving caravan pavement marking operation have been safer during hours of darkness?
  6. Can an individual working under the supervision of an engineer, through the application of procedures and criteria established by the engineer deploy traffic control devices in the field?

We visited the site to observe traffic operations. Standards and guidelines referenced in our review included the Manual on Uniform Traffic Control Devices.

Pedestrian Safety Study

Chicago Heights School District – Chicago Heights, Illinois

Beaubien Engineering was engaged to evaluate the Traffic controls used in the work zone on 16th Place in Chicago Heights, Illinois, during the repair of a break of a water line serving Washington-McKinley School on October 23, 2013.  Specifically, Beaubien Engineering evaluated the safety and effectiveness of the work zone traffic controls and their compliance with the requirements of the Manual of Uniform Traffic Control Devices.

Interchange Traffic Safety Review

I-70/State Route K-18 – Geary County, Kansas

Beaubien Engineering reviewed the crash history and existing traffic control devices at the interchange of I-70 and State Route K-18 in Geary County, Kansas. The assignment was to answer four questions:

  1. Is the traffic signing consistent with the requirements of the Manual on Uniform Traffic Control Devices?
  2. Is the traffic signing consistent with the Kansas Signing Manual?
  3. Is the traffic signing sufficient to warn motorists of unusual signing at the K-18/I-70 eastbound off ramp intersection?
  4. Did the traffic signing adequately consider human factors and driver expectations?

We visited the site to observe traffic operations.  We reviewed the traffic crash records for the interchange to determine if there is a pattern of traffic crashes at the interchange that could be addressed with improved traffic control devices.  Standards and guidelines referenced in our review included the Manual on Uniform Traffic Control Devices, the Kansas Signing Manual, the Highway Safety Manual, and the Federal Highway Administration Publication No. FHWA-SA-07-015 Crash Reduction Factors.

Security Credit Union Traffic Impact Study
Security Credit Union – Flint, Michigan
May 2015 to August 2015

Prepared a traffic impact study for the development of the Security Credit Union Headquarters Campus development in Grand Blanc Township, Genesee County, Michigan. Data collection on existing traffic conditions included hourly traffic volumes, turning movements, tabulation of traffic gaps, and percentage of commercial vehicles. Trip generation, traffic assignment, and capacity analysis studies were included. Provided support for public agency review of traffic impacts and evaluation of roadway improvements needed to accommodate the traffic from the development

Pine Creek Ridge Traffic Survey – Livingston County, Michigan
Pine Creek Ridge Homeowners Association
October 2013 to April 2014

To control traffic volumes and reduce speeding on its streets, the Pine Creek Ridge Homeowners Association requested approval from Genoa Township to convert streets in the subdivision from public ownership to private ownership.  To gain an understanding of how these streets are currently being used, Beaubien Engineering was retained to gather information on traffic volumes, speeds, and direction of travel

Traffic Safety Analysis of Gasoline Retail Traffic Operations – Costco Wholesale
August 2013 to February 2014

Provided traffic engineering expert witness services to defend Costco in litigation involving an injury sustained by a customer at their Shelby Township, Michigan retail operation.  Analyzed the gasoline retail operation to determine if the design of traffic operations provided a reasonably safe environment for gasoline retail customers.

Davison Pedestrian Safety Study
June 2012 to Present

Worked with Focus Hope in Detroit to improve the safety of pedestrians crossing Davison, a seven lane state arterial along the southern border of Focus Hope Village. This arterial has a daily traffic volume of 40,000, so it is difficult for pedestrians to find a gap in traffic to cross the seven lanes safely.

Statewide Road Safety Audits for Michigan Department of Transportation

Connected Vehicle Demonstration
April 2010 to November 2011

Michigan Department of Transportation project to demonstrate wireless communications between a test vehicle and traffic signals. Traffic signal timing information has the potential to reduce right-angle crashes at intersections. The wireless communications provided an in-vehicle display of traffic signal timing at the upcoming intersection and the recommended speed to arrive at the signal during the green phase
