Research Projects

1999, Acceleration Values for Turning Vehicles, Testing to determine an average acceleration rate for vehicles executing a left turn.

1995 – 1996, Alternative Accident Site Dimensioning Devices, Testing to evaluate Electronic Total Stations & Laser Measuring Devises.

1991,Two-Dimensional Computer Simulations of Collisions using EdSMAC & EdSVS computer programs, Develop an instructional aid for police investigators to animate single and multi-vehicle collisions.

1991,“Crush” Based Speed Analysis, Develop a training manual for police investigators in the area of “Crush Based” collision analysis using the EdCrash computer software.

1990, Tire Mark Speed Analysis, Determine the most accurate method for determining vehicle speed from residual tire marks on a road surface.

1989, Damage Based Computer Analysis Software, Research and testing of computer software for collision analysis

1989, Responsible for the computerization of the Traffic Division & Investigation Unit, Completed a project to revamp the inner workings of the Traffic Division and Investigation Unit to a completely computerized entity.  Databases were created to track statistics relating to collision types and locations.  Hand drawn scale diagrams were replaced entirely with computer generated diagrams.  Standard Operating Procedure manuals were re-written to include manuals on the new computer based systems.  Investigators were trained in the use of the new computer based systems.  Databases were created to organize and search accident diagrams and reports.  A database was created to organize scale models of vehicles, which were created using a CAD system.  Templates for all quarterly, semi-annual and annual reports were created using computer-based graphics and processing programs.  The FARS (Fatal Accident Reporting System) for Baltimore City Police was converted from a logbook to a computer driven system.  Inventory databases were created to track the equipment assigned to the Traffic Division.  Clerical staff were trained in the use of “Word Processing” systems that replaced typewriters.  Template reports were created for use in collecting field data which would later be input into the computer systems)

1988, Measurement of Tire/Roadway Frictional Coefficients, Comparative testing of computerized accelerometers vs. conventional methods to determine roadway frictional values.

1988, Computer Assisted Drawing Systems, Develop a computer assisted drawing program for use by the Traffic Investigation Unit of the Baltimore City Police Department to diagram all investigated accidents.
