Traffic Accident Reconstruction

Traffic accident reconstruction is the effort to determine, from whatever resources are available, how an accident happened. A traffic accident reconstructionist must be familiar with the application of a wide range of mathematics and specialized aspects of vehicle technology.

Because of the wide range of knowledge required by the accident reconstructionist, voluntary certification is available through the Accreditation Commission for Traffic Accident Reconstruction. ACTAR certification includes education, work experience, and successful completion of a comprehensive examination.

Accident reconstruction deals with:

  • kinetic energy
  • conservation of momentum
  • time-distance calculations
  • physical evidence from road and vehicle
  • crash scene photography analysis
  • lamp analysis
  • skid analysis
  • airborne analysis
  • vehicle data and research
  • damage assessment
  • vehicle damage location, qualification and quantification
  • approach, impact and departure angles
  • approach speed calculation,
  • impact calculations and Delta-V calculation
  • post impact speed calculation

Dr. McElroy specializes in motor vehicle technology and accident reconstruction. This typically entails physical inspection of the damaged vehicles, examination of the accident scene, and reconstruction of collision events using engineering calculations based primarily on momentum, energy, and restitution equations.

Vehicles may include passenger cars, light trucks, commercial vehicles, bicycles, and motorcycles. Information on pre-crash, crash, and post-crash (the 3 phases of a crash) is compiled to best determine how the event (accident, collision, failure) happened. Issues investigated include:

Motorcycle going wrong way on divided suburban street.

Takata Recall Affects 46 Million Vehicles in U.S.

Takata’s airbag recall affects over 46 million U.S. vehicles. As of June 2017 65% HAVE NOT been replaced. (Reuters)

If unable to promptly get a replacement and worried about what could happen in a crash, then you can request from NHTSA to install an airbag On-Off Switch. Here is the NHTSA link: http://www.safercar.gov/Vehicle+Shoppers/Air+Bags/ON-OFF+Switch+Requests

Airbag Recall Technology

When the inflator assembly is activated, sodium azide produces nitrogen gas which flows through the filter screen and into the airbag. Time between crash detection and complete airbag deployment is approximately 0.05 seconds. Typical airbag deployment speed is 200 mph. If the inflator assembly is structurally defective the inflator assembly can explode,

Vehicle Air Conditioning System Benefits:

An Efficient vehicle air conditioning system will reduce high cabin temperature by cooling effect if heater blower fan vent system is set to recirculation mode. If the evaporator fan (blower fan for cabin) is producing warm air from vents then the air conditioning system is likely to need service maintenance.

Enhance driver and passenger safety by maintaining a comfortable cabin temperature in hot working conditions to reduce risk of heat exhaustion. Cabin compartment air is chilled by heat transfer to produce a cooler climate for more comfortable fresh environment

Cab Temperature control Improves working environment for operators of mobile plant increasing comfort and reducing fatigue.

Maintain vision by keeping the windscreen demisted. Some systems can reverse the flow of refrigerant to provide heating as well as cooling.

Filtration of air entering the passenger compartment cab reducing dusts and pollution

Dehumidifying – Drying of the air circulating in the passenger compartment

Enhancement of vehicle security allowing windows to remain closed in hot weather

Strict Legislation applies to the servicing of Vehicle Mobile Air Conditioning Systems. See(MAC directive) of EC F-Gas (Fluorinated Gas) Regulations also see http://www.defra.gov.uk/environment/air-atmos/fgas/sectors/mobileaircon.htm for more details.

Persons handling refrigerant must be F-gas trained and qualified as a refrigerant handler to meet the requirements of 2014 EC regulations and also company registered see Guidance notes

more information about F Gas regulations and guidance is available from Gluckman Consulting see IS6 and IS22

Commercial vehicle transport refrigeration systems may use alternative refrigerants.

Different refrigerant types and systems require different service equipment.

Moisture and the Air conditioning system

Moisture is a main enemy of the air conditioning system components because;

  • Moisture can form ice and cause refrigerant circuit components to block.
  • Moisture within the refrigerant circuit can mix with oil to form acids which corrode the air conditioner system components.
  • Moisture accumulating on the surface of the evaporator and within air vents can breed bacteria causing smells inside the vehicle ( aka Sick car syndrome)

    Moisture can enter the refrigerant system if a leak occurs allowing air ingress or if the system has been opened.

    Marginal refrigerant gas loss can occur over time. The only effective cure for a refrigerant leak is a repair or component renewal.
