Abstract |
The development, validation, and testing of a headlight measurement system (HMS) are described. The HMS hardware and the software developed for the system are described. The field study consisted of collecting data at six key visual points in the driving task. A complete, detailed manual developed on the setup and use of the HMS is discussed. The equipment setup and operating instructions, the calibration procedure, and recommendations for future system modification to improve the HMS are discussed. It was concluded that although more expensive sensors, in the $6,000 to $10,000 range, could be custom made and incorporated into a more sophisticated (but costly) system, the system developed proved to be adequate for the main purpose of determining distribution of light output of the current fleet of highway vehicles at any set of up to seven desired points quickly, easily, and with reasonable accuracy with relatively inexpensive, off-the-shelf hardware. Two companion manuals were also developed during the study: "Light Measurement System Manual" and "Installation and Operation Manual". Language: en |
