摘要

This paper attempts to gain insights into drivers' speeding behavior upon passing speedenforcement zone. A total of 630 drivers in Thailand were interviewed using a self-reportedquestionnaire, and they were classified into four types of the Corbett's drivertypology: conformers (i.e., those who usually comply with speed limits), deterred drivers (i.e.,those who reduce speed all along speed enforcement zone), manipulator (i.e., those who slowdown and accelerate after passing speed enforcement zone), and defiers (i.e., those who usuallyexceed legal speed limit irrespective of the presence of speed enforcement zone. The statisticaldata tests showed that, manipulators and defiers tend to be those who received a speeding penaltyduring the past year. It was also found that they are likely to be wealthy and experienced drivers,but have personal attitude against the speed enforcement policy.
