| Abstract: | Using an improved analysis, this paper provides new evidence regarding the influence of vehicle attributes on the estimation of vehicular speed by an observer. An analysis of speeding records indicates that brightly colored vehicles systematically receive citations for relatively lower speeds. Findings also indicate that trucks were cited for significantly higher speeds than were cars. The findings clarify earlier conflicts in the literature as to whether vehicular characteristics give an impression of higher speed. As an additional topic of investigation, evidence is provided that outsiders, those not living in the jurisdiction, received citations for significantly lower speeds. |
