  • Abstract:
    Vehicle detection technologies have been rapidly evolved over the past decade due to the advancement  ; of sensors and wireless communication technologies and the increasing deployment of traffic‐responsive and  ; adaptive traffic control systems, which heavily rely on robust vehicle detection.  Given a variety of vehicle  ; detection  technologies  available,  each  has  its  advantages  and  disadvantages  and  may  or  may  not  be  ; appropriate for specific situations or  contexts. This research study  is  conducted to  identify the  contexts  ; appropriate for different detection technologies.  High‐resolution data were collected in the field from three  ; test sites selected in Georgia.  Data mining techniques were employed to identify potential factors underlying  ; variation in detection errors of different technologies and quantify their respective effects. The quantified  ; effects were then used to construct technical performance measures in terms of accuracy and reliability,  ; referred to as technical performance criteria.   An agency survey was also conducted in Georgia to assess  ; nontechnical performance criteria, such as life cycle cost and ease of installation and maintenance. Both  ; technical and nontechnical performance criteria were considered in evaluating vehicle detection technologies  ; through a multicriteria framework.   Finally, practical constraints frequently encountered in Georgia were  ; considered as part of respective application contexts.  Based on the results and findings, specific guidelines  ; were developed to promote consistency in application of various detection technologies and to enhance  ; efficiency and safety in traffic signal operations in Georgia.
