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.
