摘要: |
This project proposes developing a new device that integrates two systems� namely
magnetometer classification and Bluetooth (BT) identification�for monitoring route choices per vehicle class, as well as targeting system deployment and demonstration. Overall system implementation consists of one BT identification/vehicle classification unit deployed at an Oklahoma port of entry, as well as a number of BT identification stations deployed at various locations across Oklahoma�s roadways.
Objectives: The study includes BT/class prototype design, BT-vehicle assignment algorithm development, system deployment, and accuracy analysis of detected BT vehicle assignments.
Work Plan:
B1. Highway Segmentation and Sensor Layout
B2. BT-Vehicle Assignment Algorithms and Case Studies of Assignment Uncertainties
B3. BT-Vehicle Assignment Accuracy Enhancement Methods
Anticipated Benefits: Upon a successful implementation of this proposed project, ODOT will gain significant travel information per vehicle class.
Implementation: Develop an origin/destination (O/D) and travel times (TT) measurement per vehicle class composed of BT sniffer wirelessly integrated with a magnetometer vehicle classifier. Implementation will include workshops, publications, and presentations.
Expected Deliverables:
� BT/class system design
� methods and algorithms to assign BT identifications to corresponding vehicles
� system accuracy analysis and discussion about results
� proposed methods to improve system accuracy
� O/D and TT measurements
Time Schedule: The research activities during the first project year will focus on constructing the BT/Class station and developing BT-vehicle assignment algorithms. System deployment, field study, and performance analysis will be conducted during the second project year. |
