• Abstract:
  The objective of the project is to analyze existing technologies used for the process of generating counts of bicycles ; and pedestrians in transportation facilities such as walk and bicycle bridges, urban bicycle routes, bicycle trails etc. ; The advantages and disadvantages of each existing technology which is being applied to counting has been ; analyzed and some commercially available products were listed. A technical description of different methods that ; were considered for vision based object recognition is also mentioned along with the reasons as to why such ; methods were overlooked for our problem. Support Vector Machines were used for classification based on a ; vocabulary of features built using interest point detectors. After finalizing the software and hardware, five sites ; were picked for filming and about 10 hours of video was acquired in all. A portion of the video data was used for ; training and the remainder was used for testing the algorithm’s accuracy. Results of counts are provided and an ; interpretation of these results is provided in this report. Upon detailed analysis the reasons for false counts and ; undercounting in some cases have been identified and current work concerns dealing with these issues. Changes are ; being made to the system to improve the accuracy with the current level of training and make the system available ; for practitioners to perform counting.
