This study is intended to evaluate the feasibility of introducing a single loop-based vehicle detector in preparation for installing the device for permanent traffic volume counts by segment. Existing AVC comprises two loop sensors and one piezo sensor which are costly for installation. Should the vehicle classifications be similar within the section, reliable traffic data collection would be possible using a single-loop alone, which needs to be evaluated. For this, traffic volume and vehicle classifications collected by two AVCs within a section were analyzed with cost-benefit analysis for analyzing the feasibility of applying a single loop-based vehicle detector . As a result of comparing and analyzing the vehicle type ratio in 36 sections where two AVCs are installed respectively, 90% of the total showed the error rate 15% or less, and according to T-test and correlation analysis result, no statistical significance between two locations in vehicle type ratio was found. According to economical feasibility analysis, B/C 12.19, NPV 474.0 bil and IRR 196%. Thus, collection of vehicle type ratio from one AVC in the section and installation of a singl loop-based vehicle detector in a single section would produce more efficient and cost effective count. Further study on cost and benefit through more intensive statistical analysis would be necessary in the coming days.
