@article{(Open Science Index):https://publications.waset.org/pdf/3132, title = {The Optimization of an Intelligent Traffic Congestion Level Classification from Motorists- Judgments on Vehicle's Moving Patterns}, author = {Thammasak Thianniwet and Satidchoke Phosaard and Wasan Pattara-Atikom}, country = {}, institution = {}, abstract = {We proposed a technique to identify road traffic congestion levels from velocity of mobile sensors with high accuracy and consistent with motorists- judgments. The data collection utilized a GPS device, a webcam, and an opinion survey. Human perceptions were used to rate the traffic congestion levels into three levels: light, heavy, and jam. Then the ratings and velocity were fed into a decision tree learning model (J48). We successfully extracted vehicle movement patterns to feed into the learning model using a sliding windows technique. The parameters capturing the vehicle moving patterns and the windows size were heuristically optimized. The model achieved accuracy as high as 99.68%. By implementing the model on the existing traffic report systems, the reports will cover comprehensive areas. The proposed method can be applied to any parts of the world.}, journal = {International Journal of Transport and Vehicle Engineering}, volume = {5}, number = {5}, year = {2011}, pages = {487 - 492}, ee = {https://publications.waset.org/pdf/3132}, url = {https://publications.waset.org/vol/53}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 53, 2011}, }
