  1. Jerzy Wieczorek • 2nd year M.S. Student in Statistics • ITS Research: • Historical and real-time bottleneck identification • Statistics Research: • Minimum Kolmogorov-Smirnov Estimation (MSKE) with censored data Jerzy Wieczorek 1

  2. Using speed data to track historical congestion and rank bottlenecks by cost Incorporating historical information into model to predict real-time bottleneck behavior Work with Prof. Bertini, Huan Li,Rafael J. Fernández-Moctezuma Bottleneck Identification Jerzy Wieczorek 2

  3. Expanding model to use volume data Validating against ground truth from Bertini-Cassidy method Work with Prof. Bertini, Huan Li,Rafael J. Fernández-Moctezuma Bottleneck Identification Jerzy Wieczorek 3

  4. Minimum K-S Estimation θ = 72.2 θ = 96.1 Choose distribution and parameter estimates that minimize the K-S statistic (max. vertical difference in CDFs) Work with Prof. Kim Jerzy Wieczorek 4

  5. Minimum K-S Estimation Extend to censored data Evaluate in comparison with MLEs (standard) Create R library if worthwhile Work with Prof. Kim Jerzy Wieczorek 5
