This project uses statistical methods to analyze traffic congestion of the upper Mississippi and the Illinois Rivers, in particular, locks 18, 20, 21, 22, 24, and 25 on the upper Mississippi and the Lagrange and Peoria locks on the Illinois River. The main purpose of this project is identifying and evaluating non-structural alternatives (those not requiring construction, but rather procedural or policy changes, for instance, congestion fee, excess lockage time charges, helper boats, switch boats, deck winches, and moorings) that might be employed to offer nearby congestion relief. The first objective of this study was to carry out statistical analysis on locking activity at each lock site for each locked vessel to gain insight on forces that affect congestion and to examine the possibilities for congestion mitigation through nonstructural alternatives. The second objective was to measure the effect of inland waterway congestion on barge transportation rates as well as other costs associated with the predetermined lock chokepoints and develop methodology increasingly appropriate for such measures. |
