Abstract

The purpose of this study was to identify and evaluate treatments and strategies to mitigate traffic congestion on the I-10 Mississippi River Bridge in Baton Rouge, LA. Based on VISSIM simulation results, combination of supply- and demand-oriented measures will be required. Rehabilitation of the old bridge on US-190 and the existing US-190/US-61 corridor, overall demand management of I-10 EB traffic, reduction in percent trucks traveling eastbound on I-10 during the A.M. peak, and ramp metering at the on-ramp west of the I-10 Mississippi River Bridge appear to be feasible and effective solutions.

Highlights

I-10 is the most heavily traveled coast-to-coast interstate in the U.S It is a national freight corridor of significant importance to the economy
This study focused on evaluating several supply-oriented and demand-oriented solutions to mitigate the congestion problem at the I-10 Mississippi River Bridge (MRB) site
Development (LADOTD), the Streetlytics database developed by CitiLabs, the National Performance Management Research Data Set (NPMRDS) maintained by FHWA, and traffic signal timing data (TSTD) from the City of Baton Rouge and LADOTD

Summary

Introduction

I-10 is the most heavily traveled coast-to-coast interstate in the U.S It is a national freight corridor of significant importance to the economy. The portion of I10 through Baton Rouge, LA was constructed in the 1960’s as a four-lane freeway (two lanes per direction). Traffic demand in Baton Rouge has been growing steadily and currently exceeds the capacity of the corridor during the morning and afternoon peak periods. Severe traffic congestion is a recurring problem along the segment of I-10 from Louisiana Highway 415 (LA 415) across the Mississippi River Bridge (MRB) to the I-10/I-12 merge. Capacity improvements to I-10 and I-12 in the eastern suburbs helped deliver more traffic to the core of the urban area, compounding the traffic congestion on I-10 and the MRB.
