Baton Rouge, LA Urbanized Area Congestion Report
In the line graphs below, FHWA uses Data Collection Year instead of Data Reporting Year to represent snapshot condition/performance at the time the data was collected. More information
The Baton Rouge, LA Urbanized Area covers parts of Louisiana. Targets are agreed upon by several transportation agencies and apply to the entire area.

(Louisiana) The 2-year and 4-year targets for the 2022-2025 report period were established from the historical data. The historical PHED data was collected from the NPMRDS data set. The yearly PHED was calculated by dividing the total PHED into all TMC segments in the network by the total population. The historical PHED data was available from 2017 to 2021. Due to the Covid pandemic, 2020 and 2021 show unusual traffic conditions. So, 2020 and 2021 PHED data was disregarded for estimating targets. Different statistical forecasting methods were applied to evaluate trends and estimate the targets for the capital region. The most feasible and conservation target was selected as the 2023 and 2025 targets. The anticipated targets are expected to reduce roadway delays. Anticipated targets are higher compared to the baseline year 2019. If we look at the 2017 (PHED=24.3) and 2018 (PHED=26) values, the 2019 (PHED=20.7) value is significantly low. At this point, the 2-year target (PHED=23.7) is lower than both the 2017 and 2018 values, and the 4-year target (PHED=27.2) is not significantly higher than the 2017 and 2018 values. If the 2022-2025 targets are achieved, the capital region will be able to significantly decrease the roadways' delay. The historical analysis shows a decrease in delay in the capital region. The historic PHED value from 2017 to 2021 shows a downward trend. In addition, during this time range, the annual average reduction of PHED value is 0.82 percent. In 2019, ten projects were authorized that involved $47.76 million of investment. Before the investment, the PHED value was 26, and after the investment, the value came down to 14.4, which implies the investment contributed to saving 11.6 hours of delay. In other words, per million-dollar investment reduces 0.24 hours or 14.4 minutes of delay. In 2020, $61.186 million was invested. The investment could not decrease the delay hours but limited the increase of the delay to 5.4 hours. More specifically, per million-dollar investment controlled the increase of delay to 5.4 minutes. The 2019-2022 TIP included 45 projects related to PHED reduction. The 2023-2026 TIP has 93-projects that are directly or indirectly related to reducing congestion. From the historical trend and PHED reduction analysis, TIP projects are expected to reduce PHED in the capital region significantly. In this way, the established targets will support the goal of the long-range transportation plan of the capital region.

(Louisiana) The 2-year and 4-year target for the 2022-2025 performance period was established from the historical data. The historical SOV data was collected from the American Community Survey’s 5-year estimate. From the SOV data, non-SOV was estimated by subtracting SUV value from 100 (one hundred). After that, different statistical forecasting method was applied to find the most feasible and conservative target.
The 2-year and 4-year targets show lower values compared to the baseline year 2019. The 2-year target is decreased by 1.78 percent, and the 4-year target is decreased by 3.55 percent compared to 2019. The capital region is working to limit the decreasing trend of non-SOV vehicles. Though 2010 to 2020 historical data show a decreasing trend, the recent data (2016-2020) show an increasing trend of non-SOV. From 2010- 2020, the capital region was able to limit the decreasing trend of non-SOV by 0.82 percent annually, and from 2016-2020 CRPC was able to increase non-SOV by 0.99 percent annually.
In 2019, ten projects were authorized related to non-SOV. As a benefit of these projects, CRPC was able to increase non-SOV by 0.4 percent. The current TIP has 45 projects, and the 2023-2027 TIP has 93 projects. These projects are expected to increase the non-SOV value significantly. From the historical data trend and TIP projects, it is expected that the capital region will be able to increase the non-SOV and achieve the goal of the long-range transportation plan.
