State Highway Infrastructure Report - New Jersey

In the line graphs below, FHWA has shifted the "Year" label in the x-axis back by one year, from Data Reporting Year to Data Collection Year. More information

The information displayed is provided by the State in their 2018 Baseline Performance Period Report (BPP) and has not been edited by FHWA. Any questions about individual State reports should be directed to the respective State DOT

Please note: FHWA posted baseline data from State BPP reports to help bring context to their performance targets. This data may result in some discrepancies among published DOT performance data due to data sources and reporting years used when establishing the performance targets.

  The information from the 2016 HPMS supplemental report that was provided to NJDOT to approximate the baseline for this measure in order to develop targets by May of 2018 indicated that the baseline was 61.25%.NJDOT used its pavement management system and its own measures, metrics and budget information to predict performance on the State Highway System, where it has significant experience with performance management and forecasting. A correlation analysis was developed and applied to the State Highway System performance to try to-predict corresponding performance on the NHS using the Federal measures and metrics. The results of this correlation analysis showed a gradually declining trend on both the Interstate and non-Interstate NHS pavements at the current funding level. Although not available to NJDOT at the time the targets were set, the results of the 2017 HPMS data submission indicated that performance for this measure had dropped to 55% setting a significant declining trend. Since comprehensive quantitative data regarding current and future investment levels on the NHS by other owners is not readily available, a survey was sent to all owners requesting information on past and future expenditures on NHS routes as well as qualitative information regarding future funding and pavement performance. This information was used to help validate the results of the correlation analysis.Since NJDOT has no experience evaluating and managing the NHS as a whole, no experience with the Federal pavement measures and metrics, only an estimated baseline condition for the NHS, a declining performance history for the NHS by the newly established metrics, as well as no specific budgetary or treatment type, cost and trigger information for the other 83 owners of the NHS, the Department recommends adopting conservative but realistic targets for this initial performance period with the understanding the they can be modified at the mid-period review if appropriate.

  The information from the 2016 HPMS supplemental report card that was provided to NJDOT to approximate the baseline for this measure in order to develop targets by May of 2018 indicated that the baseline was 1.01%. NJDOT then used its pavement management system and its own measures, metrics and budget information to predict performance on the State Highway System, where it has significant experience with performance management and forecasting. A correlation analysis was developed and applied to the State Highway System performance to try to-predict corresponding performance on the NHS using the Federal measures and metrics. The results of this correlation analysis showed a gradually declining trend on both the Interstate and non-Interstate NHS pavements at the current funding level. Although not available to NJDOT at the time the targets were set, the results of the 2017 HPMS data submission indicated that the percentage of lane miles in poor condition had increased to 1.4% corroborating a declining trend.

  For the initial target setting process, we set initial targets based on the analysis we have performed on the State Maintained inventory, assuming that NHS bridges owned by others will remain stable, and then adjusted the targets prior to the letter to the FHWA being sent once we had sufficient data developed to look across (almost) all NHS bridge owners and check overall trends.

  The percentage good trends for Statewide NHS bridges is level while Statewide NBIS bridges trend downward. Since CY2012, we have been losing 250,000 sq. ft. per year on average from the GOOD category in the State Maintained NBIS inventory. This loss is sufficiently consistent that we do not expect it to change over the next few years.

  As the Department had never previously measured the Percent GOOD, we had not made provision for improving this statistic. Within the 4 year time frame for these targets, there is not likely to be enough time to turn this trend around. However, moving forward, as we implement AASHTOWare’s BrM as our main data analysis tool, we will be able to make projections of changes to the population of bridges rated GOOD, based on different possible longer term program makeups.

  For the initial target setting we have set targets based on the analysis we have performed on State Maintained bridges, including determining the likely delivery dates of projects in the pipeline as well as near-term uncommitted bridge funding, as well as the trends seen in the condition of the bridges for the other bridge owners.

  The State Maintained bridge population is responsible for over 90% of the total POOR statewide bridges. Therefore, if we want to reduce the POOR square footage statewide, we must reduce the State Maintained POOR inventory. Although the upcoming projects do address some of that inventory, it is not sufficient to make a significant difference, especially as the average NHS bridge is almost 54 years old. This aging population results in additional inventory becoming poor every year. Based on available information, we have to assume that the State Maintained POOR percentage will remain relatively level over the next several years.

  We made the assumption that the performance of all other bridge owners was going to remain essentially level. The NJTA is responsible for 2/3 of the remaining POOR condition bridges. They have recently completed a major upgrade to their system, and have increased funding for bridge maintenance. Therefore, it is reasonable to predict that their inventory will be stable over the four year time frame. County bridge owners will be benefiting from the recent increasing in bridge funding for local aid projects from $25 million to $44+ million per year. The formula for the distribution of this funding puts an emphasis on POOR bridges. Therefore, the most significant variable at present is the State Maintained inventory. We therefore have set level targets for POOR bridges for the next 4 years.
