State Highway Reliability 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.

Basis for Non-Interstate National Highway System (NHS) Reliable Person-Miles Traveled:
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.
