Introduction

NCHRP Research Project 23-07, Guide to Effective Methods for Setting Transportation Performance Targets, presents several approaches for setting performance targets to support a TPM framework. It focuses on target setting for the national measures that are required under federal TPM requirements, including:

• Safety measures: Number of fatalities, rate of fatalities, number of serious injuries, rate of serious injuries, number of nonmotorized fatalities and nonmotorized serious injuries.
• Infrastructure condition measures: Percentage of the Interstate system pavements in good and poor condition, percentage of the non-Interstate NHS pavements in good and poor condition, and percentage of the NHS bridges in good and poor condition.
• Reliability (travel time and freight) measures: Percentage of person miles traveled on the Interstate and Non-Interstate NHS that is reliable and truck travel time reliability index.
• Congestion measures: Annual hours of peak hour excessive delay per capita and percentage of non-single-occupancy vehicle travel.
• Target setting for nonrequired measures, such as accessibility, greenhouse gas emissions, active transportation, transit ridership, and customer satisfaction are included in the final section of the guide.
