This document provides guidance on developing an initial lifecycle planning (LCP) process that satisfies the requirements in the Asset Management Rule and leads to the identification of an effective investment strategy for managing transportation assets. As agencies mature in their use of an LCP process it is
anticipated that they will be able to employ more sophisticated analysis tools and techniques.

Montana's long range plan was first adopted in 1995, and most recently updated in 2017. It details the state's transportation policy direction a 20-year horizon and guides decision-making. The long range plan collects information about the transportation assets in addition to surveys and public comments to address the current and future transportation needs.

The objective of this research, NCHRP 13-04, was to develop a Guide for Optimal Replacement Cycles of Highway Operations Equipment. The guide included processes and tools for consideration in making decisions regarding the optimal replacement cycles of on- and off-road highway operations equipment used by state highway agencies.
The study’s report, Research Report 879: Optimal Replacement Cycles of Highway Operations Equipment, acts as a handbook on equipment replacement concepts and an instruction manual for making cost-effective replacement decisions. The research report presents a process for determining replacement needs for highway operations equipment, identifying candidate equipment units for replacement, and preparing an annual equipment replacement program. The products include a guidance document and an Excel-based replacement optimization tool to support the equipment replacement process and facilitate its implementation.

The objective of this research, NCHRP Project 14-20A Consequences of Delayed Maintenance of Highway Assets, was to develop processes for quantifying the consequences of the delayed application of maintenance treatments on highway pavements, bridges, and other physical assets. The research expressed consequences in terms of performance indicators (e.g., distress and level of service), costs to owners and road users, and other relevant factors and defined delayed maintenance applications by (1) the inability to meet the agency-defined application schedule or (2) the available budget relative to an unconstrained budget (i.e., availability of the funds required to perform all needed maintenance). 

The Caltrans Division of Maintenance continually seeks improved methods and equipment to increase efficiency and worker safety, which in turn supports Caltrans’ mission and goals. The sealing of highway pavement cracks and longitudinal joints has been identified as an area possibly in need of enhancement. Unsealed pavement cracks, either in the form of random stress failure cracking or linear joints, accelerate highway pavement deterioration due to water and debris penetrating the structural section, thereby undermining pavement integrity. According to Federal Highway Administration (FHWA) study results, a properly installed, heated application of rubberized asphalt joint seal should remain effective an average of five years. All the major sealant manufacturers recommend the crack or joint be dry and free of all dirt, dust, debris, and vegetation prior to applying their rubberized asphalt sealants for optimum performance. Failure to properly clean a pavement crack or joint may result in the seal failing as soon as one thermal cycle, i.e. in less than one year. Unfortunately, conventional highway pavement crack cleaning techniques are innately labor-intensive and require workers to be on foot and exposed to traffic for prolonged periods of time, which often downgrades crack preparation tasks to low priority in a sealing operation. Caltrans Maintenance is interested in a broad look at equipment used by other state transportation agencies, as well as any recent innovations in crack cleaning technologies that may be utilized by Caltrans Maintenance to enhance highway sealing operations and thereby improve pavement maintainability statewide.

This summary and timeline, developed by North Jersey Transportation Planning Authority (NJTPA), presents information on the implementation of MAP-21/FAST Act performance measures and performance-based planning. Page 1 summarizes key reporting requirements by performance area. Page 2 includes a detailed reporting timeline. The summary is in draft form and was prepared by NJTPA staff to highlight reporting requirements of NJTPA its partner agencies.

TRB's National Cooperative Highway Research Program (NCHRP) Research Report 854: Guide for Identifying, Classifying, Evaluating, and Mitigating Truck Freight Bottlenecks provides transportation agencies state-of-the-practice information on truck freight bottlenecks using truck probe data rather than traditional travel demand models. The report embraces a broad definition of truck freight bottlenecks as any condition that acts as an impediment to efficient truck travel, whether the bottleneck is caused by infrastructure shortcomings, regulations, weather, or special events. The comprehensive classification of truck freight bottleneck types described in this report provides a standard approach for state departments of transportation, metropolitan planning organizations, and other practitioners to define truck freight bottlenecks and quantify their impacts.

These outreach materials, published by the FTA on August 25, 2017, include information associated with the TAM rule, such as:
- Fact Sheets
- TAMNews, including upcoming initiatives and webinars
- Training, including information from the TSI, NTI, and NHI
- Presentations, recorded materials, and transcripts

The TAM FAQs page includes further explanation of ULBs and performance targets, implications of having non-rail fixed guideway and shared use facilities, and requirements for tribal transportation providers.

This issue of TAMNews discusses new resources added to the website including new FAQs as well as an article on MTA's efforts to publicly document improvements using a subway 'report card'.

This guide produced by the Tennessee Department of Transportation (TDOT) is a documentation of a particular transportation performance measure (Number of Fatalities – 5 Year Rolling Average), and its related rules and requirements, including: baseline, scope, audience, team members, data sources, data analysis methodology, target selection and calculation, and target monitoring.

The Alabama DOT long-range plan outlines the state's transportation needs, finances and policies to 2040. It is a multimodal plan, evaluating not only the roads and bridges, but also the transit, freight, bicycle and pedestrian facilities, rail, aviation and waterways. The plan provides a macro-level assessment of the current and estimated future travel conditions, and then focuses on Alabama's policies and strategies for achieving their agency goals.
