Asset Management, System Performance

As new technologies are developed in the field of transportation, agencies have the opportunity to collect more data than ever before. In this report, agencies are introduced to an eight step framework for managing this new big data and incorporating it into asset management. The eight steps start with gaining an understanding of big data, then walk through the process for piloting a big data test environment. The steps end with demonstrating the value of the data to other business units and executives and set up a formal storage environment. Supporting this report are several additional tools, including a data management capability self-assessment, a catalog tool, and more information on data governance.

System Performance

This guide helps agencies to incorporate equity into their transportation plans through a five-step framework for conducting equity analyses. The five steps are: identifying populations for analysis, identifying needs and concerns, measure impacts of proposed agency activity, determine if impacts are disparate or have adverse effects, and develop strategies to avoid and mitigate inequities. Though intended for Metropolitan Planning Organizations (MPOs), this guide is also applicable to transit agencies, state DOTs, and other transportation agencies that seek to address equity in their plans, programs, and policies.

System Performance

Public-private partnerships (P3) offer transportation agencies a method for designing, building, operating, and maintaining their assets without having to wait for government funding. To ensure contract compliance and performance, agencies use a variety of different metrics to monitor their P3 contracts. Metrics usually fall into two main categories: quantifying asset performance and project implementation. This report presents such metrics used by DOTs. Data was sourced from a survey of 26 DOTs and interviews with DOT personnel on six P3 projects.

System Performance

Reliability is an increasingly important measure for transit performance as transit must compete with other mobility service providers. In this guide, public transit agencies and and other stakeholders are instructed on the value of measuring reliability and how to address the reliability issues for several different environments. The guide examples focus on fixed-route bus service, as it is the most common mode of transit in the US and globally, but the methodology may be applied to other modes as well. It presents the three key components of reliability: short wait times, on-time arrivals, and consistent travel times. Three perspectives are also addressed in the guide; these are customer, agency, and operator perspectives.

Transportation agencies nationwide must comply with provisions in the Americans with Disabilities Act (ADA). To assess ADA compliance, agencies need to develop a comprehensive inventory of pedestrian facilities, identify non-compliant locations, and develop a program for remedial repairs in order to bring facilities into compliance. The purpose of NCHRP Project 20- 07, Task 249, Asset Management Approaches to ADA Compliance, was to gather information and develop a synthesis of practices, including best practices, on the various approaches transportation agencies use to address ADA compliance issues. The synthesis covered three main topics: asset data inventory, asset condition assessment, and programming of asset improvements. To make the project manageable, the focus was on pedestrian infrastructure on the public right-of-way, including elements such as sidewalks, curb ramps, pedestrian crossings, and obstructions. The analysis did not include buildings, facilities, or transit infrastructure. The synthesis also included the compilation of an extensive listing of asset inventory and condition data elements. The listing is intended as a preliminary menu that agencies could use as a foundation for the development of inventory programs that meet individual agency needs.

Several State Departments of Transportation (DOTs) are considering revising their right-of-way business practices with the goal of simplifying and streamlining processes. Current right-of-way practice and procedure manuals are the products of 40 years of statutes, case law, regulations, management styles and best practices. The procedural manuals have chapters to cover elements such as: a) appraisal; b) appraisal review; c) relocation planning and assistance; d) relocation eligibility and supplemental payments; e) nonresidential relocations; f) acquisition and negotiations; g) legal settlements; h) eminent domain; i) titles and closing; j) property management; k) leasing; l) sale of excess property; m) mapping and geographic information systems (GIS); n) encroachments; o) contracting for services; and p) administrative costs. Procedures and guidelines are often an accumulation of historical practice or those adopted from other agencies. State procedures vary widely because of differences in State laws. Local agencies are required to follow State DOT procedural manuals when they use State or Federal funding. Questions arise as new staff try to understand the reason or underlying basis for requirements. Contractors and consultants face a wide array of requirements and forms among the various States. This research is in support of the AASHTO Highway Subcommittee Right-of-Way and Utility strategic plan to provide leadership and support to member agency right-of-way staff. This research will provide new direction and lead to immediate cost savings by reducing the hours required to accomplish certain functions. This research will result in streamlined business practices that are easier to maintain, cost effective and result in delivery of projects sooner. Research is needed to provide information to State DOTs and local agencies to rationally evaluate current right-of-way procedures and business practices; to determine what function is served by each procedure; to determine the need for each procedure, i.e. statute or practice; to document the benefits and operational logic for continuing a procedure, modifying, or eliminating it, evaluate the cost of maintaining current procedures and to quantify the benefits from them. This includes, but is not limited to, the current cost of agents, training new agents and administrative costs on a parcel or tract basis. Determine what processes are essential to providing a consistent product and comply with statutory requirements, such as the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (Uniform Act), as well as the most common elements of State eminent domain laws, identify institutional, political, and economic barriers to the adoption of procedures that will be easier to maintain for the next 20 years, and examine and compare several common types of existing FHWA approved right-of-way manuals used by State DOTs and local agencies and common State regulations. Agencies will be contacted and staff will be interviewed to ascertain what are the origins, purpose and authorities for the existing procedures; what criteria and procedures are needed, as a minimum, to protect owner and tenant rights; what procedures would work if the agency could start anew; how and/or whether procedures might be modified for local agency use, i.e., a stand alone manual for local agencies; what are the issues in administering procedures that need to be addressed to assure consistent application; and what are the institutional, political, and economic barriers to implementation? A major objective of the research will be to develop a rationale or basis for a new or modified approach. This will include an objective analysis of all key elements mentioned above, i.e., appraisal, appraisal review, relocation, etc. This research would culminate by analyzing the typical right-of-way business model for the four major elements of appraisal, acquisition, relocation, and property management, and developing a revised model that is less costly to maintain. It would outline a sample procedural manual with forms that could be used to administer a simplified and cost-effective right-of-way program that is responsive to national statutes and the Uniform Act. The resulting business model would be accompanied by a cost/benefit analysis and recommended roll-out implementation plan that could be readily adopted and applied by State DOTs and local agencies for national consistency. One of the initial goals of the Uniform Act was to create a fair and consistent process for the acquisition of real property by public agencies. This research would help us assure the continued uniformity of the process. This research will be a direct follow-on to the 2008 International Scan for ROW and Utilities called "Integrating & Streamlining Right of Way and Utility Processes with Planning, Environment, and Design." Ideas and strategies derived from the 2008 International Scan will feed directly into revised business practices. State DOTs who undertake pilot projects in 2009 will be able to use lessons learned and provide input to this research effort. The timing is beneficial for all parties in that this research product will bring about full implementation of the 2008 streamlining strategies. This research will provide new direction and lead to immediate cost savings by reducing the hours required to accomplish certain functions. This research will result in streamlined business practices that are easier to maintain, cost effective and result in delivery of projects sooner. The effort devoted to training new right-of-way agents, who may or may not stay with the agency, is becoming cost prohibitive and is time consuming. It is anticipated that there will be many institutional barriers to overcome. Many right-of-way agents have adapted to the current procedures and will be resistant to change. State DOT legal staff also may resist changes, thinking that revised procedures may affect property owner rights. In order to address these barriers, the final research report should contain an outline of a revised procedural manual that would be sufficient to meet Federal regulations and laws, allowing each State to augment this information with specifics to address that particular State's laws.

Asset Management, Bridge

This report describes how risk management and data management may be used by transportation agencies to support management target-setting for performance-based resource allocation. As the final product of a second phase of NCHRP Project 08-70, Target-Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies, this report supplements NCHRP Report 666, "Target-Setting Methods and Data Management to Support Performance-Based Resource Allocation by Transportation Agencies: Volume I: Research, Volume II: Guide for Target-Setting and Data Management," published in 2010. Transportation agencies at all levels of government are embracing performance measurement to improve agency efficiency and accountability. Setting performance targets generally entails balancing competing objectives and dealing with political implications in a context of uncertainties about economic conditions, fiscal constraints, climate conditions, customer demands, and more. Good data on the transportation system and its performance provides the information managers need to set targets, but good management depends on clear understanding of the risks that future conditions will differ significantly from what today's best information suggests. Performance targets and consequent resource-allocation decisions established with such understanding are more likely to ensure that the agency and the transportation system perform well. This report presents advice and illustrative case studies, in the form of primers, on using risk management and data management practices in support of performance-based resource allocation, and specifically performance-target setting. The information will be useful to senior agency managers seeking to develop and improve their performance-management practices.

Transportation agencies are developing procedures and guidelines for managing the quality of pavement data collected to ensure the data meet the needs of the pavement management process. This study reviews the quality management practices being employed by public highway agencies for automated, semi-automated, and manual pavement data collection and delivery. Information was gathered through literature review, surveys of U.S. state and Canadian province public agencies and private contractors, and selected interviews.

This fifteenth volume of NCHRP Report 525: "Surface Transportation Security" is a guide referred to as CAPTA, which stands for Costing Asset Protection: An All Hazards Guide for Transportation Agencies. CAPTA supports mainstreaming an integrated, high-level, all-hazards, National Incident Management System (NIMS)-responsive, multimodal, consequence-driven risk management process into transportation agency programs and activities by providing a convenient and robust planning tool for top-down estimation of both capital and operating budget implications of measures intended to reduce risks to locally acceptable levels. CAPTA is intended for use by senior managers whose jurisdiction extends over multiple modes of transportation, multiple asset classes, and many individual assets. The CAPTA methodology provides a means for moving across transportation assets to address system vulnerabilities that could result in significant losses given the threats and hazards of greatest concern. This guide was reviewed by many state and local agencies and was pilot tested by the Maryland Department of Transportation (DOT), the Massachusetts Bay Transportation Authority (MBTA), and the Virginia DOT.

Asset Management

This report updates the findings contained in NCHRP Report 522, "A Review of DOT Compliance with GASB 34 Requirements." NCHRP Report 522 provided a comprehensive look at approaches taken by AASHTO member departments to comply with the requirements of Governmental Accounting Standards Board (GASB) Statement No. 34. NCHRP Report 608 provides a recommended practices guide that identifies effective methodologies that integrate infrastructure inventory, condition assessments, minimum acceptable condition levels, and funding decisions with GASB 34 reporting requirements and assesses the operational and financial impacts of reporting under GASB 34. This report will be helpful to professionals who work with state departments of transportation and local governments in the areas of finance, auditing, asset management, and policymaking.

Asset Management, Pavement

This report presents models for estimating the effects of pavement condition on vehicle operating costs. These models address fuel consumption, tire wear, and repair and maintenance costs and are presented as computational software on the accompanying CD-ROM, CRP-CD-111, to facilitate use. The material contained in the report should be of immediate interest to state pavement, construction, and maintenance engineers; vehicle fleet managers; and those involved in pavement investment decision processes and financial aspects of highway transportation.

Asset Management, Bridge, Pavement

This report presents a logic framework for allocating limited highway asset preservation funds among competing demands to achieve high levels of system performance. The report also presents a spreadsheet-based computational tool that implements the framework. The tool uses linear programming optimization to allocate resources across asset classes or geographic regions, subject to constraints that typically must be considered in such decisionmaking, to achieve target asset performance or condition levels. Prototypical application scenarios and case-study examples illustrate how transportation agency staff may use the framework to assist resource allocation decisionmaking.

The objectives of this study were to gather information on asset management practices in the United States and overseas, develop a framework for transportation asset management, and apply this framework to produce the "Transportation Asset Management Guide." Phase I of the study encompassed information gathering, framework development, and recommendation of a research program. The products of Phase I have been issued in three separate volumes. This report constitutes the second volume, addressing a comprehensive transportation asset management framework. This framework defines transportation asset management within the context of this study, and establishes its basic concepts and elements. Its management approach is built on the idea that an agency's processes for resource allocation and utilization are at the core of asset management. Based on this concept, the report builds a framework for agency self-evaluation of its current and desired practices. This framework identifies key characteristics and criteria of transportation asset management in four basic areas relating to resource allocation and utilization: policy goals and objectives, planning and programming, program delivery, and information and analysis. State-of-the-art practices illustrate each of these characteristics and criteria to provide benchmarks by which agencies may establish targets for incremental improvement and gauge progress toward these targets. The report also discusses strategies for updating legacy management systems and data to better support asset management, and examines the relationship between transportation asset management and recently adopted standards for financial reporting of transportation infrastructure assets.
