This document serves as Volume I in the Traffic Analysis Toolbox.

Traffic Analysis Toolbox Volume II: Decision Support Methodology for Selecting Traffic Analysis Tools

The purpose of this Decision Support Methodology for Selecting Traffic Analysis Tools is to provide an overview of the role of traffic analysis tools in transportation analysis and to present a detailed methodology for selecting the appropriate tool for the job at hand. The report describes the selection process including selection criteria and worksheets that can be used in applying the selection process.

Traffic Analysis Toolbox Volume III: Guidelines for Applying Traffic Microsimulation Modeling Software

The purpose of the Guidelines for Applying Traffic Microsimulation Modeling Software is to provide a recommended process for using traffic simulation software in transportation analyses. The guidelines provide the reader with a seven-step process that begins with project scope and ends with the final project report. The process is generic, in that it is independent of the specific software tool used in the analysis. In fact, the first step in the process involves picking the appropriate tool for the job at hand. It is hoped that these guidelines will assist the transportation community in creating a more consistent process in the use of traffic simulation software.

Traffic Analysis Toolbox Volume IV: Guidelines for Applying CORSIM Microsimulation Modeling Software

The purpose of the Guidelines for Applying CORSIM Microsimulation Modeling Software is to provide more specific guidance for using CORridor SIMulation (CORSIM) traffic simulation software to conduct a transportation analysis using the process recommended by Volume III: Guidelines for Applying Traffic Microsimulation Modeling Software. CORSIM is the core simulation and modeling component of the Traffic Software Integrated System (TSIS) tool suite. The guidelines provide the reader with a seven-step process that begins with project scope and ends with the final project report. The process is specific to using CORSIM and TSIS. It is hoped that this document will assist the transportation community in creating a more consistent process in the use of CORSIM traffic simulation software.

Traffic Analysis Toolbox Volume IX: Work Zone Modeling and Simulation - A Guide for Analysts

This document is the second volume in the FHWA Traffic Analysis Toolbox: Work Zone Analysis series. Whereas the first volume provides guidance to decision-makers at agencies and jurisdictions considering the role of analytical tools in work zone planning and management, this volume provides specific guidance to the analyst, researcher, or manager in charge of conducting a specific work zone analysis project or who has been charged with developing an overall work zone modeling program or approach. This volume includes numerous case study examples, discussion and analysis designed to provide the prospective work zone analyst with information pertaining to the selection of a transportation modeling approach (including the identification of opportunities for use, managing technical risk and examples) as well as specific project applications (including constructability, scheduling and transportation management plan design and evaluation).

Traffic Analysis Toolbox Volume V: Traffic Analysis Tools Case Studies - Benefits and Application

This document serves as the final installment of the Traffic Analysis Toolbox, but serves as a document that can be used with decision makers to support the transportation professional. Other volumes currently in the toolbox include: Volume I: Traffic Analysis Tools Primer, Volume II: Decision Support Methodology for Selecting Traffic Analysis Tools and Volume III: Guidelines for Applying Traffic Microsimulation Modeling Software.

Traffic Analysis Toolbox Volume VI: Definition, Interpretation, and Calculation of Traffic Analysis Tools Measures of Effectiveness

The purpose of the Definition, Interpretation, and Calculations of Traffic Analysis Tools Measures of Effectiveness document is to provide transportation professionals with an understanding of some of the most commonly used measures of effectiveness (MOEs) generated by traffic simulation and analytical tools, and to provide guidance on the calculation of the MOEs in some of the common analysis tools. It is hoped that this document will assist the transportation community in creating a more consistent process in the interpretation of MOEs from various analysis tools.

Traffic Analysis Toolbox Volume VII: Predicting Performance with Traffic Analysis Tools

This document provides insights into the common pitfalls and challenges associated with use of traffic analysis tools for predicting future performance of a transportation facility. It provides five in-depth case studies that demonstrate common ways to ensure appropriate results when using an microsimulation tool, and also includes “how to” material that allows users to address common challenges associated with microsimulation analysis.

Traffic Analysis Toolbox Volume VIII: Work Zone Modeling and Simulation - A Guide for Decision-Makers

This document is intended to provide guidance to decision-makers at agencies and jurisdictions considering the role of analytical tools in work zone planning and management. It is often unclear what kind of analytical approach may be of most value, particularly in light of complex data requirements and staff training. The decision to create an analytical capability to support decision making can be a significant investment, and deserves careful consideration. In the end, work zone analysis should never be used to make key decisions but instead developed as a trusted resource for understanding the potential mobility impacts and using this information to inform key decisions.

Traffic Analysis Toolbox Volume X: Localized Bottleneck Congestion Analysis

In the past, much, or all, of recurring congestion was felt to be a systemic problem ("not enough lanes") but much of the root cause of recurring congestion is in fact subordinate locations within a facility; i.e., "bottlenecks" and chokepoints. Elsewhere on the same facility and during the same hours, the facility runs free. This document is meant to discuss when, where and how to study small, localized sections of a facility (e.g., on/off ramps, merges, lane drops, intersections, weaves, etc.) In cost-effective means. Some chokepoints are (or seem) obvious in their solution; add a turn lane, widen a stretch of highway, retime a signal, or separate a movement by ramp. However, the solution can often lead to hidden or supplementary problems; hidden bottlenecks, disruptions upstream, or undue influence on abutting accesses, etc Analyzing localized sections of highway is different from analyzing entire corridors or regions. Micro simulation analysis products vary in their target applications and purported results. This document will provide guidance that specifies the choice of analysis tools and inputs necessary to analyze localized problem areas. It also provides some guidance as to when analysis it warranted, and what data inputs are required.

Traffic Signal Operations and Maintenance Staffing Guidelines

This report provides a guideline to estimate the staffing and resource needs required to effectively operate and maintain traffic signal systems. The results of a survey performed under this project, as well as a review of the literature and other surveys indicated that agencies achieving a high level of signal system performance do so under a wide variety of conditions such as agency size, geography, system complexity and traffic conditions that do not adhere to the typical level of documented resource requirements. Accordingly, a set of performance-based criteria were developed to define requirements. The performance-based criteria are focused on establishing realistic and concise operations objectives and performance measures.
