NCHRP 7-22 Planning & Preliminary Engineering Applications Guide for the HCM Kittelson & Associates 01/12/15 1 Status Report

The NCHRP 7-22 Project Purpose: ◦ To develop a guide on the use of the HCM for planning and preliminary engineering applications by  identifying appropriate methods and applications, illustrating them with case studies. End Date ◦ June 3,

The People The Research Team ◦ Kittelson & Associates - Rick Dowling, Paul Ryus ◦ Bastian Schroeder, ITRE; Tom Creasey, Stantec ◦ Mike Kyte, Univ.of Idaho; Danica Rhoades, Write Rhetoric 3 The Panel Dirk Gross (Ohio) (Chair)Tyrone Scorsone (CSI) Robert Bryson (Milwaukee)Brian Dunn (Oregon ) Jessie Jones (Arkansas)Subrat Mahapatra (Maryland) Erik Ruehr (VRPA)Andrew Wolfe (SUNY) Doug McLeod (Florida)Jeremy Raw (FHWA)

The Process Literature Review, Critique HCM, Outline Get Stakeholder Input for Critique. ◦ (1 st round workshops) Interim Report 1 st Draft Guide to Panel and Stakeholders ◦ (2 nd round workshops) 2 nd Draft Guide to Panel and HCQS (Dec 2014) 3 rd And Last Draft Guide to Panel (March 2015) 4

The Guide Should Cover: 1.Appropriate use of HCM for a broad spectrum of planning and preliminary engineering applications (including different stages, different scales, and system performance monitoring); 2.Appropriate uses for different parts of the HCM (e.g., appropriate use of default values); 3.Use of the HCM in scenario planning; 4.Coordinated use of HCM with simulation models, travel demand forecasting models, mobile source emissions models, multimodal transportation analysis tools, and other tools; and 5.Use of the HCM in evaluating oversaturated conditions in a planning context. 5

The Guide Part I - Introduction ◦ Types of Analyses, Defaults, Serv. Vol Tables Part II – Mid-level Analyses ◦ Facility and intersection analyses ◦ Ped, bike, transit, truck Part III – High-level Analyses ◦ Corridors, regions Part IV – Case Studies, Example Apps. 6

Case 3 - LRTP 2040 Regional Transportation Plan - 6,000 square miles - 1 million population 17

Example Problems Example Problems that Develop Demand Model Inputs ◦ Example I.1 – Estimation of Free-Flow Speeds and Capacities ◦ Example I.2 – HCM Based Volume-Delay Functions Example Problems Post Processing Demand Model Outputs ◦ Example I.3 – Speeds for Air Quality & Noise Analysis ◦ Example I.4 – Screening for Auto V/C and LOS Hot Spots ◦ Example I.5 – Predicting Queues & Delay ◦ Example I.6 – Interpretation of Results ◦ Example I.7 – Prediction of Reliability ◦ Example I.8 – Transit, bicycle, and pedestrian LOS screening ◦ Example I.9 – Truck LOS screening 18

Case 4 – System Monitoring State produces annual report on state highway system performance. Over 12,000 center-line miles Three different monitoring station types ◦ Some collect AADT only (e.g. HPMS) ◦ Some collect hourly speed data (e.g. INRIX) ◦ Some collect simultaneous hourly spot speeds and volumes (loop detectors) 19

Case 4 – Example Problems IV.1 – Estimate Monitor Site Capacities & Free-Flow Speeds IV.2 – Estimate Monitoring Site Speeds from Volumes IV.3 – HCM Assisted QA/Quality Control IV.4 – Computation of Modal Performance Measures 20
