1 ARC’s Strategic Thoroughfare Plan Bridging the Gap from Travel Demand Model to Micro-Simulation GPA Conference Fall 2012 Presented By: David Pickworth, PE

2 The Project Arterials are the most challenged facilities in Atlanta Competing travel interests Cohesive planning, operations, and management EFFICIENT PROJECT IMPLEMENTATION

3 Overall Project Goals Prioritized arterial roadway network Develop guidelines on management and design Create a Geographic Database Perform case studies to test concept designs

4 Case Studies Transportation Assessment for MMCS 5 Case Study Corridors Case Studies selected based on differing developments, area types, and roadway configurations

5 Case Studies Strategic Regional Thoroughfare Plan Case Studies Aviation Blvd./Conley Rd. – Clayton County Moreland Ave. – Fulton County Memorial Dr. – DeKalb County Roswell Rd. (SR 9) – Sandy Springs/Rowsell McDonough Rd. (SR 155) – Henry County

6 The Problem Regional Subarea Corridor Develop An Analysis Process That Maintains, And Is Consistent With, The Overall Travel Pattern Relationships Established In The Regional Travel Demand Model Through Several Levels of Analyses

7 Analysis Provided Regional Subarea Corridor Regional Travel Patterns Establish Peak Period Travel Routes (DTA) Detailed Transportation System Operations During Peak Hours  Highway  Transit  Pedestrians

8 The Process Regional Travel Demand Model Application (Daily Trips) Matrix Variegation Procedure (Hourly Trips) Peak Period (AM and PM) Traffic Assignments Extract Peak Period (AM and PM) Subarea Network and Trip Tables Matrix Estimation Procedure (If Required) Subarea DTA AM and PM Peak Period Assignments Traffic Counts VISSIM Model Network Development VISSIM Model Application Extract AM and PM Peak Period Trip Tables For Corridor Evaluation Measures

9 Evauation Measures Study Area (AM & PM Peak Period) Vehicle Miles of Travel (VMT) Vehicle Hours of Travel (VHT) Average Peak Period Speeds Vehicle Hours of Delay Corridor (AM & PM Peak Hour) Average Speeds Average Vehicle Delay (Seconds) Approach & Intersection Level of Service (LOS) Transit Boardings (Daily) Queue Lengths By Facility Type

10 Example Study Area Network Roswell Road (SR9)

11 Example Corridor Network (VISSIM) Memorial Drive Corridor VISSIM Network

12 Example Corridor Network (VISSIM) Memorial Drive N. Hairston Raod Memorial Drive Corridor

13 Example Roswell Rd. Study Area DTA Assignment Animation

14 Roswell Rd. Corridor Continuous Flow Intersection Concept Animation

15 Roswell Road (SR 9) at Riverside Road/Azalea Drive 2040 PM Peak Hour RTP 2040 PM Peak Hour Scenario Improvement (Continuous Flow Intersection)

16 Conclusion Use regional travel demand model Bridge the gap between different local agencies for consensus in development strategies Using the appropriate tools to “funnel” travel demand down to peak hour microsimulation-level traffic More information: www.atlantaregional.com
