Project Goals
Key Study Activities Stakeholder Involvement Compilation of Local Land Use Plans Develop Travel Demand Model Existing Conditions Evaluation Future Needs Evaluation Identification and Evaluation of Alternatives for Study Area Case Study Analysis The Public Steering Committee Stakeholder Project Team We are here
Technical Process Perform three levels of analyses to identify potential needs and solutions Evaluate study area conditions (macroscopic) Evaluate corridor-level conditions and travel patterns (mesoscopic) Perform detailed analysis of eight selected case study areas (microscopic)
Strategy Development and Evaluation Process
Major Travel Corridors Three-Tier Approach A2A Travel Demand Model Macroscopic Model Develop broad range of improvement strategies to meet study goals Evaluate LOS, travel time, delay, speed for study area Major Travel Corridors Mesoscopic Model Evaluate LOS, travel time, delay, speed by corridor Assess impact of potential improvement strategies applied to various situations Case Study Areas Microscopic Model
1st Step - Build the Travel Demand Model Integration of ARC , Athens, & Statewide models Multimodal Non-motorized travel Highway Auto (SOV, SR2 & SR3+) Truck (Medium, Heavy & Commercial) Transit Bus Heavy Rail (HT) Bus Rapid Transit (BRT) Light Rail (LT) Commuter Rail Used for the Analysis of Study Area and Major Travel Corridors
Building the Model Final Atlanta to Athens Network (3800+ Zones) ARC Plan 2040 Network (1700+ Zones) Jackson County Network From GA Statewide Model (27 Zones) ARC Updated Network Clipped Study Area (780+ Zones) Athens-Clarke County Network From MACORTS Model (332 Zones) Downtown Athens Study Area Clipped Downtown Atlanta

Purpose of Major Travel Corridors Focus on routes used for regional travel More detailed analysis at corridor-level Use stakeholder input to test and evaluate Improvement Strategies in these corridors
Major Travel Corridors Done Major Travel Corridors
Evaluation of Major Travel Corridors Utilize dynamic traffic assignment Develop list of potential improvement concepts or templates that can be selectively applied to various situations throughout study area Assess potential success associated with each of identified improvement concepts Most efficient and cost-effective
