Introduction
• The process contains a Concept Development Phase and a Final Design Phase before project goes into Construction.
• TSM Procedure Manual
• Projects• Traffic Signal
• Adaptive • Signal Optimization
• ITS• Camera Surveillance Systems (CSS)• Dynamic Message Signs (DMS)• Truck Safety Warning Systems (TSWS)• Travel Time Systems (TTS)• Fiber Optic Network
Initiate CD
• Obtain Management System and Stakeholder input
• Update PRS• Update with all available information. PM responsible to
update regularly.
• Tier Assignment• If traffic signal project, tier is assigned to proposed
corridor based off the COAST-NJ study.
Data Collection & Analysis
• Perform Environmental screening
• Gather information needed such as As-builts, ROW information
• Field visit to verify and evaluate existing conditions
• TSM CD Checklist
• Identify existing utilities
• ITS Site location flexibility
Alternatives Analysis & CD Report
• Develop Alternatives• The alternatives should provide cost effective quality
solutions.
• Preliminary Preferred Alternative (PPA) is chosen.
• Designer develops a preliminary location plan based off the chosen PPA.
