Section 1300: Traffic Control Devices
IDSP Applicability & Operational Guidance
Overview
Section 1300 establishes standards for traffic control devices including sign structures, supports, and mounting systems. It covers structural requirements, placement criteria, and coordination with federal MUTCD standards.
Why It Matters to IDSP
IDSP staff coordinate sign installations across multiple programs (LOGO, TODS, Wayfinding, Gateway). Section 1300 helps you understand:
- • What structure types are standard vs. require special review
- • When to escalate to engineering for placement or design questions
- • How to coordinate with districts on structural requirements
What Decisions It Informs
This section informs operational coordination decisions, not design decisions. Use it to understand when a proposal is standard vs. when engineering review is needed.
- • Reviewing sign structure types proposed by contractors
- • Evaluating mounting and placement constraints
- • Coordinating with MUTCD requirements
- • Understanding standard vs. non-standard structures
- • Preparing for district coordination meetings
- • Structural design calculations
- • Foundation engineering decisions
- • Load calculations or wind analysis
- • Approving design exceptions
- • Making safety determinations
