IMSA Traffic Signal II study plan

Redraw a full set of signal plan sheets from memory structure: title block, plan view, phasing diagram, wiring schedule, and notes block, labeling the purpose of each

Compile a personal symbol legend of at least 30 standard traffic signal plan symbols (heads, detectors, conduit, pull boxes, poles, span wire) with a one-line definition for each

Trace a signal phasing diagram into a written phase sequence table showing movements, overlaps, and protected vs permitted left turns for a 4-approach intersection

Explain aloud, in under 5 minutes, how a plan-view layout maps to the physical field arrangement of poles, heads, and cabinet

Define and write out every standard interval type (minimum green, passage/gap, yellow change, all-red, pedestrian walk and clearance) with the field condition each protects

Compute yellow change and all-red intervals for three approach speeds using the standard kinematic formulas, showing all units and assumptions

Build a complete timing sheet for one 4-phase intersection including min green, max green, extension, yellow, all-red, and pedestrian intervals

Distinguish actuated, semi-actuated, and pretimed operation and list two field clues that identify each in an existing cabinet

Convert a written operational need (e.g., left-turn protection, pedestrian crossing time, ADA-compliant crossing) into specific plan and timing requirements

Diagram a coordinated arterial time-space progression for three intersections at a fixed cycle length and compute offsets

Compare lead-lag vs lag-lead left-turn phasing and write down which conditions favor each

Identify at least 6 common plan-reading errors (wrong detector call, missing clearance, mismatched head count) and describe how each shows up in the field

Sequence the installation workflow from staking and conduit to pole setting, head hanging, cabinet wiring, and turn-on, listing the inspection checkpoint at each stage

Write a pre-installation checklist covering clearances, foundation specs, grounding, service disconnect, and controller cabinet placement

Describe correct termination and labeling practices for cabinet wiring and articulate why mislabeled conductors cause later troubleshooting errors

Perform a mock inspection of a written installation scenario and record every defect you can identify

Diagnose five written fault scenarios (no detection, flashing operation, conflicting indications, dark head, loop failure) by listing the first three test steps and expected readings for each

Explain the role of conflict monitors and how a flash condition is triggered and cleared

Measure and interpret voltage, continuity, and resistance readings with a multimeter given sample values, stating pass/fail and next action

Identify the top 5 documentation items a maintenance technician must record after any repair

Build a preventive maintenance schedule with intervals for lamp/LED checks, detector testing, cabinet cleaning, battery backup, and conflict monitor testing

Differentiate preventive, corrective, and emergency maintenance and give one realistic work order example for each

Practice writing a work order and a closeout record for a completed repair, including parts used, tests performed, and sign-off

List the safety precautions to take before opening a cabinet or entering the roadway for a repair

Plan a temporary traffic control setup for a signal maintenance closure, specifying taper, buffer, advance warning, and pedestrian routing

Match the appropriate standards and code references to at least 10 field situations (clearance, grounding, work zone device spacing, pedestrian access)

Identify the required personal protective equipment and high-visibility apparel for day and night work and state when flaggers or spotters are needed

Explain how to maintain accessibility and temporary pedestrian signals during construction

Re-derive the two weakest calculations from weeks 1-7 without notes and check accuracy

Write and answer 60 original practice questions distributed evenly across all five domains

Review every logged error from prior weeks and rewrite each as a corrected one-line rule

Rehearse the full exam flow under a timed sitting and record per-domain scores
