Intersection Design
Intersection Design is a specialized area of traffic engineering that focuses on planning and creating safe, efficient road junctions where two or more roads meet. This includes everything from simple four-way stops to complex roundabouts and highway interchanges. Traffic engineers who work on intersection design make sure vehicles, pedestrians, and cyclists can move safely through these areas while minimizing delays and congestion. They consider factors like traffic signals, turn lanes, crosswalks, and accessibility features. It's similar to how an architect plans a building, but instead, these professionals plan how roads come together.

Example Interview Questions
Senior Level Questions
Q: How would you approach redesigning a high-accident intersection in a busy urban area?
Expected Answer: A senior engineer should discuss analyzing accident data, traffic patterns, and peak hours, then explain how they would consider multiple solutions like signal timing changes, adding turn lanes, or implementing roundabouts. They should mention stakeholder engagement and budget considerations.
Q: Tell me about a challenging intersection project you managed and how you handled competing priorities.
Expected Answer: Should demonstrate project management experience, ability to balance safety, cost, and community needs, and experience working with multiple stakeholders including city officials and the public.
Mid Level Questions
Q: What factors do you consider when determining if a traffic signal is needed at an intersection?
Expected Answer: Should mention traffic volume, accident history, pedestrian activity, and standard warrant analysis procedures. Should also discuss alternatives to signals and cost considerations.
Q: How do you accommodate pedestrian and bicycle safety in intersection design?
Expected Answer: Should discuss crosswalk placement, signal timing for pedestrians, bike lanes, visibility improvements, and ADA compliance requirements.
Junior Level Questions
Q: What are the basic elements of a safe intersection design?
Expected Answer: Should mention clear sight lines, proper signage, adequate lighting, turn lanes, crosswalks, and signal timing basics.
Q: What software tools do you use for intersection design?
Expected Answer: Should be familiar with basic CAD software, traffic analysis tools, and simulation programs used in the industry.
