  • Lesson 3 • Traffic Flow Fundamentals

    Covers the three core traffic flow variables: volume, speed, and density. Students apply the fundamental flow equation to real-world scenarios.

  • Lesson 4 • Regulatory and Standards Framework

    Surveys the regulatory environment, design manuals, and warrants that govern traffic engineering practice. Prepares students to apply standards correctly throughout the course.

  • Lesson 5 • The Traffic Engineering Profession

    Defines the scope, responsibilities, and ethical obligations of traffic engineers. Establishes professional context before technical content is introduced.

Chapter 2See details

Traffic Studies and Data Collection

  • Lesson 1 • Volume and Classification Counts

    Teaches manual and automated methods for counting vehicles and classifying them by type. Accurate counts underpin capacity and design analyses.

  • Lesson 2 • Data Quality and Statistical Analysis

    Addresses error sources, confidence intervals, and seasonal adjustment factors. Students validate datasets before using them in engineering analyses.

  • Lesson 3 • Origin-Destination and Parking Studies

    Explains survey methods for capturing trip origins, destinations, and parking demand. Data supports demand modeling and land-use impact analysis.

  • Lesson 4 • Study Planning and Scope Definition

    Covers how to define study objectives, select study locations, and determine required sample sizes. Proper planning prevents costly data gaps later.

  • Lesson 5 • Speed and Travel Time Studies

    Introduces spot speed studies, travel time runs, and delay measurement techniques. Results feed directly into operational analysis and safety assessments.

Chapter 3See details

Capacity and Level of Service Analysis

  • Lesson 1 • Arterial and Urban Street Analysis

    Evaluates arterial performance using travel speed and signal progression metrics. Connects intersection-level results to corridor-level level of service.

  • Lesson 2 • Capacity Analysis Concepts

    Defines capacity, saturation flow, and level of service as analytical constructs. Establishes the conceptual framework applied across all facility types.

  • Lesson 3 • Signalized Intersection Analysis

    Covers the full capacity analysis procedure for signalized intersections including delay estimation. This is the most commonly applied analysis in urban traffic engineering.

  • Lesson 4 • Basic Freeway and Highway Segments

    Applies capacity methodology to uninterrupted-flow facilities including basic freeway segments and multilane highways. Students calculate density and assign level of service.

  • Lesson 5 • Weaving, Merge, and Diverge Areas

    Extends freeway analysis to complex interchange areas where traffic streams interact. Students identify operational problems at weave and ramp junctions.

  • Lesson 6 • Unsignalized Intersection Analysis

    Analyzes two-way stop-controlled and all-way stop-controlled intersections using gap acceptance theory. Students determine capacity and delay for minor-street movements.

Chapter 4See details

Geometric Design for Traffic Operations

  • Lesson 1 • Horizontal and Vertical Alignment

    Teaches the design of circular curves, superelevation, and vertical curves. Alignment design must satisfy both driver comfort and minimum safety standards.

  • Lesson 2 • Roundabout Design Principles

    Covers entry geometry, circulatory roadway width, and splitter island design for modern roundabouts. Roundabouts offer safety and operational advantages over signalized intersections.

  • Lesson 3 • Cross-Section Elements

    Covers lane widths, shoulders, medians, curbs, and sidewalks as cross-section components. Each element is sized to balance capacity, safety, and context.

  • Lesson 4 • At-Grade Intersection Geometry

    Addresses channelization, turn lanes, corner radii, and sight triangles for at-grade intersections. Proper geometry reduces conflict points and improves throughput.

  • Lesson 5 • Design Speed and Sight Distance

    Establishes design speed as the controlling parameter and derives stopping, passing, and decision sight distances. Sight distance governs horizontal and vertical alignment choices.

Chapter 5See details

Traffic Signal Design and Operations

  • Lesson 1 • Cycle Length and Split Calculation

    Teaches Webster's method and critical-lane-volume approaches to determine optimal cycle length and green splits. Students produce a complete timing plan for a single intersection.

  • Lesson 2 • Signal Phasing and Phase Design

    Covers phase sequencing, protected and permissive left-turn treatments, and overlap phases. Phase design directly determines intersection safety and efficiency.

  • Lesson 3 • Signal Coordination and Progression

    Introduces time-space diagrams and bandwidth optimization for arterial signal coordination. Coordinated signals reduce stops and fuel consumption along corridors.

  • Lesson 4 • Actuated and Adaptive Signal Control

    Explains detector-based actuation, semi-actuated operation, and adaptive control algorithms. Students compare fixed-time and actuated strategies for varying demand patterns.

  • Lesson 5 • Signal Warrants and Justification
