  • FE Civil Exam Prep 77, Signal Timing and Pavement Design

    FE Civil Exam Prep 77, Signal Timing and Pavement Design
    2026/07/13
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to apply Webster's optimal cycle length formula, C₀ = (1.5L + 5)/(1 − Y), for signal timing problems. - The critical distinction between the 'Y' for the sum of critical flow ratios and the 'Y' for the yellow interval calculation, a common exam trap. - The purpose of the AASHTO Structural Number (SN) in representing the overall strength of a flexible pavement. - How to solve for a required layer thickness (D) using the formula SN = a₁D₁ + a₂D₂m₂ + a₃D₃m₃. - The importance of including drainage coefficients (m₂ and m₃) for base and subbase layers, a frequent source of error on the exam.

    FE Civil Exam Prep 76, Highway Capacity — LOS, PHF, PCEs
    2026/07/12
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How Level of Service (LOS) A through F provides a qualitative grade for traffic conditions. - The correct formula for Peak Hour Factor (PHF) and how to apply it to find the design flow rate. - How to use Passenger Car Equivalents (PCEs) to account for the impact of heavy vehicles on capacity. - Common exam traps, such as inverting the PHF formula or misapplying the heavy vehicle adjustment factor. - Key factors that reduce a highway's free-flow speed, including lane width and lateral clearance.

  • FE Civil Exam Prep 75, Traffic Flow — Speed-Density-Flow and Greenshields

    FE Civil Exam Prep 75, Traffic Flow — Speed-Density-Flow and Greenshields
    2026/07/11
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The fundamental relationship of traffic flow is q = u·k, where q is flow (veh/hr), u is speed (mph), and k is density (veh/mile). - The Greenshields model provides a linear relationship between speed and density: u = u_f(1 − k/k_j), where u_f is free-flow speed and k_j is jam density. - Roadway capacity, or maximum flow (q_max), occurs precisely when speed is half the free-flow speed (u_f/2) and density is half the jam density (k_j/2). - A common exam trap involves recognizing that a single flow rate (other than capacity) can correspond to two different traffic states: one uncongested (high speed, low density) and one congested (low speed, high density). - Use the mnemonic "Max flow is at half and half" to quickly solve for roadway capacity without complex derivations.
