When most people talk about rush hour traffic, they’re thinking about the frustrating congestion on roads during the morning and evening commute. Transportation engineers use a more technical term for the same idea: peak hour traffic. Understanding how traffic builds up during these busy times is crucial for designing roads, planning intersections, and evaluating new […]
Traffic Impact Assessments (TIAs) are critical tools that help municipalities understand how new developments will affect local transportation networks. These TIA guidelines provide a practical framework for preparing and reviewing TIAs in municipalities that do not yet have their own standards. The intent is to balance technical credibility with simplicity, ensuring municipalities can review studies
In traffic engineering, the K-factor is a critical parameter used in roadway design and traffic analysis. It represents the proportion of Annual Average Daily Traffic (AADT) that occurs during the design hour, and it allows engineers to size and evaluate roadways for their most critical operating conditions. Trying to calculate a traffic signal warrant? Try
Traffic signals are at the heart of modern intersections. Their timing not only dictates how efficiently traffic flows but also affects safety, pedestrian accessibility, and overall network performance. To design or evaluate a signal plan, engineers rely on a set of technical terms that describe how green, yellow, and red indications are distributed across phases
Transportation planning and engineering is one of the most dynamic and impactful career paths available today. It sits at the intersection of technology, infrastructure, sustainability, and public policy. If you’ve ever searched “Should I study transportation engineering?” or “Is traffic engineering a good career?”, this guide will help you understand why the answer is a
Fleet size refers to the total number of vehicles, vessels, or aircraft an organization owns or operates at a given time. While the definition sounds simple, the meaning and implications of fleet vary across industries—from public transit agencies and airlines to trucking companies, taxi services, and construction fleets. Whether you manage buses, trains, airplanes, or
Traffic engineering is full of nuanced concepts that help us better understand how roadways function under pressure—and one of the most important of these is the Peak Hour Factor (PHF). Whether you’re conducting a Traffic Impact Study (TIA), designing an intersection, or calibrating a simulation model, PHF plays a critical role in capturing the intensity
In road design, traffic load isn’t just about how many vehicles pass each day — it’s about how much stress those vehicles place on the pavement over time. That’s where ESALs come in. If you’re involved in pavement design, planning, or construction, understanding Equivalent Single Axle Loads (ESALs) is essential. This article explains what ESALs
Designing a durable and cost-effective road starts with a strong pavement foundation. In Pakistan, flexible pavement remains the most common choice for urban roads, highways, and access streets. But how do engineers determine the thickness of each pavement layer — from subgrade to asphalt? This article walks you through the basics of flexible pavement design
Fleet sizing is a foundational step in designing any public transportation system—whether it’s for buses, trains, or trams. Determining the right number of vehicles ensures that service levels are reliable, operational costs are optimized, and passenger demand is met throughout the day. In this article, we’ll explore how to calculate fleet size for public transit
