Concepts and theories used to analyze traffic flow, including traffic volume, speed, and density.

Fundamentals of Traffic Flow Theory: This topic will cover the basic aspects of traffic flow theory, including the definition of traffic flow, variables that impact it, and methodologies for measuring and analyzing traffic flow.
Traffic Flow Models: Traffic flow models aim to predict the characteristics of traffic flow such as speed or density under different scenarios. Understanding traffic flow models is critical to designing effective traffic management strategies.
Capacity and Level of Service: Capacity refers to the maximum number of vehicles that can pass through a segment of roadway in a given period of time. Traffic engineers must be familiar with capacity and level of service concepts to effectively plan and design traffic infrastructure.
Traffic Safety: Traffic safety is critical to protect lives and reduce accidents on the roadway. Traffic engineers must be familiar with measures for enhancing pedestrian safety, improving signage, and reducing collisions.
Traffic Congestion: Traffic congestion refers to situations where the demand for transportation exceeds the capacity of the roadway network. Traffic engineers must be familiar with congestion management strategies to reduce delays, maintain mobility, and optimize the use of resources.
Traffic Control Devices: Traffic signals, stop signs, and other traffic control devices are used to regulate traffic and improve safety. Traffic engineers must understand the principles behind these devices, their effectiveness, and how to install and maintain them.
Intelligent Transportation Systems (ITS): ITS combines advanced communication and information technologies with transportation systems to improve safety, mobility, and efficiency. Traffic engineers must be familiar with ITS applications and technologies to design effective systems.
Public Transportation: Public transportation is an integral part of urban mobility. Traffic engineers must be knowledgeable about public transportation options, their operation, and integration with other transportation modes.
Sustainable Transportation: Sustainable transportation aims to minimize the impact of transportation on the environment and encourage the use of alternative modes of transportation. Traffic engineers must be familiar with sustainable transportation concepts, including bike lanes, pedestrian walkways, and electric vehicles.
Traffic Data Analysis: Traffic engineers must be able to analyze data on traffic activity, usage patterns, and travel behavior to support effective transportation management and policymaking. Understanding and interpreting data is a key skill for traffic engineering professionals.
Macroscopic traffic flow theory: It focuses on the overall traffic flow characteristics at a macroscopic level, such as traffic volume, density, and speed.
Microscopic traffic flow theory: It examines individual vehicle movements and interactions at a detailed level, such as car-following behavior, lane-changing behavior, and acceleration and deceleration behavior.
Kinematic wave theory: It describes traffic flow as a wave-like phenomenon, where traffic congestion and flow behave like waves.
Fluid-dynamic traffic flow theory: It applies the principles of fluid dynamics to study traffic flow, treating traffic as a fluid and analyzing traffic flow in terms of traffic density, flow, and speed.
Queueing theory: It models traffic flow as a queueing system, where vehicles queue up at bottlenecks such as intersections, toll gates, and work zones.
Simulation-based traffic flow modeling: It uses computer software to simulate real-world traffic conditions and predict traffic flow patterns.
Intelligent Transportation System (ITS): It refers to the use of advanced technologies such as sensors, cameras, and communication systems to manage and optimize traffic flow in real-time.
Safety analysis: It focuses on understanding how road geometrics, roadway and vehicle factors, and other environmental factors affect safety for motorists, pedestrians, and bicyclists.
