Transportation Engineering

Civil Knowledge:

Q1:What is transportation engineering?

A: Transportation engineering is a branch of civil engineering that deals with the planning, design, operation, and maintenance of transportation systems.

Q2:What are the different modes of transportation?

A: The different modes of transportation include roadways, railways, airways, waterways, and pipelines.

Q3:What is traffic engineering?

A: Traffic engineering is a sub-discipline of transportation engineering that focuses on studying and managing traffic flow, including traffic control, traffic signal timing, and transportation planning.

Q4:What is the purpose of transportation planning?

A: Transportation planning aims to develop policies and strategies to efficiently and safely move people and goods while considering social, economic, and environmental factors.

Q5:What is a traffic impact study?

A: A traffic impact study is a study conducted to assess the impact of a proposed development or project on the surrounding transportation network.

Q6:What is the Level of Service (LOS) in transportation?

A: Level of Service (LOS) is a measure used to evaluate the operational performance of transportation facilities, such as roads or intersections, based on factors like speed, congestion, and delay.

Q7:What is the capacity of a roadway?

A: The capacity of a roadway refers to the maximum number of vehicles that can pass through a given point on the road within a given time period.

Q8:What is the purpose of traffic signals?

A: Traffic signals are used to control the flow of vehicular and pedestrian traffic at intersections, improving safety and facilitating efficient traffic movement.

Q9:What is a roundabout?

A: A roundabout is a circular intersection where traffic flows continuously in one direction, eliminating the need for traffic signals or stop signs.

Q10:What is the purpose of traffic calming measures?

A: Traffic calming measures, such as speed humps or traffic circles, are implemented to reduce vehicle speeds and improve safety in residential areas or near schools.

Q11:What is the Highway Capacity Manual (HCM)?

A: The Highway Capacity Manual (HCM) is a widely used reference manual that provides guidelines and methodologies for evaluating highway and roadways' capacity and operational characteristics.

Q12:What is Intelligent Transportation Systems (ITS)?

A: Intelligent Transportation Systems (ITS) refer to the integration of advanced technologies, such as sensors, communication systems, and data analytics, into transportation infrastructure to improve safety and efficiency.

Q13:What is the concept of Complete Streets?

A: Complete Streets is a design approach that aims to create roadways that are safe and accessible for all users, including pedestrians, cyclists, and public transit users.

Q14:What is the purpose of a traffic impact fee?

A: A traffic impact fee is imposed on developers to help fund transportation infrastructure improvements their development necessitates.

Q15:What is a transportation model?

A: A transportation model is a mathematical representation of transportation systems that helps analyze and optimize the movement of goods and people.

Q16:What is a traffic simulation?

A: Traffic simulation involves the use of computer models to simulate traffic patterns and evaluate the performance of transportation networks under different scenarios.

Q17:What is transit-oriented development (TOD)?

A: Transit-oriented development (TOD) is a planning approach that promotes mixed-use, pedestrian-friendly neighborhoods centered around public transportation stations.

Q18:What is a transportation demand management (TDM) program?

A: Transportation demand management programs aim to reduce travel demand or shift travel patterns through measures like carpooling, telecommuting, or flexible work hours.

Q19:What is a bike lane?

A: A bike lane is a designated part of a roadway that is reserved for bicycles, providing a safe and separate space for cyclists.

 Q20:What is a pedestrian crossing?

A: A pedestrian crossing is a designated area on a road where pedestrians can safely cross, often marked with crosswalks and accompanied by traffic signals or signage.
