Study Notes

Transportation Engineering

  • Transportation engineering applies technology and scientific principles to design, operate, plan, and manage transportation infrastructure.
  • It focuses on mobility for people and goods, aiming for safety, efficiency, speed, comfort, convenience, economy, and environmental sustainability.
  • Transportation systems include roadways, railways, waterways, and intermodal operations.

Demand in Transportation Engineering

  • Demand refers to the expected traffic volume (people, vehicles, etc.) using a specific transportation facility.

Supply in Transportation Engineering

  • Supply is the quantity and type of infrastructure components (roads, bridges, pavements, etc.).
  • Infrastructure components are often large and expensive.

Types of Transportation Engineering

  • Railway Engineering: Trains are a complex transport method, requiring advanced systems for passenger and freight transport across vast distances and urban centers.
  • Port and Harbor Engineering: Involves the planning and building of wharves, docks, piers, berthing facilities, marinas, bulkheads, and seawalls for shipping, commercial fishing, and passenger transport. These engineers also oversee coastal access areas and survey services.
  • Airport Engineering: Focuses on the design, construction, maintenance, and standards for commercial, private, military, and civilian airports, heliports, and helipads.

Environmental Engineering

  • Environmental engineering is a field that involves sustainable design.
  • Its aim is to protect and control the environment and its resources.
  • It utilizes engineering, soil science, biology, and chemistry to develop solutions for environmental problems.
  • Solutions for environmental problems may be related to water quality, wastewater treatment, hazardous waste management, air pollution, etc.

Environmental Engineering: Goals & Activities

  • The goal is to ensure the sustainable use of water, land, and air resources.
  • Engineers study and address pollution questions related to water, soil, and air.
  • Engineers design and construct water and wastewater treatment facilities, plan for the disposal of wastewater and sludge, and deal with the processing and disposal of solid waste.

Renewable Energy Sources

  • Renewable energy sources are naturally replenished. Examples include solar energy, geothermal energy, wind energy, biomass, and hydropower.

Nonrenewable Energy Sources

  • Nonrenewable energy sources are limited (e.g., petroleum, hydrocarbon gas liquids, natural gas, coal, nuclear energy).

Sustainability in Construction

  • Sustainability assessment in construction projects aims to minimize negative impacts on the environment and ecosystem while optimizing construction costs.
  • Construction impacts include waste generation, vehicle emissions, noise pollution, and pollution of water and atmosphere.
  • Sustainable construction aims for resource efficiency, community support, biodiversity, and pollution reduction.

Environmental Engineering vs. Environmental Science

  • Environmental engineering focuses on creating solutions, while environmental science focuses on analyzing the cause of the problem.
  • Environmental engineers deal with applying scientific knowledge to practical problems, while scientists focus on gaining new knowledge and understanding of the problem.
  • Both fields use observation and analysis, but engineering focuses on creating solutions.
  • Environmental engineers tend to look at practical solutions such as sewage plants, disposal facilities, and waste management.
