Study Notes
Transportation Demand Forecasting
- Essential for predicting future travel behavior and required transport facilities.
- Aims to inform policies and plans that align development with anticipated travel needs.
Forecasting Methods
- Trend Extrapolation: Utilizes historical data to predict future travel; low cost but risks inaccuracies if future behavior changes significantly.
- Econometric Modeling (DM-3): Analyzes economic factors and their interactions to predict travel demand; considers variables such as income and socio-economic characteristics.
- Four-Step Model: A structured technique including trip generation, trip distribution, mode choice, and route assignment to estimate travel demands.
- Simulation Model: Creates transportation networks to assess demand under various conditions.
- Land Use and Transportation Interaction Model: Evaluates potential traffic changes due to shifts in land use patterns and their effects on transportation.
Factors Affecting Travel Demand
- Population Growth: Increased density boosts travel needs due to more individuals needing to travel.
- Economic Development: Creates jobs and raises income levels, increasing travel demand through enhanced economic activities.
- Land Use Patterns: Distribution of residential, commercial, and industrial areas influences travel behavior.
- Transportation Infrastructure: Accessibility and quality of transport facilities impact travel choices.
- Technology: Innovations like electric vehicles and ride-sharing services can transform travel demand characteristics.
- Environmental Policies: Initiatives promoting public transport or cycling can reduce private vehicle use, aiming for a lower carbon footprint.
Transportation Impact Assessment
- Analyzes project impacts on the environment, society, and economy to aid decision-making and maximize benefits while minimizing drawbacks.
Environmental Impacts
- Air Quality: Transportation projects may lead to increased air pollution and contribute to climate change.
- Noise Pollution: Traffic congestion can result in higher noise levels, negatively affecting local residents' quality of life.
- Habitat Disruption: Construction activities risk biodiversity loss due to interference with natural ecosystems.
- Water Quality: Road runoff can result in water source pollution, affecting water quality.
Social Impacts
- Community Disruption: New transport projects may displace residents, disrupting social structures.
- Equity: Socio-economic changes due to transport development may benefit some while harming others, particularly marginalized groups.
- Accessibility: Improved transport enhances access to essential services, employment, and education, elevating quality of life.
Economic Impacts
- Cost-Benefit Analysis: Evaluates the economic viability of transportation projects by comparing potential costs and benefits.
