Study Notes
Urbanization
- Urbanization is the shift from a rural to an urban society.
- Level of urbanization is the percentage of people living in towns and cities.
- Rate of urbanization is how quickly the level of urbanization grows.
Factors Driving Urbanization
- Natural increase: More births than deaths in urban areas, driven by fertility rates and quality of healthcare systems.
- Rural to urban migration: A major factor, especially in developing countries, where migration accounted for 40% to 60% of urban growth.
- International migration: Significant in gateway cities leading to trickle-down effects in smaller cities.
Spatial Imprint of Urban Transportation
- Pedestrian areas: Space for walking, often sharing road space with sidewalks taking 10-20% of the right-of-way.
- Roads and parking areas: Roads account for 30% of urban space, and off-street parking takes another 20%.
- Cycling areas: Dedicated bike lanes and parking facilities are becoming more common, with the Netherlands being a leader.
- Transit Systems: Buses and trams often share space with cars, which can hinder their efficiency. Dedicated bus lanes are implemented to reduce congestion.
- Transport terminals: Ports, airports, transit stations, and distribution centers require significant urban space to accommodate globalization's impact on mobility.
Urban Transportation Analysis
- Trip generation: Predicts the amount of trips originating or ending in a specific area.
- Trip distribution: Allocates trips generated in one zone to other zones within a city.
- Modal split: The use of various transportation modes, influenced by cost, technology, availability, preferences, travel time, and income.
- Trip assignment (routing): Determines the routes used for journeys within the city, often influenced by congestion and trip chaining.
Urban Transport Challenges
- Traffic Congestion and Parking Difficulties: Common in large cities, exacerbated by car ownership and increased demand for infrastructure.
- Recurrent Congestion: Routine traffic volume on normal days.
- Non-recurrent Congestion: Unexpected incidents like accidents, road closures, weather, and poorly functioning traffic signals.
- Longer Commuting: Driven by affordability, with residents choosing more affordable housing further from central areas. This leads to isolation and health issues.
- Public Transport Inadequacy: Transit systems can be overcrowded during peak hours or underutilized in suburbs. Many systems struggle to generate enough revenue to cover costs.
- Difficulties for Non-Motorized Transport: Pedestrians and bicycles are hindered by heavy traffic and poorly designed infrastructure.
- High Infrastructure Maintenance Costs: Aging infrastructure requires costly maintenance and upgrades, creating disruptions.
- Environmental Impacts and Energy Consumption: Pollution, noise, and high energy consumption are consequences of urban transportation.
- Accidents and Safety: Increased traffic leads to more accidents and fatalities, especially in developing countries.
- Land Consumption: Transportation, particularly cars, requires substantial land use.
