Urban as Ecology Flashcards
Vibrations transmitted through air or another medium that can be detected by organs of hearing
Sound
An unexpected, undesired, or unpleasant sound
Noise
The disturbing noise with harmful impacts on the activity of human and animal life
Noise pollution
- Sleeping disorders
- Poor communication
- Headache, irritability, nervousness, fatigue
- Impacts on wildlife
Impacts of noise pollution
- Changes animal behavior
- Messes up bird migration patterns
- Reduces melatonin production
- CO2 emissions from electricity use
Impacts of light pollution
The phenomenon of higher temperatures in urban areas
Urban Heat Island Effect
- Shading from vegetation results in significantly cooler surfaces
- Transpiration removes heat from the air
Loss of Vegetation
Less effective at reflecting solar radiation albedo
Heat Absorbing Materials
Heat radiating out from buildings trapped by surrounding buildings
Urban morphology traps heat
- Cars, trucks, buses
- Air conditioning units
- Industrial facilities
Waste heat
- Increase in population
- Increase in trip lengths
- Increase in number of trips
- Decrease in vehicle occupancy
Reasons for growth in driving
- Traffic accidents
- Difficult weather conditions
- Unexpected spikes in traffic
- Bottlenecks
- Disable traffic control equipment
Causes of congestion
- Time lost
- Money lost
- Fatalities
- Air pollution
Costs of congestion
- Lane priority
- Signal priority
- Fare collection
- Rider appeal
- Land use policy
Elements of bus rapid transit
- Sidewalks & crosswalks
- Bike & bus lanes
- Medians
- Green spaces
Elements of complete streets
