Universal goals-
1)Eradicate poverty 2)Ensure social equity
Planning tools-plot ratio
"total building floor" area/site area
Alternative transportation
-EV(electric vehicle) -TOD transit oriented development (reduce pollution,reduce congestion but improve mobility)
Objective of sustainable transportation in energy reduction
-alternative fuels -electric vehicles -eco-driving
Sustainable city
-compact & effective land -less pollutions & waste
Sustainable city
-compact & effective land -less pollutions & waste -sustainable economy -less private car;greater accessibility -preserve local culture -efficient use of resources
Model interfaces includes
-complement -compete
Sustainable development planning-
-create extra living space -recreation -preserve heritage areas -safeguard transport corridors[road etc]
Transport demand
-derived(not direct needs) -spatial -temporal
Objective of sustainable transportation operation
-encourage mass transport -manage transport demand (during peak hour) -better traveller information -minimize energy on single trip
Good planning
-improve welfare through develop attractive places for present & future generations
Good planning
-leaves sufficient resources for future generation
Long-term planning challenges-
-lifestyle changes -inaccurate projection or estimation -technology -vested interests
Urban challenges-
-minimise wasteful land consumption -reduce air pollution -provide utilities -proper waste treatment
Urban challenges-
-minimise wasteful land consumption -reduce air pollution -provide utilities -proper waste treatment -provide transportation choice -use of topography of land -eliminate water pollution
Transport planning [consideration]-
-mobility -connectivity -environment -safety -liveability -social equity
Basic concept of sustainability-
-no ultimate supply of resources -greater population,greater depletion rate -migitate(reduce)the problem through increase supply & reducing wasteful practices -conserve resources for future generation use
Planning tools-
-plot ratio -building coverage ratio -height control of building
Sustainable city
-preserve local culture -efficient use of resources
Urban challenges-
-provide transportation choice -use of topography of land -eliminate water pollution
Type of landuse zoning-
-recreational -commercial -industrial -residential -agricultural
Sustainable development[objective]-
-reduce loss of land for development -maintain vitability & viability of towns & cities -support safe and efficient movement
Objective of sustainable transportation planning
-reserve transport for future -reduce travel needs/demand -reduce landuse for facilities
Land use planinng-
-select landuses to meet certain needs & safe guard resources -decision involve may affect air,water,& environment -serve diversity needs of comunitties/populations
Route choice based on...
-shortest -fastest -cheapest -most scenic -comfort level
Sustainable city
-sustainable economy -less private car;greater accessibility
Sustainable city
-sustainable economy -less private car;greater accessibility -preserve local culture -efficient use of resources
Congestion taxes (not toll)
-tax payable to reduce travel time affect: -travel mode -travel time -travel route -location choice of individual travel behaviour
Urban development/planning
-technical & political process -develop land use,protection & use of environment,design urban environment -land use & transportation planning
Fail in planning means more population stay & live?
No
Plan & build to meet current needs only?
No
Plan & build to meet future needs only?
No
Success in planning means more population migrate away?
No
Demand function
Short run:affect by $ Long run:affect by other cost,activity,policy
Plan & build to meet current needs & preserve heritage & resources for future?
Yes
Success in planning means more population stay & live?
Yes
Accessbility
ability to reach certain destination
Planning tools-building coverage ratio
area of buidling occupied(largest)/site area
Sustainable development[objective]-
balance demands for limited land
Quantitative measurement-
base on measurement of: 1.economic/employment trends 2.population 3.international situation
Pricing and subsidy policies
based on AC & MC MC>Ac congestion MC=Ac no congestion
Sustainability crisis-
consumption of stock(natural,natural,human,social capital) faster than production.
Equilibrium
demand & supply function satisfied no disturbance in market (under optimmum condition)
Road classification...
design road for different speed/purpose
Sustainable development-
development to meet present needs & without affect the ability of future generation to meet their own needs
Consumer surplus
difference between the amount that consumer willing to pay and the actual amount the consumer paid higher=better economic utility higher=advance service/facility,lower fare linear relationship
Planning for human settlement-
different land use & modes of transportation
Bad transport management...
divide comunities traffic congestion road safety issue pollutions
Total cost
fixed cost + variable cost
Qualitative measurement-
governemnt policies & goals
Land use planinng-
involve either recreational,commercial,industrial,residential usage planning
Transportation network consists...
nodes & links
Planning tools-height control of building
not affect -air navigation -telecommunication -surroundings
Mobility
physical travel methods (sea,air or land)
Future planning
recycle land multi function land use work life balance
Economic of scale
reduce average cost by improve output/usage
Transport planning-
relationship between transportation & economic,society,environment
Economic models in transportation
require large data input for prediction & analysis
Transport supply
service involve infrastructure & vehicles may cause congestion due to limited capacity
Landuse zoning-
through legislation for subdivided land -allowable landuse -allowable conditions -allowable regulation requirement
Sustainable transport
through solving problems & not pass down to future generation &allow future generation to deal with future problems
