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
