• Understanding of sustainable transport• Analysis of urban travel in Karachi• Public Transport options• Recommendations
Presentation covers
A sustainable transportation system is one that:
Environment
Economy Equity
• Allows the basic access needs of individuals to be met safely and in a manner consistent with human and ecosystem health, and with equity within and between generations.
A sustainable transportation system is one that:
Environment
Economy Equity
• Is affordable, operates efficiently, offers choice of transport mode, and supports a vibrant economy.
The Accessibility approachIncreased speed can result in a proportionally larger increase in accessible area.
Implications:• More and faster travel increases accessibility.• Congestion can limit accessibility by a particular mode.• Efforts to increase automobility can reduce other forms of accessibility.
Use of indicators
*VMT = Vehicle Miles Traveled
*
Urban Land Use A sustainable transportation system minimizes the
use of land. Transport uses land directly (roads, driveways,
transport corridors, parking) Personal transport allows low-density
development of urban areas ->urban sprawl. Low residential densities make it
economically impossible to justify public transit…
-> the cycle of car dependency increases.

Urban public transport options
Bus Rapid Transit
• Premium transit using rubber tire vehicles• Dedicated running way• Fewer stops than local bus• Distinct stations, vehicles,
and systems• Allows flexibility to operate
multiple routes
LAMATA BRT Buses – Ojota Depot
LAMATA Bus Shelter – Ilupeju
Streetcar or Light Rail Transit
• Street Car or Light Rail Vehicle: An electrically propelled rail vehicle operated singly or in trains on shared, semi exclusive, or exclusive right-of-way
Fixed Guide way Vehicles• Automated guide way
small and medium-sized vehicles that operate fully automatically on guideways with exclusive rights-of-way
• Typically on a loop or as a shuttle within central business districts, airports or other high activity centers
Light Rail Transit
• Modern version of traditional streetcars
• May operate alongside auto, rail traffic• Reduces costs• Increases travel time
• Stations 1∕3-1½ miles apart
Heavy Rail• The term heavy rail is often used
for regular rail, to distinguish from systems such as light rail, monorail, Street car etc.
• Heavy rail typically refers to the standard inter-city rail network, which is built to be robust enough for heavy and high-speed trains, including freight trains, and long distance passenger trains.
Commuter Rail Transit
• Similar to passenger railroad service
• Existing railroads with improvements• Sidings• Additional tracks
• Long-distance commuting
• Stations 1½ -5 miles apart
