Transportation System
Management (TSM)
• Application of methods & procedures for increasing
the efficiency & utilization of existing facilities.
• Emphasis on making better use
resources rather than planning new

of

existing

• Objective is to shift the focus from high capital
approaches to low cost, more rapid implementable
projects.

Travel Demand
Management
• Volume vs Time and
Peak Hours Capacity
• Methods for
Influencing the
Demand
– Shifting the temporal
distribution of demands
– Reducing the
Magnitude of Demand
– Repackaging the
demand

Shifting the Temporal
Distribution
• Methods aim at flattening the
volume-time curve at peak hours.
• Achieved by
– Staggered Working Hours
– Flexible Working Hours

Reducing the Magnitude of Demand
• Methods aim at reducing the traffic
demand at around a place.
• Achieved by:
– Shorter working weeks
– Shorter Average trip length by shifting
city centres to smaller cities &
decentralized locations
– Work from home facility

Repackaging the Demand
• Methods stress on the mode of
transport to influence the demand.
• Achieved by:
– Better facility of public transport
– Encouraging/compulsory car pooling
– Parking Restraint
– Priority for buses

Traffic Management
• Retaining the existing pattern of
streets but altering the pattern of
traffic movement on these.
• Reorienting traffic pattern on the
existing streets so that the conflicts
between vehicles and pedestrians is
reduces.

Traffic Management
Measures
• Restriction on turning movements
– Separate turning phase in signals
– Prohibition on turning movement

• One way Streets
• Tidal Flow Operations
• Exclusive Bus Lanes

Advantage of One Way
Streets
• Reduction in points
of conflicts
• Increased capacity
• Increased speed
• Progressive Signals
• Improved Parking
• Elimination of head
on collision

Disadvantage of One Way
Streets
• Increased distance
• Relocation of bus stops
• Increased severity of
accidents due to speed
• Adverse effect on
business of area
• Prerequisite need of
alternate street system
• Bottleneck to
emergency vehicles
