2.  WHAT TRAVEL TIME & DELAY STUDY DETERMINES?
• Any time devoted to travel is a travel time.
• A travel time study determines the amount of time required to travel from one point to
another on a given route.
• Information may also collected on the location, duration, and causes of delays.
• Data also aid the traffic engineer in identifying problems at the location.
 APPLICATION OF TRAVELTIME AND DELAY DATA :
• Determine the efficiency of a route with respect to its ability to carry traffic
• Identification of locations with relatively high delay and the causes for those delay.
• Determine the traffic times on specific link for use in trip assignment models
• Performance of economic studied in the evaluation of traffic operation alternative that reduce
travel time.
• To evaluate the change in efficiency and level of service with time.

3.  THE VALUE OF TRAVEL TIME?
• The Value of Travel Time (VTT) refers to the cost of time spent on transport.
• It includes costs to businesses of the time their employees and vehicles spend on travel,
and costs to consumers of personal (unpaid) time spent on travel.
• The Value of Travel Time Savings (VTTS) refers to the benefits from reduced travel time costs.
• Travel time savings is often the principal benefit of a transportation project.
• Congestion relief projects are justified primarily by the reduction in travel time.
• Travel time savings can also lead to reductions in vehicle operating costs. Those
benefits are discussed below.
• Travel time costs tend to be significantly higher under congested and unpredictable
travel conditions.
1. A new lane is added to a freeway, increasing traffic speeds and decreasing delays.
2. A signal coordination strategy is implemented, allowing for faster travel along a
corridor.
3. An improvement to a transit system reduces waiting time or increases travel time
It can also reduce travel time on a parallel highway.

4.  ISSUES TO BE CONSIDERED WHEN SELECTING APPROPRIATE
VALUE FOR TRAVEL TIME SAVINGS:
1. Regional Differences in Wage Rates :
• Transportation improvements should be focused on richer areas rather than poorer
areas, since the richer areas yield a higher overall value for the same magnitude of time
savings.
2. Intercity vs. Local Trips
• The trip purpose can play a significant role in a traveler's value of time. A distinction
be made between intercity trips and local trips, with intercity travel typically involving a
higher time value because it usually occurs in conjunction with expensive services such
hotel stays, restaurant meals, and entertainment. Therefore, time saved during intercity
travel can be used for purposes that travelers value highly, so it is typically set at a
value than local trips.

5. 3. Small Travel Time Savings vs. Large Travel Time Savings
• The same unit value of travel time savings is typically used for both small and large
travel time savings.
4. Passenger vs. Driver Time
• Time savings would be valued more highly by the driver than the passenger.
5. Travel Time as a Benefit Rather than a Dis-benefit
• Travel time also becomes a benefit when transportation improvements improve
mobility (i.e., ability of more residents to use transportation to access more
destinations) or expand accessibility (i.e, ability to reach more job opportunities,
access to a larger workforce, or go to shopping, social, or recreational destinations
within a given travel time). In such cases, people may gladly make use of
transportation improvements to travel to more distant destinations that are
to them.
6. Value of Time Depends on Types of Transportation Models Used

6. Category of proposal for travel
time reduction
Examples of proposals
Accommodate Needs Without Growth in
Mobility Demand
• Jobs or housing balance in subareas
• Affordable housing in employment centres
Accommodate mobility demand without
expanding infrastructure
• Ride sharing programs
• Increase in transit service
• Bicycle sharing program
Maximize Efficiency of Existing
Transportation Infrastructure
• Intelligent Transportation Systems
• Operations and maintenance
Expand Railroad, Transit, Bicycle and
Pedestrian Infrastructure
• Bikeways and pathways
• High Occupancy Vehicle lanes/Busways/Bus Rapid
Transit
Expand Streets and Highways
Infrastructure
• General purpose streets and roadways
• Limited access highways/freeways
 DIFFRERNT CATEGORIES AND PROPO SALS TOREDUCE TRAVEL TIME

7.  PROPOSAL TO BE MADE IN THE DEVELOPEMNT PLAN TO REDUCE
THE TRAVEL TIME :
 Widening of roads which are facing heavy traffic congestion.
 Neighbourhood development
• work area and resident in proximity ,
• availability of daily needs near residence)
– which reduces long trips and helps to reduce traffic congestion to reduce the travel time
(ex. Barcelona – neighbourhood development )
 Enhancement of public transport ( Encourage public transport )
 Improved transportation options
- biking and walking
- transit and ridesharing
 Incentives to use alternative modes and reduce driving
- telework and flexible work schedule
- universal transit passes
 Provide alternate routes for roads with heavy traffic

8.  Increased densities in transit corridors
 Landuse management
 Mixed use development
 Proper parking facility
- Reduces traffic congestion due to improper street side parking resulted in to reduction in
travel time
- Priority parking for carpools, vanpools and short term parkers
