- Reduction in the vehicle operation cost
- Reduction in the travel time and resultant benefits in terms of time cost of vehicles and passengers.
- Reduction in the accidents rates.
- Ease of driving and improved level of services.
- increased comfort to the passengers.
- Highway users benefits:
- Quantifiable or tangible benefits in terms of market values and
- Non-quantifiable or intangible benefits.
- Quantifiable Benefits:
- Saving in vehicle operation cost is due to the reduction in the fuel and oil consumption and reduction in wear and tear of Tyre and other maintenance costs. A road with sharp curves and steep grades require frequent speed changes;presence of intersections require stopping idling and accelerating; vehicle operation on road stretches with high traffic volume or congestion necessitate speed changes and stopping and increased travel time; all these factors result in an increase in every component of vehicle operation cost. Un-even pavement surface condition with ruts, pot holes, undulations, waves and corrugations increases the vehicle operation cost due to increase in fuel consumption, tyre wear and the general maintenance cost of the vehicle.
- Saving in travel time is of direct consequence to commercial vehicles due to possible increase in their trip length and earning per unit time. Benefits due to saving in travel time may be assigned in terms of time cost of vehicles.
- Value may also be assigned for the saving in travel time of passengers. A part of the time saved by the passengers or commuters may be used for some useful purpose and a value can be assigned for the saving in the travel time.
- The reduction in the accident rate due to improvements in the highway facilities causes considerable benefits to the road users and others. The component of the accident costs may include cost of damages to vehicles and other properties, cost for investigations, legal proceedings etc.
- The benefits to other than road users include the enhancement in land value, increase in the employment opportunities and related economic uplift.
The non- quantifiable benefits due to improvements in highway facilities include reduction in fatigue and discomfort during travel, increase in comfort and conveniences and improvement in general amenities, social and educational aspects, development of recreational and medical services, improved mobility of essential services and defense forces, aesthetic values, etc. Yet another important intangible road user benefit is the reduced suffering and pain of those involved in highway accidents.
- Non- Quantifiable Benefits:
