Travel Process IN India: |
Posted: November 4, 2014 |
The Value of Travel Time refers to the cost of time spent on transport, including waiting as well as actual travel. It includes costs to consumers of personal (unpaid) time spent on travel, and costs to businesses of paid employee time spent in travel. The Value of Travel Time Savings refers to the benefits from reduced travel time costs. Travel time is one of the largest categories of transport costs, and time savings are often claimed to be the greatest benefit of transport projects such as roadway and public transit improvements. Factors such as traveler comfort and travel reliability can be quantified by adjusting travel time cost values. On average people devote 60 -90 minutes a day to travel. Most people seem to enjoy a certain amount of personal travel, about 30 daily minutes, and dislike devoting more than about 90 minutes a day. Conventional transport evaluation often undervalues qualitative travel time cost factors which skews planning decisions to favor increased travel speed at the expense of other improvements. For example, conventional evaluation accounts for roadway widening travel time savings but not the additional delay it causes for walking and cycling (called the Barrier Effect described in chapter Similarly, reduced unit cost from improved walking conditions and more comfortable transit vehicles are seldom quantified and so are undervalued compared with projects that increase vehicle travel speeds Travel time is an internal cost. The main equity issue occurs if people who are transportation disadvantaged bear excessive travel time costs compared with those who are more advantaged. Travel time costs can be considered inefficient if users impose delay on other travelers (see Congestion Costs). Transportation project evaluation practices that value certain travel time savings (such as reduced motorist congestion delays) but not others (such as delays to pedestrians, or comfort and convenience to transit passengers) can result in inequitable planning decisions. Travel time costs are highly variable, including a small portion of travel with very high time values, to a significant portion of travel with little or no cost, since travelers enjoy the experience and would pay nothing to reduce it. High-time-value travel includes. Paid travel. Urgent personal trips. Travel under congested or uncomfortable conditions. Unexpected delays. Longer trips or high daily mileage
