Travel Cost Method
Overview:
The travel value approach is used to estimateeconomic use values related to ecosystems or web sites which can be used forrecreation.
The technique can be used to estimate theeconomic advantages or costs because of:
- modifications in access expenses for a recreationalsite
- removal of an current recreational website online
- addition of a brand new recreational website online
- modifications in environmental high-quality at a recreationalsite
This segment maintains with some exampleapplications of the travel cost method, followed by means of a greater entire technicaldescription of the technique and its advantages and boundaries.
Hypothetical Situation:
A site used mainly for recreational fishingis threatened by using development inside the surrounding vicinity. Pollution andother influences from this improvement ought to damage the fish habitat at thesite, resulting in a extreme decline in, or overall lack of, the web page’s abilityto offer leisure fishing services. Resource agency personnel wantto determine the fee of applications or movements to protect fish habitat atthe web site.
Why Use the Travel Cost Method?
The journey fee approach became selected inthis case for two fundamental reasons:1. The web site is by and large valuable to peopleas a recreational site. There are no endangered species or otherhighly specific features that would make non-use values for the website online enormous.
2. The expenditures for projects to protectthe website online are incredibly low. Thus, using a incredibly inexpensivemethod like journey price makes the maximum experience.
Alternative Approaches:
Contingent valuation or contingent choicemethods could also be utilized in this example. While they might producemore specific estimates of values for specific characteristics of the web page,and also should seize non-use values, they might be substantially morecomplicated and high priced to use.
Options for Applying the Travel CostMethod:
There are several approaches to method theproblem, the usage of variations of the journey fee technique.
These include:
Application of the Zonal Travel CostApproach:
The zonal tour fee approach is the simplestand least high priced approach. It will estimate a price for recreationalservices of the website online as a whole. It can't without difficulty be used to valuea change in high-quality of endeavor for a domain, and might not bear in mind someof the factors that may be important determinants of price.
The zonal tour cost approach is appliedby collecting records at the quantity of visits to the website online from differentdistances. Because the tour and time prices will increase with distance,this statistics permits the researcher to calculate the number of visits“purchased” at one-of-a-kind “expenses.” This statistics is used to constructthe demand function forthe site, and estimate the customer surplus, or economic advantages, for the recreational services of the website.
Step 1:
The first step is to define a hard and fast of zonessurrounding the web site. These can be described by way of concentric circlesaround the website online, or by geographic divisions that make experience, together with metropolitanareas or counties surrounding the web page at special distances.
Step 2:
The 2nd step is to accumulate informationon the range of visitors from each quarter, and the range of visits madein the ultimate yr. For this hypothetical example, count on that staffat the site hold information of the variety of visitors and their zipcode, whichcan be used to calculate overall visits in keeping with sector over the past 12 months.
Step 3:
The third step is to calculate the visitationrates in step with one thousand population in every area. This is truely the totalvisits in line with year from the sector, divided via the quarter’s population in heaps. An instance is shown inside the table:
ZoneTotal Visits/YearZone PopulationVisits/a thousand0400100040014002000200240040001003400800050Beyond 30 Total Visits1600
The fourth step is to calculate the averageround-ride journey distance and travel time to the website for each sector. Assume that human beings in Zone zero have zero journey distance and time. Each other area can have an increasing tour time and distance. Next, the use of average fee in step with mile and per hour of travel time, the researchercan calculate the travel price in keeping with journey. A wellknown fee in keeping with milefor operating an vehicle is with no trouble available from AAA or different assets. Assume that this value in keeping with mile is $.30. The value of time is morecomplicated. The handiest method is to use the common hourly wage. Assume that it's miles $9/hour, or $.15/minute, for all zones, although in practiceit is in all likelihood to differ through region. The calculations are proven in thetable:

The 5th step is to estimate, the usage of regressionanalysis, the equation that relates visits in line with capita to travelcosts and different vital variables. From this, the researcher canestimate the demand function for the average visitor. In this simplemodel, the analysis might consist of demographic variables, together with age, profits,gender, and training tiers, the use of the common values for each sector. To keep the only viable model, calculating the equation withonly the journey fee and visits/1000, Visits/one thousand = 330 – 7.755*(TravelCost).
The 6th step is to construct the demandfunction for visits to the website, using the results of the regression analysis. The first point at the call for curve is the whole traffic to the website atcurrent access charges (assuming there's no access rate for the website online), whichin this situation is 1600 visits consistent with yr. The different points are foundby estimating the variety of visitors with exclusive hypothetical entrancefees (assuming that an front rate is regarded in the identical way as travelcosts).
For the purposes of our example, startby assuming a $10 entrance rate. Plugging this into the estimatedregression equation, V = 330 – 7.755C, gives the subsequent:
ZoneTravel Cost plus $10Visits/1000PopulationTotal Visits0$1025210002521$20.5017120003422$31.009040003603$52.00080000
This gives the second one factor on the demandcurve—954 visits at an access rate of $10. In the identical manner, the numberof visits for increasing access costs can be calculated, to get:
Entry FeeTotal Visits$20409$30129$4020$500
These factors supply the call for curve fortrips to the web site.

The very last step is to estimate the totaleconomic benefit of the website online to visitors via calculating the customer surplus,or the area underneath the demand curve. This consequences in a complete estimateof monetary benefits from leisure makes use of of the website online of round $23,000per year, or around $14.38 in line with go to ($23,000/1,six hundred).
