I've been thinking a lot about the cost of driving a lot because I am working on a series of maps for our Microcarpool Project.
For the Microcarpool Project, UCLA Transportation selected five communities over 20 miles from UCLA that are adjacent to carpool lanes. Then we created maps with dots to represent where employees live. (The dots are extra big for privacy purposes.) Next, we will be sending out emails to people who live in those communities with the maps and links to Zimride and CarpoolWorld.
We wanted to test the idea of Density Disclosure. What on does that mean? Well, we wondered if people would be more encouraged to register their commute on Zimride and CarpoolWorld if they knew that a significant number of people lived near them.
In our email, we wrote that one good reason to carpool is the fact that driving is expensive. I relied on the Southern California club of AAA's 2009 "Your Driving Costs" report to figure out the cost of commuting per day and per month between the pilot communities and Westwood.
We determined that commuters traveling 20 miles each way were spending about $200 a month in operating and parking costs alone (assuming vehicle operating costs are 15 cents a mile). A carpooler could could save about $100 per month. Table 1 shows how much it costs to operate a car per month from the communities in our pilot:
Table 1. How much does it cost to drive and park at UCLA per month?
|Community||Avg one-way trip from UCLA||Round Trip Distance from UCLA||Average cost of driving||Average operating cost/mo||With Monthly Parking|
|$0.15/mi||20 work days||$63, yellow permit|
|Artesia and Cerritos||32||64||$ 10||$ 192||$255|
|Granada Hills||21||42||$ 6||$ 126||$189|
|Porter Ranch||22||44||$ 7||$ 132||$195|
|Simi Valley||34||68||$ 10||$ 204||$267|
|South Pasadena||22||44||$ 7||$ 132||$195|
Operating costs will vary by car type and the cost of gas.
Table 2 attempts to provide more information oncommuting cost per day based on car type (Note: This excludes the cost of parking).
