General assumptions

Monthly time and costs
We have used average monthly time and average monthly cost for commute options as of October-December 2018. This makes sense as commuters who use public transportation like train and bus or use vanpool service are purchasing monthly tickets or paying monthly fees. Also, drivers who park in Rosslyn, VA typically pay for parking on monthly basis. We use 20 commuting days in one month derived from 22 work days minus 2 days for telecommuting and other reasons for not commuting.

We did not make any adjustments for the tax deduction or compensation from the employer which depends or the residence status and the employer.

Commute start
We have used 8:00 am as a time when commuters arrive in their offices and 4:30 pm as a time when commuters leave their offices. So we were calculating commute duration based on commuting in respective hours. This seems to be the typical case for the majority of commuters for this commute route.

Commute locations
For morning pick-up location we have used Leesburg Park and Ride Commuter Lot in Leesburg, VA:

  • Leesburg Commuter Lot, Nearest Address: 19730 Sycolin Rd, Leesburg, VA 20175, USA.

We have used 1100 Wilson Blvd, Arlington, VA for the office location in Rosslyn as a middle point to highly concentrated employment areas in Rosslyn, Arlington, VA

Assumptions by commute options

Commute by Local Bus + Metrorail
We have used Loudoun County Transit website as a source of price and time information between Leesburg, VA and Wiehle-Reston East Metro station in Reston, VA and WMATA website as a source of price and time information of commute between Wiehle-Reston East Metro station and Rosslyn Metro station in Rosslyn, VA.

Commute by Commuter Bus
We have used Loudoun County Transit website as a source of price and time information of commute between bus stops at Leesburg Park and Ride Commuter Lot (Address: 19730 Sycolin Rd, Leesburg, VA 20175) and Lee Hwy & N Nash St, Arlington, VA.

Commuters who use commuter bus will not be using other means of transportation to get to their office and walk time is not accounted for.

Driving alone regular lanes
Drivers pay more than just fuel costs. In addition to gas, driving expenses include other costs such as maintenance, repair, and tires. We did not include relatively fixed driving cost related to car ownership: car depreciation, insurance, registration, license, taxes, finance charges, other costs such as car wash because those costs are not directly driven by the commute.

We have assumed that parking in Arlington, VA costs $135.

For driving time we have used Google Map to estimate commute duration between Leesburg Commuter Lot, Nearest Address: 19730 Sycolin Rd, Leesburg, VA and office at 1100 Wilson Blvd, Arlington, VA.

Driving alone express lanes
Driving alone express lane includes all cost of driving alone regular lanes. In addition, driving alone express lanes requires paying the toll. We have used expresslanes websites for toll and time calculation on I-66 Express Lanes, Dulles Toll Road and Dulles GreenWay for the commute time frames under consideration.

Commute by Vanpool
Vanpool cost is calculated based on the fees vanpool providers are charging and the assumption of driving van 10% of the times for driving credit.

In addition to the driving time, we are adding 5 minutes each way for dropping off vanpool participants and waiting for pickups.

Commute by Carpool
Carpooling is another ridesharing option that is quite efficient.
For carpool, we are assuming that there are 2 people in the carpool who are taking turns in driving their own cars and share parking in Arlington, VA. That is why the cost of carpool is 1/2 of driving cost.

In addition to driving time, there are 2 minutes each way of waiting for carpooling partners at pick-up and for detouring for drop-off.

Using Sameride Commute

Sameride Commute allows drivers to use HOV/HOT express lanes without paying tolls and allows riders to commute for free. This type of commute is similar to slugging or carpooling but it is on-demand and provides commute to and from office (custom drop-off and pick-up). So it is more convenient and predictable both for drivers and riders. Commute time with Sameride is less than driving alone on express lanes because of using I-66 and Dulles Toll Road HOV-2 lanes.

Sameride Commute is the cheapest option to commute for riders – it’s free. And it is the best money- and time-saving option for drivers.

We have added 1 minute of waiting/detouring for Sameride commuters.

Flexibility is another criteria that we have compared commute option against. The smile emoji corresponds to the level of flexibility. Metrorail, bus, vanpool or carpool commuters are less flexible because of schedules and/or long-term commitments. Sameride Commute can be used once, every day or a few times a week when it is needed. Sameride doesn’t require any long-term commitments. Also, you can request/offer a ride for the time that works the best for you.
