Carpooling Who, why and how


The essence of casual carpooling is that people want to get to work and home as painlessly as possible. Since, for example, the average congestion speed on themost-heavily slugged DC-region corridor is 14mph while the HOV lanesmove along at 65, picking up two slugs can decrease a driver’s commute time asmuch as 75 per cent. About half of all slugs and drivers, surveys on both


coasts indicate, are female and about a third drive and pick up sluggers on occasion and casual carpool the rest.Most say time is the primemotivator, with money in second place since HOT lanes have begun to have an effect.When safety ismentioned, it is almost always about the quality of the driving, not about fears of violence or strangers. Proponents say these conditions appear to be


needed for the “cloud” to gather and start its own casual carpool:


1) Enforced, limited access HOT or HOV lanes. 2) Easy driving access to and fromthem.


3) A parking lot or other place with open access so riders and drivers can visually communicate.


4) Beginning points near transportation alternatives, like ametro or BART station.


5) Enough distance between beginning and ending points that taking HOV/HOT lanes is worthwhile for drivers.


6) Large employers seemto help. The Pentagon has perhaps themost slugs coming fromall over Northern Virginia, but onlymarginally from Maryland or DC where limited-access HOV lanes are scarce.


7) Electronics and socialmedia can help – web sites in both DC and San Francisco provide locations, benefits and discussion boards while smart phone apps are beginning to show up – but slugging has been built on a word-of-mouth, first-person reality.
