While car sharing is a concept that’s catching on, old-fashioned carpooling where a group of people take turns driving each other to work has always faced a resistance (抗拒). In a study on traffic problems by ABC News, 84% of those who drive to work say that they still do it alone. More than half those lone riders insist that carpooling is just too inconvenient, and 18% say they simple don’t know anyone to share a ride with.

Now technology makes carpooling easier and more fun. NuRide, a company provided an online carpooling service last year, offers daily travelers in the Washington area not just a web-based list of would-be carpoolers but also a way to arrange a trip online. Here’s how it works: rider seekers enter the positions where their trip will begin and end, the time they want to leave and if they’re willing to drive or just ride in someone else’s car. The website’s search engine then looks for matches and makes lists of the names of traveling companions, along with the car model and the exact time and place to meet for each trip. People who want to share the ride can show their interest in joining in online and then meet their car mates when it’s time to go.

NuRide users aren’t riding with total strangers. They are required to provide the name of their employer and a work e-mail address, both of which need to be checked before being listed on the website.

To attract users, NuRide offers a frequent rider prize: anyone who shares a ride gets a $1 credit. So far, 2,300 people have signed up. NuRide CEO Rick Steele said that more than 50,000 rides have been arranged on the website, resulting in 1.4 million fewer miles driven and 650 fewer tons of automobile emissions (机动车排放).
