题目内容
Ever driven into a traffic jam just after the guy on the radio said the road was all clear? Or prepared yourself for the crowdedness he warned about only to zip right through?
A large number of private companies say they have the one thing that can ease such frustrations: better information.
Now one of those companies, SpeedInfo Inc., has fixed 50 solar--powered, wireless radar sensors along main roads in the District of Columbia that take readings of average traffic speeds twice a minute in both directions.
The company says the sensors provide a far more accurate picture of road conditions than can be collected from helicopters or highway patrol alerts.
In a business model that SpeedInfo hopes will develop around the country, the San Jose, California--based company is letting the city use the data for traffic planning free of charge, in exchange for access to the side of the road. Speedlnfo plans to sell the information to paying customers, including broadcasters and companies that provide information for in--car navigation equipment.
The problem with traditional traffic reports is that in most of the country, they rely on highway patrol accident reports that come 30 to 40 minutes late and a few helicopters that get into the sky during rush hour, SpeedInfo Chief Executive Doug Finlay said.
"Chopper Bill gets in the sky and says, 'Oh, I'm looking at the road and the cars are going slow, " Finlay said."Chopper Bill is the best data you got."
Tim Lomax, a researcher at the Texas Transportation Institute, said a recent increase of high--tech traffic data systems is good for drivers.
"Even if it doesn't get rid of traffic crowdedness, they at least give people an idea of what sort of choices they're facing and more control over their destiny, which is part of the frustrating element of traffic crowdedness," Lomax said.

When I was about 13, my father would take me on short outings on Saturdays. On the way home, Dad _36_ stopped at the Dairy Queen for 10-cent ice creams. I couldn’t _37_ it, but I could pray from the _38_ we started heading home to that corner where we would either go straight for the ice cream or _39_ and go home empty-handed. That corner _40_ either mouth-watering excitement or _41_.
On one special day, we were heading home, and again I was praying for the _42_ sound of his offer. It _43_. “Would you like an ice cream today?” “That sounds great, Dad!” But then he said, “How would you like to _44_ today?”
Twenty cents! My mind reeled(震惊). I could afford it. I got a weekly allowance of 25 cents, plus some _45_ for odd jobs(零活). But _46_ it was my money, ice cream wasn’t a good use of it. In a fit of _47_, I said, “Well, in that case, I guess I’ll _48_.” My father just said, “Okay, Son.”
But as we headed home, I realized how wrong I was and begged him to _49_. But he just said, “That’s okay, we don’t really need one.” I felt _50_ for my selfishness and ungratefulness. He didn’t mind, or _51_ act disappointed.
I _52_ that generosity（慷慨）goes two ways and gratefulness sometimes costs more than “thank you”. On that day gratefulness would have cost 20 cents and it would have been the _53_ ice cream I’d ever had.
I’ll tell you one more thing. We _54_ another trip the next week. As we _55_ the corner, I said, “Dad, would you like an ice cream today? My treat.”
