• Wrong-way crashes on San Antonio highways happen more often than you might think

    Wrong-way crashes in San Antonio flew under the radar

    A few months ago, my boss, Express-News Projects Editor David Sheppard, asked me to see what we could find out about wrong-way crashes on highways. It seemed like there were a lot of these deadly accidents in the news lately, and local officials had recently unveiled a $500,000 pilot project to install flashing wrong-way signs and radar on a 15-mile segment of U.S. 281.

    I wrapped up what I was working on and teamed up with reporter Vianna Davila, who covers transportation. We had to answer two deceptively simple questions. How often do wrong-way crashes happen? And how does Bexar County compare to other counties?

    We turned to a giant database maintained by the Texas Department of Transportation called the Crash Records Information System. It’s derived from accident reports filled out by law enforcement officers, and it tracks hundreds of details about every accident in Texas — including wrong-way crashes.

    But we soon learned there was no quick and easy way to filter the data for the specific wrong-way accidents we were looking for — crashes on major divided highways with exit and entrance ramps.

    The database had a “road type” field, with categories that included interstates, tollways and U.S. and state highways. So far, so good. But some state highways are actually busy roads, such as Bandera Road. The wrong-way crashes on those boulevards are different from the type of accident we were examining. We weren’t writing about distracted drivers who cross a center line into oncoming traffic. We were writing about drivers who head up exit ramps and into oncoming traffic on busy highways and interstates.

    We ended up selecting the five Texas counties with the largest populations, mapped the wrong-way accidents with Google Fusion Tables, and then eyeballed each location to make sure it actually occurred on a major highway. Here’s how the finished product looked for Bexar County:

    It took hours of work but the result was a set of specific crashes we were looking for. And the final numbers were surprising — Bexar County ranked high in wrong-way accidents for the years 2007-2011. It even had more crashes than Dallas County, which is more densely populated and has more traffic. To our knowledge, no one has done this kind of comparison in recent years.

    If you work for a news organization and you’re jumping into data journalism (and you should be), it’s a good idea to share your methodology and findings with the government employees who oversee the data. You don’t want to be surprised by an error they catch after the story is published. And it gives the agency a chance to respond if your findings cast the agency in a harsh light.

    It was certainly surprising to learn Bexar County ranked so high. The other surprise was how long the deadly problem flew under the radar. Despite several high-profile, deadly wrong-way crashes, local officials didn’t start talking about ways to prevent them until the summer of 2010.

  • WOAI fought long battle to obtain TxDOT’s auto-accident data

    Wrong way signWOAI featured a unique, data-driven story last week about the high number of accidents caused by inattentive drivers talking on their cell phones. Journalists at the television station analyzed an accident database kept by the Texas Department of Transportation that tracks contributing factors for all vehicle crashes in Texas.

    To get the story, WOAI had to fight a lengthy open-records battle with TxDOT. During their legal dispute, TxDOT took the unusual step of asking a state senator to write a bill that, in its original form, would have kept the entire database private.

    The dispute between WOAI and TxDOT is a telling example of how difficult it can be to get important information out to the public. In some cases, it’s a long, expensive slog — it took nearly two years for WOAI to get its hands on the data.

  • Public litter data: Don’t Mess with Texas

    Don't Mess With TexasEven people living outside Texas have heard of Don’t Mess with Texas, the public relations campaign by the Texas Department of Transportation. TxDOT wants to persuade litter bugs to stop throwing trash out of their cars.

    Buy what exactly do people tell TxDOT when they report a litterer?

    In her newspaper column today, Peggy Fikac mentioned an interesting database we obtained recently of all littering complaints reported to TxDOT last year. If TxDOT can find a matching address to a reported license plate, the agency sends a friendly warning letter and litter bag to the alleged offender.

    There’s some interesting patterns in the data. For example, Texas is parched from a record drought, yet cigarette butts were the most frequent type of litter reported by the public. Many people noted the risk of wildfire.

    “Don’t Be a Butt!” one commenter wrote. “Keep your cigarettes in the car ashtray and help prevent fires! Thanks!”

    Some people also caught public workers littering: “I was surprised that the person littering was a DPS officer,” one complainant alleged. “I was disappointed to see (an) officer of the law break the law. The officer should be setting a example for the citizens.”

    At least two people spotted litterbugs in fuel-efficient Priuses: “You think you’re green with your Prius but littering hurts the world!”

    There was a Biblical commenter who simply wrote: “Revelation 11:18.”

    And I was impressed by the reporting skills of this commenter:

    “Man was a brunette, heavily built caucasian in tan cargo and tank top, tennis shoes in his early 40s. Threw the following out of parked SUV then drove off: 1 mcDonald’s chicken nugget, 1 piece of toy, 1 kids drink plastic cover, 1 straw, 2 bottles of water – one Kroger, the other brand I don’t recall; a plastic or rubber yellow and grey toy shark, a cardboard case bottom (possibly from a case of bottled water; cheetos empty bag, 2 dirty napkins, McDonalds large french fries holder. I did not confront driver because I was in my car and he was much much much bigger than me.”
