Texas DOT, institutes demonstrate wrong way driving alert system

In a joint partnership with the Texas Department of Transportation (TxDOT), Texas A&M Transportation Institute (TTI) and Southwest Research Institute (SwRI) are researching wrong-way driving, reports the Houston Chronicle. Almost 240 wrong way crashes happen each year in the state, according to the TTI. More than half of those resulted in a fatality crash.

In a joint partnership with the 375 Texas Department of Transportation (TxDOT), 8520 Texas A&M Transportation Institute (TTI) and 5690 Southwest Research Institute (SwRI) are researching wrong-way driving, reports the Houston Chronicle.


Almost 240 wrong way crashes happen each year in the state, according to the TTI. More than half of those resulted in a fatality crash. Researchers said most of those crashes occur at night, with alcohol impairment often a factor. On freeways, the most common way for someone to drive the wrong direction is to enter the freeway on an off-ramp.

Using connected car technology, TTI and SwRI researchers have demonstrated a system which alerts the traffic control room and warns not only the wrong-way driver but also other motorists and law enforcement. Warnings can also be displayed on dynamic message signs.

Texas already has some exit ramps equipped with warning lights for wrong way drivers. 797 Harris County Toll Road Authority has extensively lined tollway exits with warning lights. TxDOT has used the system at ramps with a history of wrong-way drivers in the Houston area, while TranStar has relayed information using the message signs along freeways.

    According to a new analysis of the City of St. Louis' violator-funded red-light safety camera program carried out by safety camera supplier American Traffic Systems (ATS), drivers are adopting safer driving habits by stopping at red lights. As drivers comply with the law, the risk of dangerous red-light running collisions is reduced, and streets become safer for drivers, pedestrians and cyclists. The study reviewed nearly 350,000 red-light running violations issued in the city from the time the program bega

    Machine vision offers new solutions to old problems
    The transportation sector is set to benefit from a far wider range of machine vision technology. While machine vision techniques have been applied to traffic management applications for some years, in some areas there can still be a shortage of knowledge about what the technology can offer transportation professionals. The image processing and interpretation functions of machine vision enables control room staff to be immediately alerted to occurrences requiring attention which, in turn, enables each person
