Speed detection systems get smart

It might be argued that speed limits are almost pointless because it is part of everyone’s genetic makeup, it seems, to speed. Similarly, drivers can’t act as though they are travelling each day on a German autobahn where there is no general speed...


Once caught and cited, offenders seem to get the message that a citation will be hard to contest. When they realize their speeding offense has been documented with lidar, they are less likely to dispute the offense in court. Courts today readily accept officers’ evidence of speeding via lidar. “The laser’s tough to beat, and judges and defense attorneys recognize this,” Officer Williams said.

In-car video systems provide indisputable proof

Video is one of the best tools available to make an offense nearly impossible to dispute. In fact, the majority of cases are uncontested the moment the defendant learns of video evidence. One of the industry titans is Digital Ally Inc., whose DVM-750 in-car video system is compelling. The most significant feature of this model is the ability to connect up to four cameras and simultaneously record from two of them, plus four separate audio channels. The cameras offer high resolution to provide the best quality images, ensuring that every detail of a speeder and his car are recorded. Along with video and audio, the system can record event and vehicle data, including velocity of the speeder, which can be displayed alongside or on top of the footage of their infraction. Furthermore, the DVM-750 has integrated GPS with a “mark” feature to flag important locations or events in the recording. Also included is the VoiceVault Advanced Wireless Microphone featuring On-Board Solid State Memory that records audio evidence when going out of range or the signal is interrupted. VoiceVault offers a range of up to one mile by automatically adjusting the transit power as the range increases.

Next app: The mobile phone

With the impressive technology advances for speed enforcement so far, a natural question arises: When will speed enforcement applications be put on a mobile phone? LTI anticipated this question and unveiled their Speed Capture mobile app in August 2013. The app functions with the LTI TruSpeed SX dual-purpose speed and mapping laser and Bluetooth, and can be used via iPhone, iPad or Android device. With the app, a traffic officer can save or send an image of a speeding offense along with ancillary information such as car make, model and color; date/time of offense, name of the officer and more.

According to Vinny Alvino, LTI’s Traffic Safety Product Manager: “The two great aspects of this application are that the officer will be able to save a photo (of the speed offender), record this, and then show a breakdown of the infraction on the smart device to the offender right on roadside.”

Speeding is a natural instinct, and for many drivers it’s an unshakable habit. Therefore, any possible solution—from radar to lidar to mobile apps— will be relevant since law enforcement agencies vary as to their choice of technology.

The most important aspect of the technology revolution in speed enforcement is that the evidence yielded will be undeniable in a courtroom. That alone should help speeders think twice about contesting a speeding citation, and the decision to speed in the first place.
