Radar Detection Errors: Causes and Controls
A radar detector can appear to be functioning normally while introducing a serious operational problem: a side-road phase that calls unnecessarily, a cyclist who is not detected at the stop line, or vehicle data that no longer reflects actual network conditions. Radar...
Signal Fault Diagnosis for Smarter Junctions
A junction can appear to be operating normally while making poor decisions. A missed cyclist call, an occupied detector channel, intermittent radar target loss or a delayed controller response can each create avoidable delay and safety risk. Effective signal fault...
Best Vehicle Classification Tools for UK Roads
A missed HGV, a cyclist counted as a motorcycle, or a queue recorded as free-flowing traffic can distort the decisions that follow. The best vehicle classification tools are therefore not simply those with the longest feature list. They are the systems that produce...
Speed Display Effectiveness on Real Roads
A speed information display can attract a driver’s attention in a fraction of a second. Whether that moment translates into safer speeds at the point of risk is the real test. Speed display effectiveness is not determined by the brightness of the sign or the...
