The US 7174 National Electrical Manufacturers Association (NEMA) has published NEMA TS 5-2017 Portable Traffic Signal Systems (PTSS) Standard. This new standard covers traffic signalling equipment used to enable and expedite the safe movement of vehicle traffic in work zones during roadway construction, such as single-lane road closures during emergencies and planned events.

PTSS are commonly used to supersede flag use during roadway construction. While PTSS are used most commonly for single-lane road closures, they are also used during or after times of emergencies, planned events and non-normative vehicular signalisation needs.

PTSS are also used before or while permanent signals are being installed to reduce traffic bottlenecks and improve intersection safety during these transition times. PTSS are designed to enable critical movement of traffic using the implementation of appropriate new and existing standards.

    Israel aspires to ITS-led future
    Shay Soffer, Chief Scientist with the Israel National Road Safety Authority, talks to Jason Barnes about his country’s current ITS outlook and how he sees this developing in the future. Israel ranks alongside countries such as the US and France in the road safety stakes, with an average 7.1 deaths per billion kilometres driven. But at that point the similarities end, as the country’s overriding issue is pedestrian safety. This is driven by several factors, including being a relatively small country where pe

    Smart signal software ‘has potential for ICM’
    Software developed by researchers from the University of Minnesota for the Smart (Systematic Monitoring of Arterial Road and Traffic Signals) signal system automatically collects and processes data from traffic signal controllers at multiple intersections. It then creates performance measures, including information on the times and locations congestion occurs on a roadway. A new version of the software has been deployed at more than fifty intersections managed by the Minnesota Department of Transportatio
