National City deploys new signal preemtion technology

National City, in San Diego county, California, has installed Opticom multimode signal equipment to enhance safety and provide more efficient traffic signal preemption and management. Currently, more than 70 intersections are equipped with infrared (IR) signal priority technology, most of which are Opticom devices. This allows emergency responders to activate green lights en route to their destination. With the new multimode technology installed at eight intersections, traffic signals can be triggered using

RSSNational City, in San Diego county, California, has installed Opticom multimode signal equipment to enhance safety and provide more efficient traffic signal preemption and management. Currently, more than 70 intersections are equipped with infrared (IR) signal priority technology, most of which are Opticom devices. This allows emergency responders to activate green lights en route to their destination. With the new multimode technology installed at eight intersections, traffic signals can be triggered using IR or global positioning system (GPS) activation technology for even more control and efficiency.

"The National City landscape is unique, with steep hills and winding roads," said Mayor Ron Morrison. "GPS allows our emergency responders to trigger green signals from significantly further distances away from intersections. It will enhance safety for our citizens and emergency responders. And it will help us save lives."

The technology allows staff to monitor Opticom equipped intersections remotely in real-time for more efficient system management. Its central management software (CMS) offers remote monitoring capabilities to minimise the need for time-consuming trips to the intersections, which in turn reduces maintenance costs.

    David Crawford looks how workzone safety can be ‘economically viable’. Highway maintenance is one of the most dangerous construction industry occupations in Europe. Research from The Netherlands on fatal crashes indicates that the risk facing road workzone operatives is ‘significantly higher’ than that for the general construction workforce. A survey carried out by the Highways Agency, which runs the UK’s motorway and trunk road network, has suggested that 20% of road workers have suffered injuries from pa

    Collecting speed and travel time data without using roadside infrastructure could offer new possibilities to cash-strapped road authorities. Streaming video may be useful for traffic controllers to monitor incidents and automatic number plate recognition may be required for enforcement, but neither are necessary for many ITS functions. For instance travel times, tailbacks, percentage of vehicles turning, origin and destination analysis can all be done using Bluetooth and/or WI-Fi sensors and without video o

As the world's roads become increasingly crowded, consumers and businesses are demanding better real-time information to help them both avoid traffic congestion and make smarter use of public transport. Embedding mobile connectivity directly into vehicles can enable drivers and passengers to see live traffic flows in their localities, as well as the expected arrival time of the next bus, ferry or tram
