Learie Hercules, VP product development, GTT: Minutes Matter
If you’re a fire chief or in charge of an ambulance department, you know that minutes count when responding to emergency calls. So, discovering which intersections tend to hold up your crews is potentially life-saving information.
GTT is showing the latest version of its Opticom Analytics tool, which maps the effect individual intersections have on traffic flow. Taking data from individual emergency vehicles, it plots the junctions they use most frequently and the level of delays they encounter.
The new application is visually easy to interpret. Intersections with emergency vehicle prioritisation (EVP) systems, which turn lights green as first responders approach them, are plotted on a city map as circles and those without EVP with squares. The varying size of the circles or squares indicates how frequently the vehicles use those locations and the length of delays they experience.
This allows emergency services to clarify the fastest routes when heading to different sectors of their area of responsibility. Armed with this information, a fire chief, for example, can issue instructions to his crews to use particular routes or go to the city’s traffic planners to ask them to alter traffic light timings.
GTT and its customers initially used the Opticom Analytics tool to speed transit vehicles and allow them to keep to timetables, but the earlier system was usually installed in traffic management centres and thus less available to other users. The new use extends its operational use by having the information from vehicles sent to a cloud-based system.
