TSS shows Aimsun Online real-time traffic management system
TSS-Transport Simulation Systems is showcasing its Aimsun Online real-time decision support system for traffic management. One of the most high-profile traffic management projects to use Aimsun Online as its prediction engine is the award-winning Interstate 15 Integrated Corridor Management (ICM) project led by the San Diego Association of Governments (SANDAG). At the core of the project is the configuration and implementation of a Decision Support System (DSS) using Aimsun Online.

TSS-2195 Transport Simulation Systems is showcasing its 7320 Aimsun Online real-time decision support system for traffic management. One of the most high-profile traffic management projects to use Aimsun Online as its prediction engine is the award-winning Interstate 15 Integrated Corridor Management (ICM) project led by the 1789 San Diego Association of Governments (SANDAG). At the core of the project is the configuration and implementation of a Decision Support System (DSS) using Aimsun Online.
“The DSS gives system managers comprehensive awareness of the current and predicted performance of the entire corridor,” says Matthew Juckes, senior project manager at TSS. “Now managers can take proactive steps to prevent system breakdown using enhanced controls across devices such as traffic signals, ramp meters, and dynamic message signs.”
Taking it one step further, earlier this year SANDAG completed a ‘Coordinated Test Plan’ for the first ever ‘fully automated’ multi-modal corridor handling of a freeway incident. TSS says this is one of the first times in the US that a traffic management decision has been successfully made entirely based on automatically triggered real-time simulations of the entire multi-modal transportation network.
Another recent innovation to come from the ICM project is the free 511 San Diego mobile application which is available for iOs and 1812 Android. Funded by the 324 US Department of Transportation, the app provides real-time predictions from Aimsun Online and system based advisories, letting users view predictive travel times on I-15; current traffic conditions; MTS bus routes, fares, arrival times; as well as real-time dynamic toll rates for the I-15 Express Lanes. Since its launch in May 2014 it has already had over 25,000 downloads.
Sensefields’ traffic monitoring system uses easily installed wireless sensors to determine vehicle speed and, in urban situations, also for categorisation. Information from the sensor is sent in real time to the data processing station to determine the capacity (vehicles per hour) in each lane, average speed, speed distribution, average vehicle length, length distribution, density, average headway between vehicles and occupancy (%).
Swarco Traffic Americas has introduced its third generation of optic LED dynamic message signs (DMS) to the North American market. The third generation signs deliver contrast ratios more than double the NEMA TS4 requirement and are said to use a fraction of the power consumed by its competitors’ signs.
Portuguese company EST will present its new Android application for managing a Phonepark parking place. This application allows users to manage their private parking space and they may temporarily authorise its use by other users (30 different users). In case of parking space abuse, the owner of the space is immediately warned by sms, in the same way as the multi-user Phonepark. A new design and new features for the standard Phonepark will be shown at Intertraffic. EST says it plans to extend the implementa
Laser Technology is exhibiting its latest TruCapture and TruSense systems on its booth. TruCapture uses expanding optics to create an elongated laser beam with an optimum detection range of between 66 and 164ft (20 and 50m) and speed measurements are accurate within 3mph (5km/h) in traffic management mode and 1mph (1.6km/h) in enforcement mode.
