Getting Behind the Wheel With Real-Life Traffic Monitoring

Getting Behind the Wheel With Real-Life Traffic Monitoring

Traffic monitoring applications are taking place all over the world. Some of the latest installations feature rugged transmission, hybrid video systems and scalable management software.




AMG Systems supplied managed ruggedized Ethernet switches for its local partner ITNL in India. ITNL is using the transmission equipment for the new 74-mile addition to Highway No. 8, which the company is implementing as a build, operate and transfer project on behalf of the Indian Government's Ministry of Road Transport & Highways.

The project covers a new stretch of Highway No. 8. This addition has two toll plazas, each with six lanes, including one extra-wide lane in each direction. The toll system was developed in-house by ITNL and operates as a semi-automated collection system with automatic vehicle classification, slow-speed weigh-in-motion and lane controllers installed at all toll plazas. Each lane has a camera for incident capture.

The climate in Rajasthan is hot, sandy and often dusty. ITNL selected ruggedized industrial Ethernet equipment from AMG Systems. The AMG solution provides redundancy in case of link failure. ITNL is using managed switches with two links between the control room and the lane, so if one link fails, it automatically switches to the redundant link.

The AMG solution transmits all signals from auxiliary equipment, cameras and DVRs. The solution also covers lane traffic lights and overhead lane signs. There is a provision to connect both toll plaza control rooms to each other as well as to the head office. The solution has been further designed to incorporate future expansion, such as more toll lanes and IP-based surveillance.

DVTel's VMS was deployed in four Indian cities — New Delhi, Dehradun, Kashipur and Rudrapur. Optimum Tech Solutions served as the security integrator of record for the projects in Dehradun, Kashipur and Rudrapur and has been instrumental in growing the project in these cities.

The DVTel solution manages a mix of network fixed and PTZ cameras monitoring upwards of 40 locations total in the four cities. In each city, video is monitored by police to improve travel flow and enhance safety, but also to monitor traffic movement around the cities to respond quickly to terrorist or related threats. The Delhi project is managed by New Delhi city police, while the other three locations' city surveillance programs fall under the Uttrakhand State Traffic Police. The DVTel system is highly effective, particularly during festivals, when the entire city takes to the roads in celebration, and when VIPs are on the move in any of the cities.

The Delhi installation is the oldest of the four projects and the other three cities owe their inspiration for their projects from city officials visiting Delhi to observe its surveillance program in action. Video surveil-lance in India is experiencing strong growth, due mainly to perceptions of heightened terrorism threats. The DVTel solution was deployed for all four locations based on the recommendations of the trusted integrator partners as well as its demonstrated system performance first in Delhi and then in Dehradun, the capital city of Uttrakhand state.

IndigoVision's integrated IP video system provides monitoring for a traffic calming system in the Belgian city of Antwerp. The video system monitors a series of automated bollards that regulate traffic on a number of the city's streets, alerting the Antwerp police to malfunctions, accidents and acts of vandalism.

The bollards can be lowered automatically during predetermined hours or when buses and trams pass using onboard transponders. Local residents and other authorized people can gain access using a smart card reader or by entering a PIN code via a keypad. The access control system shares the same network as the IP video for communication back to the local traffic center that is the equipment hub for the project. The surveillance video is then relayed to the Antwerp police over a fiber network 6 miles away, where it is monitored and recorded. The traffic system was installed by TV Vialis- Paque, a joint venture between Vialis Traffic BV and Yvan Paque, which was created specifically for this project.

The police operators use IndigoVision's management software to view live and recorded video from the cameras monitoring the bollards. IndigoVision's MPEG-4 based compression technology ensures that high quality video and data can be transmitted over large distances with minimal impact on the available bandwidth, without image degradation and with negligible latency.

Operators can view video images that are as good as analog and have smooth PTZ camera control even though their monitoring center is located 6 miles away from the cameras. The high-quality video allows the police to easily identify the license plates of vehicles that have been involved with incidents or that have damaged the bollards.
