The effect of moving objects on the electromagnetic landscape set up by cellular telephony networks can be detected and interpreted to give real-time traffic data across large geographical areas at low cost. Here, we revisit the Celldar concept. Global economic downturn has pushed public-sector agencies, transport administrations among them, to push even harder for cost efficiencies. Unfortunately, when it comes to transport safety and efficiency the public sector often has to work up to a cost rather than

Spanish specialist in wireless sensor networks Libelium has launched the Vehicle Traffic Monitoring Platform as part of its Smart Cities solution. The platform is capable of sensing the flow of Bluetooth devices in a given street, roadway or passageway while differentiating hands-free car kits from pedestrian phones. Sensor data is then transferred by a multi-hop ZigBee radio, via an Internet gateway, to a server. Traffic measurements can then be analysed to address congestion of either vehicle or pedestria

The County of Los Angeles is widely known for having among the worst traffic problems and the most road congestion in the US. To combat these problems, the Los Angeles County Department of Public Works decided to deploy a wireless communications system to connect over 1,000 of the most congested intersections so they could dynamically monitor and manage the congestion and reduce commute times.

The Indiana Department of Transportation (INDOT) has deployed an end-to-end Proxim wireless network for a state-wide intelligent transportation system. The network connects traffic and video components over hundreds of square miles throughout the Northwest Indiana and Indianapolis areas.

A new solar-powered, wireless automated rotary drum sign system, manufactured by Skyline Products Traffic Division and currently being deployed in Texas, is being hailed as one of the greenest, least expensive, most flexible means of managing traffic flow.

Travel information services are undergoing a step change as rapid increase in sales of smartphones brings ITS technology to consumers' fingertips. A virtuous circle of expanding capability is under way in traffic and travel information services, promising much for drivers and reduction of road congestion. A recent rapid rise in sales of smartphones has boosted numbers of vehicles carrying GPS enabled devices and so brought expansion of traffic data available for analysis and dissemination. Greater numbers o

Communication Networks (ComNet) has been approved by Code Blue to supply fibre optic media converters and EoVDSL modems (Ethernet over Very High Digital Subscriber Link) for use with its line of IP-compatible phones and emergency call boxes.

ITS Japan's Chairman Hiroyuki Watanabe talks to ITS International about his country's progress with cooperative infrastructures and how the experience gained to date can benefit similar initiatives elsewhere. Japan gave the rest of the world a taste of the cooperative infrastructure future when, in 1996, it went live with the Vehicle Information and Communication System (VICS). Designed to provide real-time traffic information and alerts to in-vehicle navigation systems with the dual aims of increasing safe

ComNet Europe has expanded its Value Line by introducing a costeffective 26-port modular Gigabit Ethernet switch for commercial security applications. The CWGE2FE24MODMS features two 1000FX or TX uplink ports for connecting to the network core. The modules are available with either eight electrical ports that support 10/100TX transmission, or eight user-selectable SFP ports that support 100FX transmission.

Swiss-based U-blox, a leading provider of wireless and GPS semiconductors, has opened a second office in China, located in Shenzhen.
