Air Quality & Weather Systems

The University of Michigan Transportation Research Institute has published a new report, Transportation emissions in the context of emissions from other economic sectors: 1990-2014, which examines long-term trends in the contribution of transportation to total greenhouse gas emissions in the United States, in the context of the other sources of emissions (industry, commercial, residential, and agriculture). Also of interest in this study are the relative contributions of various transportation modes, bo

TomTom City, a new traffic portal launched by TomTom, provides live traffic and travel information, including real time traffic status, delay hotspots and road event reporter, for consumers and traffic management experts. TomTom City, which can be found at http://city.tomtom.com, is accessible from any internet enabled computer, tablet or smartphone and provides freely accessible content showing live traffic status and incidents and other driver-based information in cities. This will enable consumers to

Traffic information company Travel for Media has been chosen as traffic data supplier for Radioplayer’s new in-car hybrid radio solution for delivery of traffic services and reduction of driver distraction. Radioplayer Car will be available over the coming weeks as a smart digital upgrade for older car stereos. The system chooses the best platform for any given radio station, delivering it to the vehicle using DAB, FM or streaming, meaning drivers keep hearing their chosen station in maximum quality a

Lufft's VS2k-UMB visibility sensor for road weather stations and traffic control systems, which replaces the VS20-UMB, measures visibility up to 2,000 metres and features an optimised housing alloy that is water resistant even under extreme conditions.

In response to the UK Government’s Fifth Carbon Budget, Freight on Rail says that the Department for Transport must support EU plans to introduce CO2 truck standards to bring HGVs into line with cars and vans. In the UK, HGVs contribute 17 per cent of surface transport’s CO2 emissions even though it only makes up five per cent of road miles driven. Philippa Edmunds, Freight on Rail manager, Campaign for Better Transport said CO2 standards and reduction targets for HGVs are long overdue as truck manufac

The Florida Department of Transportation (FDOT) District Two has selected Parsons to provide final design services for an expansion of FDOT’s freeway traffic management system on I-95 from north of the Jacksonville International Airport to the Georgia state line. The 17-mile project will include various intelligent transportation systems and solutions, including archived data management, automatic vehicle identification, closed-circuit television cameras, dynamic message signs, microwave vehicle detectio

Ticketless parking payment systems specialist Veri-park has launched an advanced vehicle counting technology that can be integrated with Swarco and third-party variable message signs (VMS) to better direct traffic through busy town centres. The system uses loop counting detection at car parks’ entrances and exits, removing the need for onsite hardware. Data is securely transmitted by Veri-park’s new system via the cloud to the VMS to give drivers up-to-date and accurate information on the availability of

Low emission zones and heavy goods vehicles’ access to city centres may at first glance appear attractive but how effective are such controls? Jon Masters reviews emerging trends across Europe. Around 1,700 European cities have implemented low emission zones (LEZs) and in addition some have restricted city centre access for heavy goods vehicles (HGVs). Even those that restrict HGV access, such as Paris and Rome, allow exemptions at certain times and for particular classes of vehicle. But with what effect?

Messagemaker has developed a new electronic speed reduction safety sign, which uses the latest LED technology and is fully programmable to initiate a temporary 20mph speed limit during school arrival and departure times, using 3G data modems to remotely set sign parameters and for retrieval of collected speed data. The signs can also be configured to revert to vehicle activated speed signs outside of the core school times.
