« Tesla Q1 revenue more than doubles on record deliveries; losses up | Main | Four China OEMs select Efficient Drivetrains for PHEV systems for buses » ABB will provide two fast-chargers for Scania electric buses in Östersund, Sweden. The chargers are based on OppCharge, an open interface for the automated charging of electric buses from any manufacturer, and use a pantograph on the infrastructure to connect the bus to the charging point. With tests set to start in the final quarter of 2017, the two ABB HVC300P fast-chargers will charge six fully-electric Scania buses. The trials will be carried out in collaboration with public authorities, including the City of Östersund, the municipality of Krokom, the Region Jämtland Härjedalen’s Public Transport Authority, the publically owned energy supplier Jämtkraft and the Swedish Transport Administration. The buses will be operated by Nettbuss, a subsidiary of the Norwegian State Railways, NSB, which is the second-largest bus operator in the Nordic countries. The two charging stations will be built at both ends of the 14-kilometer major bus line, powering six buses. With 10-minute charging, the buses will run every 15 minutes, making 100 journeys each day. ABB’s fast-chargers are connected to the cloud for remote diagnostics and management, and receive over-the-air software upgrades to ensure maximum availability. Östersund Kommun issued separate tenders for the buses and their charging infrastructure. This was made possible by the OppCharge interface, which is compatible with a range of bus models, including electric hybrids. Östersund was presented with the European Mobility Week Award in 2015 in recognition of the council’s work providing sustainable transport options in the city. This project with Scania and ABB will extend their work in sustainable transport. "The introduction of battery electric buses here is really exciting," says Project Manager Anne Sörensson from the City of Östersund. "They will contribute to our aim of achieving fossil-free transport by 2030." The cold climate of Östersund makes it the optimal testing ground for ABB's fast-chargers, which are designed to be reliable in extreme environments.

Malmbanan, the Swedish Iron Ore Line, runs through rough terrain including high mountains, peat, terraces situated on fjords, and numerous short bridges and culverts. The area is sub-arctic and mountainous, with a sharp gradient between the part with a maritime climate and that with a continental climate. Global warming and new climate conditions are increasing the risk of slab and snow avalanches. A cost-benefit-risk analysis, dealing with slab and snow avalanches, high spring temperatures with fast snow melting, high water levels and heavy rainfalls, was performed in 2001. A number of at-risk sections along the track were identified and some of the risks were later addressed with changes in the infrastructure and changes in train operation during bad weather conditions. During the past 10 years, the various actions taken have been continuously improved. An evaluation based on operational data shows a lower risk of trains running into hazard areas and better control of slab and snow avalanches. Other improvements are better control and monitoring of rock falls and a lowered risk for trains operating during bad weather conditions. The technical systems in use consist of instrumented arrays of poles placed along the track to indicate avalanches. Bridges have been built to permit avalanches to pass under the railway and artificial tunnels have been designed and constructed to allow avalanches to pass over the railway. Rock fall nets have been put into service and professional avalanche inspection teams have been used for risk evaluation during high-risk weather conditions. © Trafikverket 2012.

When targeting a society free from serious and fatal road-traffic injuries, it has been a common practice in many countries and organizations to set up time-limited and quantified targets for the reduction of fatalities and injuries. In setting these targets EU and other organizations have recognized the importance to monitor and predict the development toward the target as well as the efficiency of road safety policies and interventions. This study aims to validate a method to forecast future road safety challenges by applying it to the fatal crashes in Sweden in 2000 and using the method to explain the change in fatalities based on the road safety interventions made until 2010. The estimation of the method is then compared to the true outcome in 2010. The aim of this study was to investigate if a residual of crashes produced by a partial analysis could constitute a sufficient base to describe the characteristics of future crashes. Result show that out of the 332 car occupants killed in 2000, 197 were estimated to constitute the residual in 2010. Consequently, 135 fatalities from 2000 were estimated by the model to be prevented by 2010. That is a predicted reduction of 41% compared to the reduction in the real outcome of 53%, from 332 in 2000 to 156 in 2010. The method was found able to generate a residual of crashes in 2010 from the crashes in 2000 that had a very similar nature, with regards to crash type, as the true outcome of 2010. It was also found suitable to handle double counting and system effects. However, future research is needed in order to investigate how external factors as well as random and systematic variation should be taken into account in a reliable manner. © 2015 Elsevier Ltd.

Fibre reinforced polymer (FRP) bridge decks have become an interesting alternative and they have attracted increasing attention for applications in the refurbishment of existing bridges and the construction of new bridges. The benefits brought by lightweight, high-strength FRP materials to these applications are well recognised. However, the sustainability of bridge concepts incorporating FRP decks still needs to be demonstrated and verified. The aim of this paper is to bridge this knowledge gap by examining the sustainability of these FRP solutions in comparison with traditional bridge concepts. An existing composite (steel-concrete) bridge with a concrete deck that had deteriorated was selected for this purpose. Two scenarios are studied and analysed; the total replacement of the entire bridge superstructure and the replacement of the concrete deck with a new deck made of GFRP. The analyses prove that FRP decks contribute to potential cost savings over the life cycle of bridges and a reduced environmental impact. © 2013 Elsevier Ltd. All rights reserved.

Electric Road Systems (ERS) are already being demonstrated on public roads in Sweden. (Earlier post.) Now, a new project in Sweden, “Research and Innovation Platform for Electric Roads”, will explore how to make the step to large-scale operation along with the supporting business ecosystem as well as technical issues such as the standardization of interfaces. Viktoria Swedish ICT is coordinating the project and us working together with the research partners Chalmers University of Technology, KTH Royal Institute of Technology, the Norwegian Institute of Transport Economics (TØI), and the Swedish National Road and Transport Research Institute (VTI); with the industry partners Fortum, Profu, Scania, Vattenfall, and Volvo Group; as well as with the deployment proposals managed by Airport City Stockholm, Region Gävleborg, and Region Kalmar. Swedish ICT is a group of research institutes engaged in information and communications technology research and development. The institutes within Swedish ICT conduct research and development in several key areas, ranging from sensors and actuators, communication networks and data analytics to visualization, interaction design and service development. Viktoria Swedish ICT is the institute focused on sustainable mobility. The various parts of electric road systems have been developed in several research projects over quite some time. Technology demonstrations are ongoing along the E16 road at Sandviken and being prepared between Arlanda Airport and Rosersberg Logistics area. Our goal is to gather and build knowledge about ERS in order to answer some of the considerable questions that remain. The project has been granted SEK19 million (US$2.2 million) in funding from the Swedish Program for Strategic Vehicle Research and Innovation (FFI) and the Swedish Transport Administration. An industry contribution of SEK8 million ($930,000) gives a total investment of SEK27 million (US$3.1 million) for a term ending in 2019. Successful introduction of ERS will require a supporting and strong innovation system. The purpose of the project is to strengthen the Swedish and Nordic research and innovation resources by building a joint knowledge base in cooperation between institutes, universities, authorities, industry, and demonstration sites. The result will include clarification of the socio-economic conditions, benefits and other effects of ERS from different actors’ perspectives. Various implementation strategies will be evaluated and success factors will be identified. The project will establish an international cooperation and provide a basis for dialogue on future standards and regulations. The project will work closely with ongoing ERS demonstrations in Sweden. The industry is participating as partners in the project and as members of an extensive reference group. We are about to secure the technical solutions needed for electric roads and electric vehicles. In order to reach a full scale implementation a series of other questions needs to be solved, e.g. on business models and electrical infrastructure. This research and innovation platform is important since it unites actors from different fields in order to find the needed solutions.

Volvo is planning to outperform its own energy-saving Hyper Buses by building a road that can wirelessly charge city buses in operation. The company is working with the city of Gothenburg and the Swedish Transport Administration to use a technology called inductive charging and build an electric road that can transfer energy directly from the grid to the battery of a vehicle while the vehicle is passing over that road. The company plans to test out this technology on Gothenburg's public transport. "Vehicles capable of being charged directly from the road during operation could become the next pioneering step in the development towards reduced environmental impact, and this is fully in line with our vision of becoming the world leader in sustainable transport solutions," says Volvo Group's executive vice president for corporate sustainability and public affairs Niklas Gustavsson in a press release. "Close cooperation between society and industry is needed for such a development to be possible and we look forward to investigating the possibilities together with the City of Gothenburg," he adds. Volvo has been providing energy-sipping gas-electricity Hyper Buses, short for Hybrid and Plug-in Extended Range Buses, for several years. The city of Gothenburg already has three of these buses in operation. The next step is to update these buses, which currently take five to eight minutes to recharge at the charging stations, so that they don't have to stop to be recharged. This would reduce the time it takes for charging and increase the distance the buses can travel without running out of power. Volvo has yet to submit a formal proposal to the Swedish Transport Administration. This will include details on how it plans to construct its vehicle-charging road and develop public transport vehicles suitable for testing. By 2015, Volvo hopes to finish the construction of ElectriCity, its test road that will span 300 to 500 meters along a bus line between Chalmers and Lindholmen in central Gothenburg. In 2013, Volvo also announced testing for inductive charging after it had built a quarter-mile road with two power lines attached to the surface. A year before that, it also began testing at a facility just outside Gothenburg, but the company said its current technology did not allow inductive charging for long-distance trucks and buses, and that it still needed to conduct "a great deal of research" before it can roll out its electric roads for public use.

« First minimal synthetic bacterial cell designed and constructed by scientists at Venter Institute and Synthetic Genomics; 473 genes | Main | CARB seeks new $366M vehicle testing and research facility at UC Riverside » At the end of this month, six automated truck platoons—representing 6 different truck OEMs and their partners—will leave several European cities of origin and drive along public roads, targeting arrival at the APM Terminals, Maasvlakte II, Rotterdam on 6 April. This European Truck Platooning Challenge represents large-scale testing of cross-border automated truck-platooning; its aim is to bring platooning one step closer to implementation. Truck Platooning involves trucks driving a short distance apart using automated driving technology; platooning offers benefits in terms of fuel consumption and CO emissions, safety and the flow of traffic. The Truck Platooning Challenge will demonstrate that a second vehicle is technically capable of automatically following the combination ahead using wireless communications, radar and cameras. The truck platoons will all depart from their home base or production location. Scania has the longest route in the European Truck Platooning Challenge—more than 2,000 km (1,243 miles), crossing four borders. The teams from the six brands will only platoon on motorways in normal traffic conditions. Local conditions will dictate whether or not they platoon for the whole route. Over the past six months there has been intensive and multidisciplinary cooperation/teamwork to realize this new form of mobility. The network involved governmental, road and other authorities from the participating countries (Belgium, Denmark, Germany, Finland, the Netherlands and Sweden), truck manufacturers, umbrella organizations (ACEA, CEDR, CLEPA, EReg and IRU) plus a range of common interest groupings and consumer bodies. DAF. A consortium of DAF Trucks, TNO, NXP and Ricardo is uniting under the name EcoTwin. Within the context of the EcoTwin project, it has already been demonstrated that the second vehicle is also capable of steering automatically. However, the emphasis during the Truck Platooning Challenge will be on autonomous acceleration and braking. In this regard, the planned distance between both combinations is 0.5 seconds, which at a speed of 80 km/h (50 mph) approximates to a distance of 10 metres (10.9 yards). One novel aspect of the EcoTwin combination is the advanced Wifi-P connection, developed by NXP and specially designed for automotive applications. The rapid speed of the communication enables both DAF trucks to drive even closer together. Furthermore, Wifi-P allows the drivers of the EcoTwin combinations to communicate with each other while driving. Everything that the driver in the first truck sees in front of him is projected onto a screen in the second truck (‘See Through’). By reducing the gap between truck combinations as far as possible and making the most of slipstreaming, fuel savings of up to 10% can be achieved in future, along with equivalent reductions in CO2 emissions. Furthermore, Truck Platooning will further enhance traffic safety, thanks to the combination of Wifi, radar and camera systems. Another benefit is the further improvement to the flow of traffic, because platooning trucks will not overtake each other. Moreover, technologies are being developed that will enable passenger vehicles to join the traffic or leave the motorway safely and responsibly. Daimler. Daimler is participating in the challenge with Mercedes-Benz Actros Highway Pilot Connect trucks. (Earlier post.) Daimler first presented Highway Pilot in July 2014, in the Mercedes-Benz Future Truck 2025 study, followed by the first public road authorization for an autonomously driving truck in May 2015, for the Freightliner Inspiration Truck. Compared to the Highway Pilot, Highway Pilot Connect has the additional technical function for electronic vehicle docking. Communication between vehicles is made possible by an onboard telematics platform. A specific V2V (vehicle-to-vehicle) communication module using a special WiFi standard reserved exclusively for automotive enables direct data transfer between the trucks. Highway Pilot Connect uses this for a constant exchange of information with other trucks and the environment. Because of their technology, all the members of such a platoon continue to be autonomously driving trucks. They are able to maintain their direction independently of the vehicle ahead, and thanks to their combination of linear and lateral guidance, they can react to unexpected situations at any time. This also applies if other vehicles cut into or leave the platoon’s space. In this case the vehicle can smoothly disengage from the platoon and continue alone in autonomous mode. The driver does not need to intervene. MAN. The platoon only forms on the motorway following confirmation from both drivers. The longitudinal control of the vehicle behind is activated and slowly reduces the distance to the vehicle in front down to the platooning distance. The two trucks are now synchronized and travel at a defined distance, with continuous monitoring of sensor readings and the functioning of the vehicle communication. The platoon journey can be ended at any time by either driver via an un-coupling signal or by taking control of the driving. If possible, in the interests of fuel efficiency, the distance is adjusted to the legally prescribed distance without interventions in the brake system. Platoon journeys with a reduced minimum gap of less than one second apart require secure vehicle-to-vehicle communication. Key driving functions such as accelerating and braking torques are transferred instantaneously from the vehicle in front to the vehicle behind. When supported by further sensors, this enables synchronous slipstreaming for both vehicles with a positive impact on fuel efficiency. MAN uses a standard developed in the Car-2-Car Communication Consortium for automotive WLAN (ITS-G5). This technology features instantaneous and direct communication, thus fulfilling the requirement for networked vehicles. Scania. Scania will send off three extra-long trucks on 29 March. For the leg between Södertälje and Malmö in Sweden, the Scania truck and trailer combinations will be driven with an extra trailer, taking their total individual lengths to 32 meters. Volvo. The Volvo Group will participate by driving three trucks in a platoon from Gothenburg to Rotterdam in the Netherlands via Denmark, Germany and Belgium. Volvo, in cooperation with the Swedish Transport Administration and the City of Gothenburg, will arrange a seminar in Gothenburg in conjunction with the start of the journey to address the potential to enhance the efficiency of transportation through platooning and autonomous driving. A similar seminar will be arranged by Volvo Trucks in Brussels. EU Truck Platooning Challenge is an initiative of the Ministry of Infrastructure and the Environment within the framework of the EU presidency.
