superfast charger for buses in Barcelona

Posted On Tuesday, 29 November 2016

The first ultra-fast pantograph charging point for electric buses in Spain has been recently installed in Barcelona.

This initiative is part of the project promoting urban electric mobility ZeEUS (Zero Emission Urban Bus System), funded by the European Union an involves ten cities in Europe. This project started in 2013 and is expected to be completed in April 2017.

The ultra-fast charger recharges the battery up to 80% in an estimated time of 5-8 minutes. The battery is fully charged at night, when the buses are in the depot, taking up to four hours.

pedestrians are most likely to be involved in road collisions during autumn

Posted On Friday, 18 November 2016

According to a new analysis carried out from the statistics provided by the Local Authorities in the NE of England, pedestrians most likely to be involved in road collisions during weeks leading up to Christmas.

Almost a third of pedestrian accidents happen between October and December, with 7am to 9am and 3pm to 6pm the most prevalent times of day. Most pedestrian casualties (86%) happened on 30mph (50 km/h) urban roads.

Children account for a high percentage of the casualties, with boys aged between 11 and 12 the most likely age group to be injured. However, almost a quarter of adult pedestrian casualties are found to have been impaired by alcohol – with this figure rising sharply in collisions that occur between 10pm and 6am.

first commercial train powered by hydrogen

Posted On Monday, 14 November 2016

Germany debuts zero-emissions train that releases only steam, being powered by hydrogen. The train will open to the public in December 2017, and testing will continue before that time.

The iLink can travel almost 800km (500 miles) per day up to 87mph (140 km/h) using lithium ion batteries (carrying 300 passengers). Batteries are powered by a hydrogen fuel tank on the roof of the train, which is similar to any other electric train, but does not need any catenary or pantograph.

The main downside at the moment is that the production of "cheap" hydrogen usually involves the use of fossil fuels such as oil, although there are other more or less efficient and costly methods.

the shortest international air route in the world is now on operation

Posted On Friday, 11 November 2016

The shortest international regular air route covers a distance of 21 kilometers, with an official duration of the flight of 20 minutes, although it takes only eight minutes to travel the distance between the two cities. the flight, from San Galo / Altenrhein in Switzerland to Friedrichshafen in Germany crossed the Austrian border and it is actually the first stretch of a route that continues Cologne (Germany). Some other crazy routes are described at Fronteras Blog.

Related: brief explanation about the meaning of the most common markings painted on the tarmac of the airport runways:

The numbering names the track corresponds to its orientation to magnetic north (the direction given by the compass). Parallel lines in the end of the runway usable indicate the width of the track. Four bars means that the track is about 18 meters wide and 8 bars example -case warn that the track is 30 meters wide. A series of thick, short lines placed at each side of the runway center provide guidance (approximately) the pilot to touch the runway on landing.

Canada to make rear-view cameras mandatory

Posted On Tuesday, 8 November 2016

Canadian Minister of Transport Marc Garneau has proposed new regulations that will require rear-visibility systems on all new vehicles sold in Canada from May 2018 to provide all new car owners with improved visibility to spot people and objects behind a vehicle when they reverse; "this helps children be seen and provides Canadians with one of the best safety technology systems to reduce back-over collisions," Transport Minister Marc Garneau said in a statement.

It estimates that such accidents killed 27 people and injured more than 1,500 from 2004 to 2009.

"The objective of this proposal is to align the Canadian and United States* safety regulations, to provide Canadians with the same level of protection under the law related to back-over crashes offered to residents of the United States and to satisfy vehicle manufacturers' call to eliminate regulatory differences between Canada and the United States," Transport Canada said.

*The United States made a similar announcement in 2014, with a 2018 deadline for compliance.

optimal walking and cycling speeds to reduce air pollution inhalation

Posted On Friday, 4 November 2016

According to a new University of British Columbia (UBC) research, cyclists should be riding at speeds between 12 and 20 km/h on city roads, while pedestrians should be moving at 2 to 6 km/h to minimize their inhalation of air pollution while still getting the health benefits of exercise.

"The faster you move, the harder you breathe and the more pollution you could potentially inhale, but you also are exposed to traffic for a shorter period of time."

Ideal travel speeds were at 13 and 15 km/h for female and male cyclists in the 20-60 age group.

This research explores the same problem recently reported here, where it was analysed the maximum number of weekly hours riding a bike before the harm due pollution was worse than the benefits derived from exercise.

new initiatives promoting road safety @ITEhq @ITF_Forum @fia

Posted On Wednesday, 2 November 2016

The International Transport Forum (ITF) and Fédération Internationale de l’Automobile (FIA) launched Safer City Streets, the new global traffic safety network for liveable cities.

Cities provide data to the Safer City Streets database via a questionnaire and in return have free access to data from peer cities, thus allowing comparisons. The ITF manages the data collection and validation, analyses the data and administrates the network. Safer City Streets will go beyond the database by establishing a network of experts, whose goal is to exchange knowledge and learn from each other and their respective cities. Safer City Streets builds on a 2013 pilot project with nine cities from Europe and North America that shared data on crashes, population, mobility and traffic.

Meanwhile in the US, the Institute of Transportation Engineers (ITE) has joined several US entities (see note) to launch the Road to Zero coalition with the goal of ending fatalities on US roads within the next 30 years.

ITE has also launched the Vision Zero Task Force initiative to advance the goals of the Vision Zero and Towards Zero Deaths movements, which goes hand-in-hand with the Road to Zero coalition's goals.
