London tests LED crosswalk that responds to real-time conditions. Dive Brief: A "smart crossing" prototype that uses cameras, sensors, computer programming and a large LED screen installed in the ground — dubbed "Starling Crossing" — has been revealed in London, according to Wired and others.The crosswalk improves safety by adjusting its road markings in real-time, in response to the presence of vehicles, pedestrians and cyclists.

London tests LED crosswalk that responds to real-time conditions

A visible crosswalk doesn't appear until a pedestrian stands near it and it's safe to walk. Markings disappear once everyone has crossed.The technology tracks and anticipates movements, while learning over time so it can better and more quickly process information and respond to changing stimuli. Dive Insight: While the system is high-tech and connected, wide-spread installation may not happen as rapidly as simply painting a crosswalk on the street. The LEDs have other safety benefits as well, including the ability to respond to commands in less than one-hundredth of a second. Top image credit: Direct Line. HydroSTON Permeable Paving.

This surfacing is the soft rubberised safety flooring commonly associated with establishments such as playgrounds, play areas, nurseries and parks. Impact absorbing wet-pour surfaces are known under many names for example rubber tarmac, bouncy flooring, soft pour surfacing and soft safety surfaces. You can fill in the contact form on this page if you've got any questions about costs for installing safety flooring.

We'll reply with some product sheets and a quote for the work as well as professional advice regarding the whole process. Wet Pour Rubber Installation Near Me The surface is created using a two layer system; the bottom layer is known as the shock pad layer or rubber base layer and is made up 2-6mm SBR rubberised granules that are mixed with a specially formulated polyurethane binder before being laid onsite. What is Wet Pour? In Situ Installed Wet Pour Safety Surfacing. Resin Bonded Gravel Surfaces. We install resin bound gravel which is a porous paving system that is available in a wide range of natural aggregates.

Resin Bonded Gravel Surfaces

Creating resin-bound gravel involves the process of encapsulating natural aggregate within a polyurethane resin that, when screeded, provides a smooth textured, aesthetically pleasing, hardwearing surface that is low maintenance and resistant to cracking. The ideal surface for the system to be installed upon would be a macadam base as it's SUDS (Sustainable Urban Drainage System) compatible meaning it's open textured and porous allowing water to drain correctly. We offer a variety of designs for resin bound stone which come in a range of colours to suit your preference. Porous Resin Bound Paving Pathway Surfacing London by SportsAndSafety on DeviantArt. Permeable Pavers - Tip of the Mitt Watershed Council. Recycling of Asphalt Mixes and Use of Waste. Recycling of Asphalt Mixes and Use of Waste EAPA as a responsible industry organisation taking into consideration the current trends towards: * sustainable development, whilst impact on the environment is minimized, * optimizing the use of natural resources, * increasing restrictions on the dumping of reusable material, possibly leading to a ban on their disposal into landfills, * potential economic incentives to encourage the recycling and re-use, will promote increased recycling of asphalt mixes and assess for suitability, alternative sources of recyclable material.

Recycling of Asphalt Mixes and Use of Waste

These materials will be combined along with technical innovation and enhanced quality management systems to produce an improving product that retains the potential for approaching 100% re-usability. The European asphalt industry takes care of the environment and feels responsible for its product during its whole lifetime. Advantages of Asphalt. Kraton Corporation. Highly modified asphalt, HiMA is a tool that can be used to solve a variety of problems in asphalt pavements.

Rubberized Asphalt Concrete (RAC) Home Page

Rubberized asphalt concrete (commonly known as RAC) is a road paving material made by blending ground-up recycled tires with asphalt to produce a binder which is then mixed with conventional aggregate materials. This mix is then placed and compacted into a road surface. There are two primary types of binders for RAC, asphalt-rubber and terminal blend. Note: Definitions to many terms are displayed as green links to the RAC site glossary.

Federal grants for infrastructure upgrades and transportation are nothing new.

5 Takeaways from Federally Administered Next-Gen Transportation Programs for Modernizing Infrastructure

On the contrary, the federal government has largely been in charge of the nation’s infrastructure due to its jurisdiction on interstate commerce and ability to coordinate state agencies to follow uniform codes and standards. With recent developments and grant programs, this model seems to be evolving. During Anthony Foxx’s tenure as secretary of transportation, he and the U.S. Department of Transportation (DOT) initiated the Smart City Challenge, which put up $40 million of federal funds and an additional $10 million from Paul Allen’s Vulcan Inc. to the mid-size city that created the best strategy that integrated next-generation transportation systems.

As the former mayor of Charlotte, N.C., Foxx helped identify where innovation was taking place while creating a climate for sharing best practices and distributing the benefits. Inverting the Top-Down Approach “Generally we grant money to the states,” said Dowd. How green infrastructure investments can create commercial property value. A new publication from my colleagues in NRDC’s water program shows how green infrastructure practices – integrating nature strategically into urban environments to control runoff and enhance other environmental values – can help advance the bottom line for the commercial real estate sector.

How green infrastructure investments can create commercial property value

It is a highly illustrative and well-documented report. In particular, The Green Edge: How Commercial Property Investment in Green Infrastructure Creates Value (disclosure: I reviewed and commented on a pre-publication draft) draws from all available published material to capture the multitude of quantifiable financial benefits that green infrastructure investments can generate for commercial property owners and their tenants.

Green infrastructure can include trees, rain gardens, porous pavement, rainwater harvesting cisterns, bioswales, and related techniques. In a blog post published earlier this week, my friend and colleague Larry Levine adds detail to the report’s main findings: Related posts: 2013 Report Card for America's Infrastructure.

What is the value to America’s economy in the long term if we invest in our infrastructure today? The Race to Rebuild America's Infrastructure. Crumbling America1 Full Documentary. A World Without Humans,The Aftermath Of Mankind Leaving This Planet. A Gorgeous First-Person Video Game About Infrastructure Is Now Out on Steam. Take the brooding beauty and dystopian, Soviet-flavored setting of “Half-Life 2”—but remove the weapons and monsters—and you got yourself “INFRA,” a video game about fixing a crumbling city before everything goes to hell.

The first-person nonshooter will not appeal to everyone. The action begins in, of all places, a boardroom discussion—a narrative decision the game seems to instantly regret, because you get a pop-up option to “Skip meeting.” “Look, just text me the memos, I want this over with as soon as possible,” your character growls. Yet you might spend the next 7 minutes trying to find the dang exit of your office building, as did a guy who recorded the below play-through video. (He then fell off a ledge and died.) As for the plot, you are “Mark,” an engineer tasked with saving the infrastructure of a once-profitable, now badly degraded Baltic mining city.

It might sound tame, but the unique mission and lovely, atmospheric graphics might appeal to a wonky slice of gamers. Fix a Crumbling Baltic City in the First-Person Video Game INFRA. Tell me if this intro to the first-person video game “INFRA” doesn’t get your adrenaline gushing: We put you into the shoes of a structural analyst.

Nothing more than a quiet desk jockey assigned to survey some routine structural damage. Quickly though, your mission turns from a mundane trek to a fight for survival. Your tools are simple: the camera around your neck and the wits to navigate a virtual labyrinth of debris. How you tell your story is your choice, will you have the commitment to finish your duty, or will you ignore all else but the preservation of your own life? OK, so the premise isn’t as action-packed as swinging across a floating, racist city in “Bioshock Infinite” or no-scoping ultranationalist terrorists in “Modern Warfare 3.”

It was actually America’s dangerously outdated roads and levees that inspired Loiste Interactive’s Oskari Samiola to create “INFRA.” Have a look at some more settings, and if you want to support “INFRA” head on over to Indiegogo. 2013 Report Card for America's Infrastructure. 2013 Report Card for America's Infrastructure. Methane. Saturated hydrocarbon with formula CH4 Methane ( or ) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, although capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure.

Naturally occurring methane is found both below ground and under the seafloor, and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. Detroit A City In Decay.
