Action Steps to Improve Your City

As we begin 2017, HAKS would like to share Curbed New York’s suggestions on initiatives we can launch to improve our cities.  We have culled a small number from the list; you can access them all at 101 Small Ways You Can Improve Your City. Continue Reading…

Airborne Trains Traveling on Strings

Unitsky String Transport (UST) is a transportation system developed by Russian inventor Anatoly Unitsky as a railway consisting not of steel tracks bolted to ties but rather elevated high-tension concrete- and steel-enveloped wires strung between towers, thereby offering rails that can traverse uneven terrain, forests, or water without the prohibitively expensive infrastructure required by conventional transit systems. Furthermore, UST can traverse obstacles in a straight line, thereby obviating the need to circumnavigate impediments or build switchbacks and considerably reducing the distance between two points.

Unitsky began developing the concept back in 1977. His design uses high-tension steel wires inserted into a concrete-resin core and enveloped by steel shells and elevated from three to 30 meters from the ground (or potentially even higher, if the terrain necessitates it). While this might sound like a conventional ropeway (like a chairlift or the Roosevelt Island Tramway), it differs in its much higher cable tension with sag of less than an inch between support posts, allowing vehicles to travel along the wires with a minimum of drag and at speeds, according to Unitsky, of between 200 and 300 mph. “In fact,” according to newatlas.com, “it’s more accurate to look at a UST track more or less as a tiny pre-stressed concrete bridge, built for a fraction of the cost of a ground rail system or even a motorway.” Continue Reading…

Pedestrian incidents increase by nearly 40 percent in the early evening hours compared to crashes outside the fall and winter. Lower visibility during the dark hours of the colder months leads to twice as many crashes involving turns.  In 2015, the year with the fewest traffic fatalities in New York City’s recorded history, 40 percent of pedestrian fatalities occurred after October 1.

Engineering the Cities of the Future

downtown-nySmart Cities use data, information, and communications technology to streamline urban infrastructure activities such as transportation and traffic management, water supply networks, waste and wastewater management, and power plants to improve the lives of their residents. Smart Cities not only present challenges to the A/E industry, but opportunities as well. Smart buildings can utilize building management systems to save energy; transportation systems designed for autonomous vehicles can be designed with a streamlined footprint and more effective flow of traffic; municipal management systems can incorporate sustainable materials and green infrastructure; and affordable and efficient ground transportation can increase convenience and quality of life.
