A Green Light for Muni Customers By Stephen Chun Have you ever been on a Muni vehicle and realized that if the light had only stayed green for just a few more seconds you wouldn’t have been trapped at a red light?  SFMTA’s Connected Corridor Pilot  approached this problem with a new state of the art solution.   Most signals in San Francisco do not have sensors to detect vehicles at an intersection. However, through a grant from the U.S. Department of Transportation, our project team was able to test an advanced technology for signal timing based on who is present at an intersection. In this way, transit platform and traffic signal sensor data can be used to activate signal timing adjustments, responding to traffic conditions in real time. These adjustments provide more opportunities for transit vehicles to make it through intersections on a green light.    The project team turned on the adaptive signal timing program during several days in July and August 2021, with traffic enginee

Watch San Francisco’s Bike Network Bloom By Eillie Anzilotti From just a few stretches of scattered lanes in 2013, San Francisco’s protected bike network now stretches like a green web connecting more and more of the city. See how much has changed over the last eight years:   In just the blink of an eye, San Francisco has become one of the most bike-friendly cities in the U.S. To date, San Francisco has 464 miles of bikeways, including: 42 miles of protected bike lanes 78 miles of off-street paths and trails 21 miles of buffered bike lanes 139 miles of striped bike lanes As we’ve expanded the network of safer bicycle routes through San Francisco, more people are choosing to ride bicycles for recreation and transportation every year. Since 2006, travel by bicycle has grown by 184 percent citywide. Before the COVID-19 pandemic, bike counts hit an all-time high: in 2019, approximately 52,000 bicyclists were observed at 37 locations during peak periods, a 14 percent increase

Show HN: A *really* easy to use C++ server-side Node.js Monero miner Hi Guys. Last weekend I bootstrapped a little side project. Its a really really easy to use NPM module, that loads XMRIG (c++) and starts mining.I just released the first version on the NPM registry. It can be setup to only run on production machines (NODE_ENV production). It can be used on CI/CD setups where the machines do nothing for a long period of time it can be used on simple webservers that do not have a lot of traffic. Etc etc It writes output to a log file, to the console, or totally ninja mode and no output is given. It even includes a simple webview to monitor stats. By default its set to 'low priority', so the machines doesn't freeze up! :) Let me know if anyone is planning on using it or has any problems, thanks! https://ift.tt/3p4dkos https://ift.tt/3Ec87Sc November 29, 2021 at 10:33PM

Show HN: Security Camera Lens Calculator ( www.jvsg.com/online/ ) We created Security Camera Lens Calculator with 3D graphics(WebGL) and a built-in camera database. It is a web app (Javascript+React) that runs in a browswer or on a tablet or a smartphone. It took our team more than 1 year to complete the calculator. Calculator functions: - calculate pixel density (PPM/PPF) - clearly see dead zones in 3D - check DORI zones (detection, observation, recognition, identification) based on pixel density calculations and IEC and EN 62676 standard. - calculate lens focal length - load a floor map to see camera coverage on your plan - over 9,000 video surveillance camera models embedded in the CCTV Lens Calculator. - 12 languages supported. Today we launched our Security Camera Lens Calculator also on ProductHunt. We would love to get some feedback. Particularly from people using it to solve real world problems.

From Elkton to Green, the Evolution of Muni’s Oldest Rail Yard By Jeremy Menzies In part two of our two-part series on one of the city’s oldest transit properties, we bring you the history of Muni’s Green Division. Green Division, also known as Muni Metro Center, has served as the primary maintenance and repair facility for our rail fleet for over 40 years. Construction began on Green Division in 1975. This new rail facility would replace Elkton Shops, which was built in 1907. The new shops were built in two phases, first the shop building then the rail yard. This 1976 photo shows major excavation and concrete work underway for the main shops building of Green Division.  At far left is Elkton Shops built in 1907 by the United Railroads Company. In phase one of the project, crews demolished the bus yard occupying the eastern half of the property and built a massive new building that would house repair and maintenance shops for a new fleet of Muni rail vehicles. This phase took ab
