MojoKid writes Dell's Alienware division recently released a radical redesign of their Area-51 gaming desktop. Slashdot: Games ~Created Sat Nov 1 13:21:45 2014Īlienware's Triangular Area-51 Re-Design With Tri-SLI GeForce GTX 980, Tested At the Oculus Connect conference, two of the developers from the team that created the demo share the tricks and tools they used to hit that target on a single GPU. The challenge? Oculus asked Epic to make it run at 90 FPS to match the 90 Hz refresh rate of the latest Oculus Rift 'Crescent Bay' prototype. ![]() The latest demo, built in UE4, is 'Showdown', an action-packed scene of slow motion explosions, bullets, and debris. We’re hoping to transform the current ITE trip generation list of average rates into something that can be filtered into the most applicable data for each particular project.Getting 'Showdown' To 90 FPS In UE4 On Oculus RiftĪn anonymous reader writes Oculus has repeatedly tapped Epic Games to whip up demos to show off new iterations of Oculus Rift VR headset hardware. This is our website to freely share trip generation data under a Creative Commons license. With a stockpile of previously gathered trip generation, and more on the way from our new studies, we have also dovetailed this new process into. In addition, this method automatically accounts for reduced trip generation due to nearby transit facilities as well as bicycle and pedestrian facilities relevant to the study area. This process provides us with a more confident and defendable trip generation rate which should lead toward better studies and more accurate results and recommendations. Establish the trip generation for each similar facility and determine the weighted average rate for use in the study.Set up cameras to capture trip generation at each of the three similar facilities at the same time the study intersection cameras are set.Look for three similar facilities in the surrounding area.In those instances where the project would add significant value, our process includes: Sometimes, given the project schedule or other factors, this option is just not realistic. We’ve taken that suggestion to heart and actively consider whether collecting local trip generation data should be part of our plan. There is another option that is recommended by ITE itself, collect local data. Many land uses only have one or two incomplete studies available for use.Ĭombine these issues with the fact that many land uses have a very large standard deviation (a residential single family home has a standard deviation of 3.7 on a rate of 9.52 trips per dwelling unit, meaning the actual trip generation could be between 5.82 to 13.22 trips per dwelling unit), and it’s easy to see how trip generation is another TIS assumption that could be challenged.Fast casual restaurants like Chipotle fit nicely between the official land uses of Fast Food Restaurant and High Turnover (Sit-Down) Restaurant. An exact land use match is not always possible.Similarly, bike-friendly Minneapolis is different than car-centric Los Angeles is different than transit-heavy Manhattan. Downtown is different than suburban is different than rural. No breakdown of the area where the studies were collected.Is a study of an office trip generation from the 1980s still accurate given today’s environment? My primary issues with using ITE data are: ITE itself says, “At specific sites, the user may wish to modify trip generation rates presented in this document to reflect the presence of public transportation service, ridesharing, or other TDM measures enhanced pedestrian and bicycle trip-making opportunities or other special characteristics of the site or surrounding area.” In other words, take these rates with a grain of salt. If a development is proposed, we estimate the traffic according to ITE data, and follow-thru with the analysis and recommendations.Īs good as this source is, it’s not perfect. It is used by virtually all traffic engineers across the country, including us at Spack Consulting. Composed of thousands of voluntary study submissions over many decades, this book is the most comprehensive list of average traffic per various land uses in the United States. The Institute of Transportation Engineers’ (ITE) Trip Generation Manual could be considered the Bible of Traffic Impact Studies (TIS). Check out the “ Top 6 Ways to Pick Apart a Traffic Study ” for more on the general topic and expect more posts to follow on this subject. Guest Post by Bryant Ficek, PE, PTOE, Vice-President at Spack ConsultingĮarlier this year, I detailed how our standard process for a Traffic Impact Study has several points of assumptions at best or guesses at worst.
