We were overwhelmed by the submissions, the creativity and playful joy that the community showed in simulating. But let\u2019s start from the beginning:[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_column_text]In 2020, PTV Vissim and PTV Viswalk introduced \u201cattribute modifications\u201d as a new feature. This rather technical term stands for no less than \u201cscripting without a script\u201d, a \u201ccontext generator\u201d to model rare and specific situations for which a dedicated feature might be missing. A first demonstration of the power of attribute modifications was given in this <a href=\"https:\/\/www.youtube.com\/watch?v=pU5FD\" target=\"_blank\" rel=\"noopener\">PTV America Tooltips presentation<\/a> where attribute modifications were used to model PuDo (pick up, drop off) situations at the curbside. Other situations, that may be modelled with attribute modification are:<br \/>\n\ud83d\ude97 Electric vehicles including charging stations<br \/>\n\ud83d\udea7 Opening\/closing barriers<br \/>\n\ud83c\udd7f\ufe0f Car park displays<br \/>\n\ud83d\ude4c\u2026and many more possibilities<\/p>\n<p>As attribute modifications and vehicle\/pedestrian attribute decisions allow you to replace a lot of external scripts, it makes it easy to run, share, debug and understand those models.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text][ultimate_spacer][vc_single_image image=&#8221;14050&#8243; img_size=&#8221;500&#215;500&#8243; add_caption=&#8221;yes&#8221;][\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>The contributors<\/h2>\n<p>We thought it would be fun to find out what else attribute modifications could be used for. So, we announced a contest and therefor asked the community to boost their creativity engine and submit their simulation videos. We called it the <strong>#scriptingwithoutascript<\/strong> summer challenge 2021. We fell in love with each and every single contribution and do not want to hold back all those great submissions.

PTV Vissim provides the flexibility to simulate any complex traffic situations and thanks to UDA and attribute modifications &#8211; your flexibility is extended even further. PTV Vissim can turn visions into reality and can evaluate any scheme possibilities prior to its implementation, which is more realistic and in detail.<br \/>\nI\u2019m much fond of its versatility \u2013 whether it is Urban traffic, Airports, Railway stations, Connected Autonomous Vehicles, Pedestrian-Vehicle interaction, MaaS, or even emission modeling, PTV Vissim will make your life easier. Vissim has even helped me as a stress buster to play around with, by experimenting a lot more during my off-hours.<br \/>\nPTV Vissim is an integral part of my life and I adore it!<\/p>\n<p><strong>Ahmed Saleem (<a href=\"https:\/\/youtu.be\/5cRMrILDfTY\" target=\"_blank\" rel=\"noopener\">busy intersection<\/a>)<\/strong><br \/>\nAs a police communication specialist officer at PSCA, I have worked with different Punjab Safe cities authority Departments. Therefore, I used PTV Vissim mainly in the field of traffic signal planning and coordination. Thanks to my MS Thesis about traffic signal optimization, I have gained profound experience with PTV Vissim, which came to use to improve traffic signals in urban areas.<\/p>\n<p><strong>Mohamed Ali Elsheikhidris (<a href=\"https:\/\/youtu.be\/nXXbR1YJkag\" target=\"_blank\" rel=\"noopener\">3D busy intersection<\/a>)<\/strong><\/p>\n<p>I started learning PTV Vissim software in 2017 from YouTube and files from the PTV Group website. I use my skills to give suggestions and solutions to the Ministry of Infrastructure in Khartoum (Sudan) to solve infrastructural problems I recognized in the city.<br \/>\nI love designing simulations of unusual cases, such as the take\/off and landing of aircrafts or the movement of the Cobra maneuver of the Russian aircraft Sukhoi-37.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text]<strong>Aadil Nawaz, AECOM (<a href=\"https:\/\/youtu.be\/j9sAR_-fZdc\" target=\"_blank\" rel=\"noopener\">F1 Zandvoort<\/a>)<\/strong><\/p>\n<p>Ever since I was introduced to PTV Vissim as a student, I have been fascinated by it. What began as interest during a college project of simulating a simple signalized intersection soon grew into a full-time profession. As a transport planner, with PTV Vissim, I could employ my attention to detail to build some really amazing models- from replicating existing integrated multi-modal networks to testing exciting future mobility systems.<\/p>\n<p>For me, it&#8217;s the visualization and user-friendly GUI of PTV Vissim that make modeling so much fun. Plus the frequent updates from PTV keep me hooked on every year. So this year, I decided to explore PTV Vissim a bit more and simulate an F1 race &#8211; a sport I follow closely. Also with the introduction of the Attribute modification feature, scripting was so convenient that I had to try, and honestly, I had an amazing time simulating the Zandvoort race.<\/p>\n<p>Finally, our dear own <strong>Dr. Thomas Otterst\u00e4tter, Senior Technical Product Manager at PTV, who could not resist the call (<a href=\"https:\/\/youtu.be\/wxBG36vNKmg\" target=\"_blank\" rel=\"noopener\">candy cube crush<\/a>)<\/strong><\/p>\n<p>I like PTV Vissim because: who does not like looking at the visualization and interaction of vehicles, pedestrians, signal controllers etc.? (well at least, if you are into traffic engineering)<br \/>\nPTV Vissim is a quick-to-set-up realistic microscopic simulation, that provides you fast feedback of &#8220;what will happen&#8221; and furthermore it is flexible so that you can basically model and analyze anything you like.<\/p>\n<p><strong>Thanks to everyone who contributed to the #Scriptingwithoutascript summer contest 2021.
