Jammed Demo

You are a traffic engineer. Draw roads and bridges, connect growing districts, and watch your city come alive. Design efficient interchanges and avoid traffic jams.

<h2 class="bb_tag" >Draw roads. Run the simulation. Fix the traffic.</h2><p class="bb_paragraph" >Draw roads and bridges, connect growing districts, and watch your city come alive. Design efficient interchanges and prevent your city from becoming Jammed.</p><h2 class="bb_tag" >Draw Your Road Network</h2><p class="bb_paragraph" >Place districts and draw one-way roads and bridges by hand. Every connection changes how traffic moves through your city.</p><p class="bb_paragraph" ><span class="bb_img_ctn"><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4831170/extras/d8926d375752fae0cb6f186a04b90366.poster.avif?t=1782276663" width=640 height=240 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4831170/extras/d8926d375752fae0cb6f186a04b90366.webm?t=1782276663" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4831170/extras/d8926d375752fae0cb6f186a04b90366.mp4?t=1782276663" type="video/mp4"></video></span></p><p class="bb_paragraph" ></p><h2 class="bb_tag" >Watch Traffic Come Alive</h2><p class="bb_paragraph" >Start the simulation and watch hundreds of vehicles travel through your network in real time.
