Announced for PC","summary":"Software engineer Sahaj Jain announced Highways \u0026 Co., a PC (Steam) simulation game focused solely on road traffic networks. Players build roads, observe usage, and correct congestion without constructing buildings. The game offers 10 road types, adjustable lanes, 7 height levels, and railways. Playtesting is expected to begin within August.","whyItMatters":"The game strips city-building down to its traffic network layer, appealing to players who find road optimization the most engaging part of the genre.","webCardHtml":"\u003cp\u003eHighways \u0026amp; Co. drops the city and keeps the congestion. Sahaj Jain, a software engineer at Vercel, announced the road traffic simulation game on August 20 for PC via Steam, with Japanese display planned.\u003c/p\u003e\u003cp\u003eThe game removes building construction entirely. Landmarks appear only as colored signs, leaving roads and railways as the main focus. Players lay roads, watch traffic use them, then fix the jams and wasted capacity that appear. The loop repeats until the network runs clean.\u003c/p\u003e\u003cp\u003eTen road types are available, from country roads to four-lane highways. Lanes can be asymmetric per direction, and roads can cross in three dimensions using cuts, tunnels, and viaducts. Traffic lights, stop signs, and roundabouts are included, and railways can meet roads at level crossings or pass over them.\u003c/p\u003e\u003cp\u003eJain said he played many city builders but always ended up focused on road networks, so he built a game around that. Playtesting is expected to start within August.\u003c/p\u003e","blueskyPost":"Highways \u0026 Co. strips city-building to pure traffic flow, making congestion the only metric.

Sahaj Jain strips out zoning, population, and buildings, leaving only road networks and congestion. The design assumes traffic problems are purely geometric, a stance that ignores how land use generates demand.
