Traffic Architect

Traffic Architect is out. The full game is available now on Windows and Mac, in 12 languages.

The demo has been out since September, and a lot of the last weeks went into fixing what demo players reported. Thank you to everyone who played it and wrote here or on Discord.

In the full game

• All stages. The demo stopped partway, the full game goes to the end.
• Trains. Passenger and freight trains, stations and metro.
• Auto Bend and Arc. Two road tools that are not in the demo. Auto Bend curves a road onto another one for you, Arc draws a circle arc of the size you pick.
• Map editor with Steam Workshop, to make your own maps and play other people's.
• Creative mode, if you just want to build without losing.
• Hard difficulty, bigger maps and four more landmark buildings.
• No limit on bus lines and more save slots.

New since the last demo update

• Smaller, round roundabouts. Rings are real circles and can be much smaller, especially with one-way, normal and gravel roads. Two-way rings no longer lock up when they fill.
• Buses don't bunch. A bus that arrives right behind the previous one waits a little at the stop, so buses spread out along the line.
• Transfers. A stop where two or more lines meet has extra room for people changing lines, so transfers no longer overload it.
• Guidelines. New setting, off by default. "On" draws dashed guide lines, "Snapping" also snaps a T square onto a road and lines up with nearby road ends. Angle and length are now always shown while building.
• An overloaded building names the destination its cars can't reach and marks it red, instead of saying there is no route out.
• Click a car and you also see the route it already drove. The ` key cycles map modes.

Fixes since the last demo update

• Cars stopped one by one on a green with nothing in front when a car ahead was turning into a building.
• Motorway ramps on a bend got wrong lanes, and an extra lane there removed itself with a lag spike.
• Demand-responsive traffic lights mixed up their car limits after loading a save.
• T junctions snap as close to a junction as the rules allow, and never where the build would refuse them.
• Long roads snap less, the end no longer jumps away from the cursor.
• Interchange tool: the second road only turns through allowed angles, and no ramp is built on top of a road next to it.
• Partial upgrade of a short road no longer leaves a piece that can't be upgraded. Short pieces next to a bridge can be upgraded.
• Turn lane tool refuses less often, and says why when a lane never joined the road behind it.
• Centre line kept off a shallow Y where cars cross it; lane lines end at the stop line.
• Zooming in no longer goes under the map.
• If the graphics driver crashes, the game now says so instead of showing a blank map.
• The overload banner no longer covers the map mode list. Esc on stats closes only the stats.
• A lost or deleted city can't come back from its backup. If a save is restored from backup, the game tells you.
• Bus upkeep is shown per minute, so small and large buses no longer look the same.

I made this game alone, and I will keep fixing and adding things after release. If something breaks or feels wrong, tell me here in the discussions or on Discord.
