This makes me hungry.

What I did

Started implementing a new road construction system

• allows manipulation of indivdual lanes or groups of lanes
• easy to use, but still allows very advanced road designs

What I will probably do next

Add missing connection options

Implement automatic intersection generation

Connect the new road system to...

• the traffic simulation, and add new multilane-traffic behaviours
• the procedural building generation, so that it supports curved roads
