Timed Traffic Light

[Opus Aeterna]

Very important in this game to control better the traffic jam! Why is there any mod about Timed Traffic Light so we can add an individual timer on each traffic lights in the intersections?

Because there are too many intersections, and controlling all of them individually probably causes a drain on resources.
I do agree that there are traffic jams caused by bad timing of traffic lights, but I suspect that the main problem is that we tend (I tend, anyway) to be simplistic with the city layout, and just use the standard blocks too often. Some through roads would probably benefit from being elevated, or underground, with "clever" on/off ramps where necessary. At the very least, you should use a layered approach to roads - big, wide, arterial roads for the fast moving traffic, with complex interchange, and widths to suit the traffic you are trying to move; smaller, but still significant, "Feeder" roads, from the Arterials to the neighbourhood areas, and less conspicuous roads in the local neighbourhoods. - all these layers accompanied with "smart but appropriate" junctions / interchanges,
And don't forget that Arterials can be both overground, and underground, so there is no real reason for clashes in the treetops. Underground Arterials don't create as much noise as Overheads, either, I suspect, and they don't interrupt the view of the scenery.
And you can easily layer underground routes, with main arterials being as far as 50 feet underground, and lesser roads spatially higher up as needed.
