Car parking zones are currently just decorations, so why can't them be functional? These zones may be classified into many types: on-road, underground, multi-storey and so on! Also, there may be stopping zones for bus and train at the stations!
2. MULTI-DECKER BRIDGES/OVERPASSES
Why do we need sophisticated tricks to build bridges/overpasses without pillars? Just click a button and then we can build roads above roads! We'll use this with existing functions to create realistic elevated roads!
3. MORE LEVELS FOR TUNNELS
Please add more levels for tunnels as similar as bridges.
4. SUPPORT ROAD DECO FOR SLOPES
Please activate road deco on slopes as doing on flat roads.
5. DIAGONAL SLOPE
We currently have diagonal roads and bridges, but how about a diagonal slope? Will them be possibly implemented?
6. REVERSIBLE ROAD
A two-way road can be switched to one-way road, vice versa and reverses the vehicles' direction, can't it? This function may be custom or depend on day/night mode or rush hour mode to minimize traffic jams!
7. SWING/LIFT BRIDGE
Bridges that can be rotated or lifted to allow boats to go pass! They'll be possible for waterway system!
8. MULTI-DECO MODE FOR ROADS
Why does this mode appear and why is it custom in the game settings? A road that supports multi-deco by default is better than one doesn't, right? Please eliminate it permanently (subjectively speaking, i don't want to click the button by mistake when opening settings as it can destroy all of my effort on building roads whenever!
)9. VEHICLE SURPASSING
Please smooth out vehicles' movement by turning it into diagonal direction as same as one on diagonal roads.
10. EFFECTS FOR ROAD SURFACE
Please add effects on vehicles for road surface besides normal road decos, such as wet state after rain, cracked state in sweltering heat, slippery state after snow, etc.
11. INTERCITY TRANSPORT
We've already had power and water providing services, as well as trash treatment and barial, but transport is currently managed just by routes and road connection from city to city is nonsense. Why don't we allow vehicles to go outside the active city and enter from other cities? Also, please implement management for more types of vehicle like cable cars, trams, waterway transport, helicopters, etc.
12. BUG WITH TRANSPORT MANAGING SCHEME
About the latest transport managing system, when clicking any tile next to a metro station or any road tile at city's edge with set routes, it's very annoying that the window of the system pop up repeatedly and undesirably. Pleaseee fix this inconvenient bug!
13. ROAD NAMING
Add road naming feature as similar as the current labelling tool. This'll be useful for the driving mode!
14. ADJACENT DIAGONAL ROADS
There's a current limitation for constructing diagonal roads with shared median strips: we have to separate 2 parallel diagonal roads by 1 tile at least if we don't want to have them jointed. Why don't we share a tile for separate diagonal roads (4 lanes in total)? This'll be efficient in area saving and possible for building diagonal roads with more than 2 lanes.
15. CUSTOM BUS ROUTES
In the latest transport managing system, we can create, joint, delete and operate routes but cannot assign which roads the buses need to circulate. The system always selects the shortest ways, but not always the roads we want. Why don't we add a feature for assign roads for public buses, espacially at at-grade intersections? This'll help separate lanes/roads for buses, avoid congestion and operate the system more smoothly!
16. FUNCTIONAL ROAD SIGNS, ROAD MARKINGS
Please functionalize various types of road signs and road markings. For example, arrow markings guide vehicles to go as specified, continuos lines prohibit vehicles from crossing while dashed lines allow vehicles to cross, or functional traffic signs such as prohibitory, mandatory, directional, etc help organise and control traffic as desired.
17. ADVANCED DRIVING MODE
Turn current driving mode into realistic vehicle controlling feature, not viewing! Why can't we really drive vehicles, just only view them and the steering wheel is just decorative? Instead, we'll control our vehicles by only going straight, turning right or left and moving back (the speed is assigned automatically by types of roads; dead ends, opposite roads, etc are notified when driving). Furthermore, we'll also be able to drive public vehicles by routes or operate transporation system, as well as more means of transport like train, tram, etc too!
