Roads – Definition
Road is a stretch of pavement that trucks ride on (surprise!).
Road(s) has the following properties:
* name – name of the road * next – name of the next road in the series * speed – maximum speed that can be attained on this road * price – price that needs to be paid for 1 meter of single road * maintenance – cost of monthly maintenance of 1m of road * raze – cost of taking 1m of road off * age – how many years it will take before the road starts to deteriorate (deterioration – causes max speed to drop up to 10 km/h after some time – around 5 years) * startyear – year of presentation * endyear – year of discontinuation * shader – name of the shader script of this road
Roads – Directions and Building
Roads are internally saved the same way as track is.
Roads are built using the same principle as trackage -> fist survey mode to plan all the building, then the works commence. The same drag-n-drop method is used.
Roads are by default double direction and require twice the Right-of-way the trains need
Single width ROW roads are possible, but they are always single direction ones (this way complex intersections are possible)
Roads – Grades
Road vehicles use the same curve-to-rise as railroads.
Roads – Intersections
Roads can intersect – these intersections can be even at 90 degree angle. Up to 6 pieces of tarmac can be laid on a single tile. Roundabout will be created if too many stripes of tarmac will be laid.
Roads – Curves
Roads – like tracks – will be a subject of curve smoothing. Just like with tracks curves will restrict speed and cause extra drag.
Roads – Motorways
Motorways are roads that have two lanes – each for different direction. Freeways are built like roads, but are more restricted:
motorways allow only two parts of the road on a single tile, but also cannot turn in a 90 degree angle.
Motorways cannot cross on a single level.
Roads – State and Private Roads
Government will build roads that are for public use. Government roads impose 105 km/h speed limit for buses and 90 km/h speed limit for trucks. (120/100 for govt motorways)
Private roads are roads owned by transport companies – these roads have no speed limits beside the construction ones. Also private roads are usable only for trucks/buses owned by the owner of the road.
Owning a truck imposes certain amount of road tax – which is 5-250% (random?) for the fuel costs when vehicle travels on govt road.
Stations - Loading bays
[Insert Picture]
Loading Bays are structures that allow trucks to load (surprise!). They have a form of bays on the side of the road. If there is a platform on the one side of the bay then the vehicle may reverse. If not (loading platforms are on both sides) then the vehicle will continue.
Leftmost:
Single bay on a single tile.
* green – loading bay * blue – empty vehicle path * red – full vehicle path when reversing
Right:
Long 5 tile loading bay (automatically happens when several bays are built one after another. Can house several trucks, as well as long trucks) – two sided – thus no reversing.
* blue – path of a vehicle (assuming empty bay) * Pink – loading areas.
Note – vehicles will use both sides to load, regardless of the direction they came from.
Loading bay is defined by these properties:
* Model – model(s) used for visuals * startyear – year from which this bay is available * endyear – last year of availability of this bay * price – cost of rising the bay * type – cargo types supported (like ‘hopper’, ‘generic etc’) up to 8 types * cost – cost of monthly upkeep * raze – cost of removing the bay * throughput – the maximum rate of which a cargo can be loaded/unloaded – in tons per second (Realtime). * load – boolean, bay for loading * unload – boolean, bay for unloading
Stations – Workshops
Workshops are special ‘bays’ that are built just like them. They house a full truck – or amount of trucks that a bay of that length would store.
Vehicles – Definitions
Trucks are composed of these fields (as usual there is vehicle and models part)
Vehicle:
* name – text name of the vehicle * year – year of design * price – base price * maintenance – cost of yearly maintenance (fuel excluded). * fuel – type of fuel used * time – time in seconds (real-time) it takes to deliver a ready vehicle from the manufacturer to the workshop it was ordered from * speed – maximum speed of the vehicle * service cost – cost of single service * service time – time of servicing * road – up to 8 types of roads this vehicle can run on * type – type of this vehicle (hopper, platform, van, tanker, carriage, etc – type must be defined before) * vehicle – is this vehicle: rig (single, self contained, may tow a trailer), tractor (carries semi-trailers), trailer or semi-trailer.
Models:
* sndlight – sound when vehicle is at or below 1/4 power * sndmedium – sound when vehicle is between 1/4 and 1/2 power * sndheavy – sound when vehicle is between 1/2 and 3/4 power * sndfull – sound when vehicle is between 3/4 and full power * sndover – sound when vehicle is above full power * sndlowspeed – sound when vehicle is running at low speed * sndhorn - sound of the whistle * power – power (in kW) of the vehicle * capacity – what amount of goods this vehicle can carry * weight – mass associated with this model * next – Next model in class (used for multi-part vehicles – none for single or last vehicle in a consist) * maxTE – maximum tractive effort (0 = do not display, for wagons for instance) * maxBE – maximum braking effort (0 = do not display, for wagons for instance)
Vehicles – Ordering
Vehicles are ordered from a warehouse, and they are serviced and sold there also.
Vehicles – Special Consists
[Insert Picture]
It is possible to attach several semi-trailers to a single tractor and create a road-train
Road trains have these limitations:
* They can only be used on private roads and, if scenario allows, outside city limits * They are much more speed restricted on curves * Maximum length * 56m for state roads and 120m for private roads (if state roads allow RT) * 56m for private roads (if state roads disallow RT)
