Trade Routes allow a city to trade with another city, generating DustSmall.pngDust and ScienceSmall.pngScience income.

Creating Trade Routes[edit | edit source]

The first step in creating trade routes is to research Imperial Highways or Cargo Docks. These technologies allow the Right of Way or Cargo Docks improvements to be built, which allow cities to be connected by land or by sea. Two cities are connected by land if they are in adjacent regions and have both built the Right of Way improvement. Two cities are connected by sea if they border the same ocean and have both built the Cargo Docks improvement in that ocean. Additionally, if two cities are connected by land or by sea to a third city, then they are also connected themselves. This means that two cities may be connected via a complicated series of alternating land and sea routes.

Note that only friendly cities (that is, cities belonging to empires that are either at peace or in an alliance) may be connected. Alternatively, if a city is governed by a Roving Clans hero with the Black Marketeer skill, then that city may be connected to any other city.

Once two cities are connected, then trade routes may be created between them. By default, each city may create one trade route, and each capital may create two trade routes. (This number can be increased by various city improvements.) If a city may create multiple possible trade routes, then the ones that generate the most DustSmall.pngDust and ScienceSmall.pngScience will automatically be selected.

The city creating the trade route is called the origin, and the city which it connects to is called the destination. Empires only receive income from trade routes originating from its own cities, but not from trade routes originating in other empires and connecting to its cities. Additionally, most trade route bonuses apply only to the origin city or empire.

You can check the status of all trade routes originating in your empire in the Empire Management Screen (default keybind F1).

Improving Trade Routes[edit | edit source]

The base DustSmall.pngDust and ScienceSmall.pngScience generated by a trade route is determined by the distance between the two cities and the population of the destination city. However, trade route bonuses generally only apply to the origin city; for example, having a Caravanserai in a city only improves the trade routes originating in that city, but not the trade routes having that city as a destination. See the Calculation section for more details.

Secondary Trade Routes[edit | edit source]

When a trade route passes through multiple cities between the origin and destination, all of the cities in between also receive bonus income based on the main trade route. This is called a Secondary Trade Route. While a city may be limited on how many on primary trade routes it can create, it can have an unlimited amount of secondary trade routes passing through it.

Calculation[edit | edit source]

The DustSmall.pngDust and ScienceSmall.pngScience yields for a primary trade route are computed using the following formulae:

DustSmall.png yield = (1 + 0.6 × (DestinationPopulation + 0.3 × TradeRouteDistance)) × (1 + TradeRouteBonus) × (1 + TradeRouteDustBonus)

ScienceSmall.png yield = (1 + 0.6 × (DestinationPopulation + 0.3 × TradeRouteDistance)) × (1 + TradeRouteBonus) × (1 + TradeRouteScienceBonus)

Notes[edit | edit source]

  1. DestinationPopulation does not include population from pacified villages.
  2. The grassilk booster is applied after the above formula: its bonus is not added to the TradeRouteDustBonus attribute, but rather it simply doubles the dust income from primary trade routes after everything else has been computed. This means that it is extremely effective at increasing dust income from trade routes.
  3. For all intents and purposes, trade route income is considered a part of city income. This means that it is modified by city-wide or empire-wide percentage bonuses such as the Empire Mint.
  4. The +1DustSmall.png/+1DustSmall.png/+2DustSmall.pngDust bonus from the Fast Trader hero skill and the +1ScienceSmall.png/+1ScienceSmall.png/+2ScienceSmall.pngScience bonus from the Mechanical Exhibitionist hero skill are currently not implemented. (The percentage bonuses from those skills still work correctly, however.)
  5. Secondary trade route income is determined only from the base income of the primary trade routes passing through a city. Additionally, none of the trade route modifiers affect secondary trade routes.
