The Roads Filter is an analysis tool that ranks road projects depending on their level of economic, environmental, socio-political, and cultural risk. The overall risk of each project is assessed through an index built from 17 variables grouped into four categories and weighted according to their relative importance. In order to combine quantitative and qualitative variables in index form, variables are represented as a numerical value between 1-5, with 1 being the best (least risky) in terms of economic feasibility and low environmental, social and cultural impacts.

In 2011, we applied the Roads Filter to 36 proposed roads in the region. The overall ranking of these roads is seen in the table below. Users can sort the roads by country, road or rank. Additionally, users can adjust the weights by creating a custom filter and modifying each rank according to preference.
What is risk
Risk is a computed value from 1-5, which takes into consideration road-specific variables for sub-categories within each main category (economic, environmental, social, cultural) and assigned weights. The possible values risk can be ranges from 1 being the least amount of risk (better) and 5 being the most amount of risk (worse).What is rank
Rank is based on risk compared to all other roads in the Roads Filter.
