Hi Petr,
In response to your questions:
1) In TSIRC’s website, you’ll find information on Saibai’s Road Register, including relevant definitions.
2) To determine the road sections that are economically important for the island, I suggest that you take stock of the available assets and services in the community. You may check Saibai Community Booklet for more information about this.
3) The preferred method of transportation may be highly subjective. Given that the town is small, everything seems walkable according to our EWB Challenge scoping team.
4) According to this resource: Torres Strait Sustainable Land Use Plan, Part 2 Saibai, there’s 79 privately owned vehicles as of 2006. Please check that resource for more context regarding car ownership and road conditions.
I hope this helps.
Regards,
Jean
