- comments:
- The users of this lesson will be the Government land transportation strategic planners and Road design engineers.
The beneficiaries will be the communities living along the road who will have a longer lasting road designed to take the actual traffic load.
- challenges:
- The ERA project did not have the opportunity to investigate the proposed roads to be upgraded before they were selected. Also most of the trial road contracts were selected in the ERA start-up phase. The lack of a detailed projection of future traffic flows induced by the planned road improvement will lead to under-specification of the required road standard. This will lead to the newly constructed road requiring more maintenance than expected for the assumed standard of road (in this case E1) with the road likely to fail or require major rehabilitation sooner.
- success:
- More rigorous analysis of the traffic flow patterns before design would lead to improved road designs. These improvements in pre-design assessment processes would need to be institutionalized within the DRBFC as part of their overall rural road rehabilitation and maintenance activities.
- context:
- In at least two cases (Lihu to Samelete in Ermera and Fatubosa-Liurai-Hatubuilico across Ainaro and Aileu), the new project roads have created shorter and, in the short term, faster alternatives to the existing district roads.
The new roads (rated as E1) were not designed to take the additional traffic now created (or induced) through replacing a lower standard, poorly maintained or much longer B Class inter-district road or a D Class suco to district town.
- description:
- The first results area for the ERA project was to improve rural roads in the target districts. This was to be achieved by using trial construction contracts to rehabilitate rural roads prioritized by the GoTL.
When upgrading rural roads, more detailed traffic analysis is needed to assess if upgrading the road will lead to diversion of additional traffic that would change the design requirements for the road.
- administrative_issues:
- In this case, ERA was not able to significantly influence the selection of rural roads to be rehabilitated. The ERA engineers had adequate resources to design the selected roads to the expected (E1) standard but did not have time or engineering resources to undertake a full analysis of the likely changes to and final traffic loads the rehabilitated roads would probably carry.
