Transport Sector in Cambodia–Focusing on Results

Evaluation Document | 1 September 2009

This sector assistance performance evaluation aims to provide an independent assessment of ADB assistance to Cambodian transport sector during 1992-2008 and identifies key areas for further improving the effectiveness of its operations.

At the beginning of 1992, at the end of decades of conflict and turmoil, Cambodia's transport infrastructure was in poor shape. About two-thirds of the road network was in disrepair, many bridges were destroyed, the railway could not maintain regular service, the two main ports lacked essential equipment, and government lacked the resources and the technical capability to fix the problems on its own.

ADB was instrumental in spearheading Cambodia's recovery process, resuming operations there shortly after the signing of the Paris Peace Accord in 1991. In the transport sector, ADB provided assistance totaling $254 million for 29 projects during 1992-2008.

This sector assistance performance evaluation assesses ADB assistance to the transport sector during this period, finding it successful overall and that ADB contributed significantly to improvements. The study focuses mainly on the road, railway, and aviation subsectors.

Among the key findings, the study says ADB projects in the roads subsector successfully raised the general efficiency of the transport sector. ADB also modestly improved rural access through the upgrading of 50 bridges along two provincial roads and the rehabilitation of about 100 kilometers of provincial roads in the southeast. ADB also improved traffic safety, with design elements and other measures to minimize road traffic accidents on the respective project roads.

Among the lessons highlighted, the study found that Cambodia's participation in initiatives in the Greater Mekong Subregion (GMS) Economic Cooperation program had a beneficial impact. Four of seven loans were designated to GMS projects and two others had strong GMS regional dimensions. In future, however, synergies between the GMS program and the national program need to be emphasized to multiply the benefits.
