This paper discusses the assessment of road maintenance and network capacity expansion planning, based on network reliability concept. The network reliability could be considered as a user oriented parameter, since it describes the service that the road users might experienced while traveling through a network. The primary arterial road network of Sumatera Island, Indonesia, is chosen to be tested. Several scenarios of network maintenance and capacity expansion were assessed. The considered centroid pairs were the origin-destination pairs with the highest movement of freight and passenger. Results suggest that the network capacity expansion by constructing new roads at certain corridor along central and west coast of Sumatra Island does not necessarily improve the network reliability indices, except for centroid pairs that directly connected to the improved route. On the other hand, the betterment and periodic maintenance program on several road segments might have higher improvement of connectivity reliability compared to the network capacity expansion up to a moderate level of link reliability.
