Two kinds of efficiency TTC RAC RUC Cost Level of service Technical efficiency Allocative efficiency Better ride quality Where we are now Where we want to be Maximise technical efficiency. Maximise allocative efficiency by... trading off RUCs and RACs to minimise total transport cost. This is the optimal level of service. Maximise technical efficiency.

10 It pays to be on time Conducting repairs promptly is often win-win. Even when it’s win-lose, it’s beneficial overall. So road users can pay for it and still be ahead. It reduces costs for road users and the road agency alike. Conducting repairs promptly is often win-win. Even when it’s win-lose, it’s beneficial overall.

How routine maintenance affects defects Area affected by defects (%) Age of pavement Poor maintenance Good maintenance Once they start, defects grow explosively. Good routine maintenance can delay their onset. Once they start, defects grow explosively. Good routine maintenance can delay their onset.

How routine maintenance affects roughness Roughness Age of pavement As defects grow, roughness rises, which increases vehicle operating cost travel time discomfort. Good routine maintenance keeps pavements smoother longer. As defects grow, roughness rises, which increases vehicle operating cost travel time discomfort.

All maintenance must be timely Life-cycle cost Age of pavement Routine Periodic Routine Periodic Routine Periodic Routine Periodic Policy space Both routine and periodic maintenance must be on time. If either is late, RUC and RAC are higher than they need be. Prompt routine maintenance extends road life and requires less frequent periodic maintenance.

17 The demand for trips Source: Indonesian Family Life Survey (IFLS) Exponent is ‘price elasticity of demand’ and measures responsiveness of travel to changes in price. ↓ ↙ Distance is a proxy for price. Demand is relatively inelastic (– 0.46), typical of a ‘necessary’ good like healthcare. ‘Discretionary’ trips, such as VFR, are expected to be far more price-elastic.

Poverty is not all attributable to road condition; other facilities must change too. Causality is not one-way: the poor may lack good roads for other reasons. Source: Potensi Desa (Podes)

24 Jalan dalam krisis PESAN UNTUK DIBAWAH PULANG 1.Suatu pemeliharaan jalan lebih ilaksanakan secara menyeluruh dan terpadu dari pada dilaksanakan secara sepotong-sepotong. 2.Penetapan kebutuhan perjalanan adalah hal yang penting yang dapat mempermudah perhitungan manfaat sosial, yang akan mengarah pada perhitungan kebutuhan sumber daya. 3.Ada hubungan antara kondisi jalan dengan kesejahteraan masyarakat
