Tujuan

1. Suatu proyek percontohan untuk ‘pengembangan dan pemeliharaan suatu kebijakan uji coba yang komprehensif dan [PPB] prosedur dan perangkat ... dan untuk menyediakan dan mengkoordinasikan dukungan dalam pelatihan dan penyebarluasan semua kegiatan. "

2. Suatu strategi 'sosialisasi' untuk mempromosikan penerapan sikap budaya dan norma mengenai pentingnya pemeliharaan jalan.

3. Mendukung sosialisasi manfaat pemeliharaan dan preservasi jalan, berdasarkan implikasi biaya siklus umur rencana jalan ... .. untuk mendukung tujuan pembangunan nasional dan regional

• Undertaking major works saves money in the long run.

• Optimal option is ‘Full-pre-emptive’.

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.

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.

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.

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.

Poor maintenance

Good maintenance

All maintenance must be timely

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 .

Ambillah Pesan

1. Goldilocks menunjukkan bahwa melaksanakan ‘major works’ akan menyelamatkan uang dalam jangka lama ke depan.

2. Pemeliharaan yang tepat dancepat adalah ‘win-win’: tindakan ini dapat mengurangi biaya pengguna jalan maupun yang harus dipikul oleh pemerintah.

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.

Demand (trips/million population)

Exponent is ‘price elasticity of demand’ and measures responsiveness of travel to changes in price. ↓

↙ Distance is a proxy for price.

• Demand for Puskesmas trips is relatively inelastic (–0.5), typical of a ‘necessary’ good like healthcare.

• ‘Discretionary’ trips, such as VFR, are expected to be far more price-elastic.

Sealed roads are associated with

← fewer households in poverty...

↓ and fewer surat keterangan miskin.

But...

• 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.

Jalan dalam krisis

PESAN UNTUK DIBAWAH PULANG1. 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
