This study reviews the current situation of taxis roadworthiness inspection resulting from the Periodic Technical Inspection (PTI) conducted by PUSPAKOM. This is in pursuant to a directive from Ministry of Transport on taxi issues, which proposed the possibility of reducing the frequencies for periodical inspection at Periodical Technical Inspection (PTI) for taxis. The objectives of this study are to analyse the current situation of PTI focusing only on taxis, to explore the potential to reduce the inspection term for taxis and finally to recommend the best solution.
The data was obtained from PUSPAKOM and the dataset only involved taxis which had been sent to PUSPAKOM for roadworthiness inspection which includes initial inspection and periodic inspection. The majority of the taxis are EA type (Perkhidmatan Awam Teksi) with about 60% of the overall of the taxi population.
Using logistic regression analysis, the probability of failure of PTI by the taxi was developed. The results indicate that with the existing periodic technical inspection for roadworthiness, the probability of an EA type taxi to have failed the periodic inspection (PTI) reaches 50% after Year-2 before Year-3. Moreover, for a well-maintained EA type taxi which had never failed before, the probability of it to fail in the coming inspection would reach 50% in Year-5.
Based on the analysis result and from the statistical probability model developed, the following recommendations are proposed:
- To maintain the existing practice for the first two years with annual periodic technical inspection;
- Subsequent PTI depends on how well the roadworthiness condition of the vehicle with a possibility of extending the annual PTI up to five years;
- PTI for after Year-5 will be twice a year (every six months);
- If a vehicle has failed in any of the first two years or subsequent annual inspections, then the subsequent PTI after Year-2 will be every six months.
