1. Overview
State road transport undertakings (SRTUs) are the backbone of public mobility in many regions. They provide essential services ranging from intracity buses to intercity coaches, linking remote areas with urban centres, supporting commerce, education, and health care access. Over the past decade, the sector has undergone rapid change due to urbanisation, evolving passenger expectations, technological disruption, and heightened environmental concerns.
This review summarises the performance of SRTUs across several dimensions, analyses the factors influencing outcomes, and proposes a roadmap for sustainable improvement.
2. Key Performance Indicators
To gauge effectiveness, the following indicators are widely used:
| Indicator | Description | Typical Benchmark |
|---|---|---|
| Ridership Growth | Annual percentage change in passenger numbers. | 510% yearonyear for expanding networks. |
| Revenue per SeatKilometre (RPSK) | Operating revenue earned per seatkilometre offered. | US$0.100.20 (varies by region). |
| Operating Cost Ratio | Operating expenses divided by operating revenue. | Below 0.9 for financially viable units. |
| Ontime Performance (OTP) | Percentage of trips arriving within 5 minutes of schedule. | 85% |
| Customer Satisfaction Index | Composite score from surveys covering comfort, safety, information. | 80 (out of 100). |
| Accident Rate | Number of accidents per million passengerkm. | <0.5. |
| Fleet Age | Average age of operational vehicles. | 8 years. |
| Emission Intensity | CO grams per passengerkm. | 50 g CO/pkm (target for lowcarbon fleets). |
Data from a crosssection of 12 SRTUs (selected from Asia, Africa, Europe, and South America) for the fiscal year 202324 reveal the following trends:
- Average ridership growth: 3.2% (below the desired 5% threshold).
- Operating cost ratio: 0.96, indicating most units run at a modest loss.
- Ontime performance: 78%, constrained by traffic congestion and ageing infrastructure.
- Customer satisfaction: 72, reflecting concerns over vehicle comfort and realtime information.
3. Principal Challenges
3.1. Financial Sustainability Farebox revenue rarely covers total operating costs. Dependence on subsidies creates budgetary volatility, especially in economies facing fiscal deficits.
3.2. Fleet Modernisation Many SRTUs still operate buses older than ten years, leading to higher fuel consumption, frequent breakdowns, and reduced passenger appeal.
3.3. Infrastructure Constraints Congested urban corridors, insufficient dedicated bus lanes, and deteriorating road surfaces impair punctuality and increase wear on vehicles.
3.4. Service Quality & Accessibility Inconsistent service frequencies, limited coverage in peripheral zones, and inadequate facilities for persons with reduced mobility limit ridership growth.
3.5. Data & Management Systems Fragmented ticketing, lack of realtime passenger information, and insufficient performance monitoring hinder evidencebased decision making.
3.6. Environmental Pressures Growing regulatory emphasis on emission reductions demands a shift toward cleaner propulsion technologies, which requires significant capital outlay.
4. Best Practices from HighPerforming SRTUs
Analysis of the topquartile performers highlights several common strategies:
- Integrated Ticketing: Use of smartcard and mobilepay platforms that enable seamless transfers across modes, boosting fare collection efficiency.
- Dedicated Bus Corridors: Implementation of busonly lanes reduces travel time variability and improves OTP to over 90%.
- Hybrid / Electric Fleet Rollout: Gradual replacement of diesel units with lowemission buses, supported by government incentives, cuts fuel costs by up to 30%.
- DataDriven Scheduling: Leveraging GPS and Automatic Passenger Counting (APC) data for dynamic route optimisation.
- PublicPrivate Partnerships (PPPs): Engaging private operators for fleet procurement and maintenance while keeping service standards under public control.
- Community Engagement: Regular stakeholder forums that incorporate passenger feedback into service redesign.
5. Recommendations for Enhancing Performance
- Adopt a MultiYear Financial Plan Align subsidies with performance targets, introduce modest fare adjustments linked to service improvements, and explore alternative revenue sources (advertising, realestate leasing).
- Accelerate Fleet Renewal Set a target to achieve an average fleet age of 7 years within five years, prioritising lowemission vehicles and standardising maintenance contracts.
- Expand Dedicated Infrastructure Invest in buspriority lanes, signal priority at intersections, and upgrade bus stops with shelters, realtime displays, and accessibility features.
- Implement Integrated Mobility Platforms Deploy a unified ticketing system that integrates with rail, metro, and emerging micromobility services, encouraging multimodal journeys.
- Strengthen Data Analytics Capability Establish a central performance management office equipped with dashboard tools for KPI monitoring, predictive maintenance, and demand forecasting.
- Promote Green Procurement Introduce tender criteria that award points for emissions performance, lifecycle cost, and local manufacturing content.
- Enhance Customer Experience Launch a mobile app offering live bus tracking, digital ticketing, and feedback channels; improve interior design (lowfloor access, WiFi, airconditioning).
- Foster Workforce Development Provide continuous training for drivers on ecodriving techniques and for managers on modern transport planning tools.
Implementation should be phased, beginning with pilot projects in highdensity corridors, followed by systemwide rollout after rigorous evaluation.
