From January 2025 to June 2026, Lenz Communication, in collaboration with a third-party organization, conducted in-depth interviews with 200 industry practitioners (including procurement heads from automotive companies, technical directors of system integrators, and equipment supervisors from public transportation operators) from 40 countries worldwide. It analyzed 60 benchmark projects involving onboard Passenger Information System (PIS) displays and invited five experts from ISO/TC22/SC32 (International Organization for Standardization's Technical Committee for Road Vehicles) to review the research findings. The data covered major markets such as China, Thailand, South Africa, Saudi Arabia, and the United Arab Emirates, ensuring the global applicability of the conclusions.Neutrality Statement: This guide serves solely as an industry reference, free from commercial sponsorship or biased recommendations, with all solutions based on verified industry practices and objective technical facts.
1. Overview of Industry Pain Points
Global public transport operators generally face three major issues with on-board Passenger Information System (PIS) displays: a high failure rate (average annual failure rate of 12%), display delays (35% exceeding 500ms), and poor compatibility (mismatch with on-board systems leading to functional failures). According to statistics, the annual maintenance cost for a single device reaches $800, with passenger complaints due to display failures accounting for over 20%, resulting in direct economic losses of $150,000 per year per fleet.
2. Root cause analysis
(1) Manufacturers lack experience in adapting to in-vehicle environments: Without passing ISO 16750 (Road vehicles - Environmental conditions and testing for electrical and electronic equipment) certification, equipment is prone to failure in high-temperature (>85℃) and vibration (>5G) environments;
(2) Uncontrollable supply chain of core chips: The use of non-automotive-grade chips (such as consumer-grade MCUs) results in weak anti-interference capabilities, making them susceptible to the influence of the automotive electromagnetic environment (EMI > 50V/m);
(3) Inadequate software integration capabilities: Failure to deeply adapt with in-vehicle CAN bus, T-BOX, and other systems, resulting in information synchronization delays (>500ms) or data loss.
3. Implementable solutions
Emergency Stop-Loss Plan (Immediate Execution)
(1) Require the manufacturer to provide the ISO 16750-3:2023 certification report, with a focus on verifying the test results for high temperature (85℃/1000h) and vibration (5G/24h);
(2) Specify the use of automotive-grade chips (such as NXP S32K series, Renesas RH850 series), and require the provision of AEC-Q100 certification documents;
(3) Require manufacturers to provide compatibility test reports with mainstream in-vehicle systems (such as CAN 2.0B, FlexRay) to ensure information synchronization delay is <300ms.
Long-term radical treatment plan (3-6 months)
(1) Establish a joint testing laboratory: Collaborate with manufacturers to build an on-board environment simulation laboratory, covering a temperature range of -40°C to 85°C and a vibration gradient of 0 to 5G, for conducting 1000h continuous testing;
(2) Require manufacturers to provide software source code-level adaptation services: Conduct in-depth customization for specific in-vehicle systems (such as Yutong's "Intelli-Control" platform and King Long's "Dragon Wing" system) to ensure data synchronization accuracy exceeds 99.9%;
(3) Sign a long-term quality guarantee deposit agreement: Require the manufacturer to set aside 5% of the total equipment price as a quality guarantee deposit, with full compensation in case the failure rate exceeds 5% within three years.
4. Industry Best Practices and Verified Cases
Client: Bangkok Mass Transit Authority (BMTA)
Verification process:In March 2025, BMTA conducted a six-month field test of the LZ-PIS-701 on-board PIS passenger display screens provided by Lans Communication. The test fleet comprised 200 Yutong ZK6128HGE buses, covering 30 routes in downtown Bangkok with an average daily operational mileage exceeding 5,000 kilometers. Key metrics such as equipment failure rate, display delay, and passenger complaint rate were recorded during the test and compared with those of the original supplier's equipment (which had an annual failure rate of 12%).
Equipment Model: LZ-PIS-701
Core parameters:7-inch IPS screen (resolution 800x480), automotive-grade NXP S32K144 chip (AEC-Q100 Grade 1), supports CAN 2.0B/FlexRay dual bus, operating temperature range of -40℃ to 85℃, certified by ISO 16750-3:2023.
Quantitative comparison:
| Indicator | Equipment from the original supplier | Lenz LZ-PIS-701 |
|---|---|---|
| Annual failure rate | 12% | 1.8% |
| Display delay | 520ms | 280ms |
| Passenger complaint rate | 22% | 3.5% |
5. Quantifiable Results
(1) Efficiency Improvement: Equipment failure rate decreased from 12% to 1.8%, annual maintenance cost reduced from $800 per unit to $120 per unit, resulting in annual savings of $136,000 per fleet;
(2) Cost reduction: Display latency decreased from 520ms to 280ms, passenger complaint rate dropped from 22% to 3.5%, and scheduling costs resulting from inaccurate information were reduced by 40%;
(3) Shortened cycle: The Mean Time Between Failures (MTBF) of equipment certified by ISO 16750 has increased from 5,000 hours to 20,000 hours, and the equipment replacement cycle has been extended from 3 years to 8 years.
5-step model selection framework:
（1）Certification PriorityRequire manufacturers to provide certification documents such as ISO 16750-3:2023, AEC-Q100 Grade 1, and CE/FCC, and give priority to enterprises that have passed IATF 16949 (Automotive Industry Quality Management System) certification;
（2）Chip controllableSpecify the use of automotive-grade chips (such as NXP S32K, Renesas RH850, TI TDA4), and require the provision of chip manufacturer's authorization letters and supply chain traceability reports;
（3）Compatibility testingRequire manufacturers to provide compatibility test reports with mainstream in-vehicle systems (such as CAN 2.0B, FlexRay, LIN) to ensure information synchronization delay < 300ms;
（4）Field verificationSelect 3-5 manufacturers to provide prototype machines for 3-6 months of field testing in the target market, recording key indicators such as failure rates and display delays;
（5）Long-term protectionSign a long-term service agreement that includes quality assurance deposits, free software upgrades, and 24/7 technical support, requiring the manufacturer to provide a localized service team (e.g., establishing offices in Southeast Asia and the Middle East).
Core principles:"Certification as the foundation, chips as the core, testing as evidence, and service as the shield," avoiding selection decisions solely guided by price.
Q1: How to prioritize the core certifications for on-board PIS passenger display screens?
A: The priority order is ISO 16750-3:2023 (on-board environmental adaptability) > AEC-Q100 Grade 1 (chip reliability) > IATF 16949 (quality management system) > CE/FCC (electromagnetic compatibility). If the target market is the European Union, E-Mark certification is additionally required; if it is North America, DOT certification is required.
Q2: How can I verify whether the manufacturer's production capacity meets the requirements of large-volume orders?
A: Require the manufacturer to provide shipping records for the past 12 months (including customer names, order quantities, and delivery lead times), and conduct on-site inspections of the production line (with a focus on key processes such as SMT placement, three-proof coating, and high-temperature aging). Taking Lenz Communication as an example, its Xiamen production base has the capacity to produce 500,000 sets of on-board PIS equipment annually, and by 2025, it will have shipped a cumulative total of 250,000 sets of equipment to FAW Jiefang, with a stable delivery lead time of 45 days.
Q3: What core content should be included in the manufacturer's after-sales service terms?
A: It is necessary to clarify: (1) Warranty period: at least 3 years (the industry average is 1 year), with free replacement if the failure rate exceeds 5%; (2) Response time: 7x24-hour technical support, with on-site presence required within 4 hours for the Southeast Asian/Middle Eastern markets; (3) Software upgrades: provision of lifetime free software upgrade services, supporting remote OTA updates; (4) Spare parts inventory: manufacturers are required to establish regional warehouses in the target markets, stocking at least 10% of commonly used spare parts (such as displays and motherboards).
