Ⅳ. R&D Results (1st Year)

Objective - Development of ergonomic evaluation technology for improvement of work environment of locomotive cabs
Indicators-Development of technology analyzing human errors caused by work environment of locomotive cabs
Achievements
1. Investigation into work environment of locomotive cabs
○ Analysis of operation state and characteristics of locomotive cab by type of train (high-speed train, electric locomotive, diesel electric locomotive etc.)
○ Derivation of "driving tasks of upper level" through preliminary investigation into work environment of locomotive cabs through data collection and analysis (including railway vehicles handbooks, operation manuals, inspection guides, other design documents and guidelines etc.)
○ First and second questionnaires for surveying drivers' satisfaction with driving cabs (86 drivers from KORAIL Busan crew management office; 192 drivers from Daegu crew management office; 124 drivers from Guro electric locomotive crew management office; and 81 drivers from Busan KTX crew management office)

2. Selection of trains for research
○ Visit to KORAIL passenger services headquarters/Busan crew management office, requesting cooperation and consultation
○ Selection of “diesel electric locomotive (7400 series)”,“VVVF electric locomotive” and “new electric locomotive(NEL)” as trains for research (reflecting the results of investigation into work environment of locomotive cabs)

3. Analysis of human errors in locomotive cabs
○ Analysis of driver's detailed tasks
- Normal situations: Boarding selected locomotives (total 8 times during daytime and at night in the sections of
“Busan-Dongdaegu” and “Bujeon-Masan”) and interviews with drivers/observations of drivers (video recording)
- Emergency: Visit to a simulator room which simulates the functions of selected locomotives (KORAIL Human Resources Development Institute) and observation of simulated operation in an abnormal scenario
○ Classification of functions of driver's desk equipment and development of a hierarchical model
○ Development of a "hierarchical tasks" model of train operation tasks for analyzing human errors
- Diesel electric locomotive (7400 series): Derivation of 73 detailed tasks in normal situations and 89 detailed tasks in emergency
- New electric locomotive (NEL): Derivation of 117 detailed tasks in normal situations and 181 detailed tasks in emergency
○ Evaluation of driver's load by detailed task using NASA-TLX(Task Load Index)
○ Derivation of “human error classification system” suitable for locomotive cabs
- External Error Modes (EEM), Internal Error Modes (IEM), Performance Shaping Factors (PSFs) etc.
○ Derivation of “detailed driving task requirements” consisting of MMI factors and environmental factors
○ Qualitative human errors analysis for “diesel electric locomotive(7400 series)” and “new electric locomotive (NEL)” in normal and emergency situations
○ Derivation of driver's human error probability by equipment on the driver's desk (Evaluation of MMI human error probability)

4. Development of virtual modelling (CAD) technology for ergonomic evaluation of locomotive cabs
○ Requesting cooperation in provision of drawings and consultation to KORAIL Rolling Stock Technology/Safety Management Department
○ Confirmation of design changes through actual measurement of locomotive cabs
○ Analysis of local and foreign anthropometric data for drivers' virtual modelling and construction of domestic drivers' body CAD model
○ Construction of domestic drivers' body CAD model using the data of physical examination required at the time of acquiring train driver´s license (9,397 cases from Korea Transportation Safety Authority)
○ 2D modelling for driver's cab of "Seoul Subway Line No. 2 VVVF electric locomotive"
- Analysis of man-machine interface (MMI) compared to domestic male/female train drivers' anthropometric measurements based on the requirements of UIC 651 etc.(concerning driver's motion distance, visibility and layout of workspace etc.)
○ 3D modelling and ergonomic evaluation for improved driving cab of “diesel electric locomotive (7400 series)”
- Virtual modelling and ergonomic evaluation for diesel electric locomotive using human modeling CAD(SAMMIE CAD)
○ Suggestion of virtual modelling process for ergonomic evaluation of locomotive cabs

Indicators - Establishment of ergonomic evaluation criteria/require ments management system for evaluation of work environment of locomotive cabs
Achievements
1. Construction of ergonomic evaluation criteria/requirements management process of locomotive cabs
○ Development of ergonomic requirements management process applying SE standard requirements analysis process such as EIA-632, IEEE 1220 and ISO/IEC 15288
○ Collection and analysis of relevant local and foreign data including UK's GM/RT2161 and UIC 651, and America's CFR 49.
○ Creation of initial ergonomic criteria/requirements for locomotive cabs through data analysis (Derivation of total 311 initial requirements)
○ Setting the hierarchical structure through creation of keyword by initial ergonomic criterion/requirement of locomotive cab including the driver's desk, layout and work environment
○ Derivation of ergonomic criteria/requirements through validation and verification of initial ergonomic criteria/requirements of locomotive cabs by hierarchy (including expert verification, derivation of total 236 requirements)
○ Making an ergonomic criteria/requirements report and a reference book for ergonomic evaluation of locomotive cabs

2. Development of a model analyzing traceability for driver's tasks, man-machine interface and solutions for human errors in locomotive cabs
○ Development of the schema of traceability between “drivers' human errors” and “ergonomic criteria/requirements” for railway vehicles
○ Establishment of relations between “drivers' human errors” and “ergonomic criteria/requirements” and verification of the relations for “diesel electric locomotive (7400 series)” and“new electric locomotive (NEL)” (Establishment of total over 1,500 relations)

3. Construction of SE S/W environment for ergonomic criteria/requirements of locomotive cabs
○ Analysis of ergonomic evaluation criteria/requirements, construction of product management DB and development of S/W using SE tool CRADLEⓇ
○ Construction of the environment automatically outputting related scripts and development of S/W
