Transportation simulation model development allows simulating traveller’s decisions, evaluating various transportation management strategies and complex solutions. The aim of the paper is to set the general principles of the transportation simulation model development and validation. The paper contains the overview of the transportation simulation models types with the examples from the conducted projects for the Riga city. The basic steps of the simulation model development procedure: initial data preparation and analysis, transportation model development and simulation, scenarios planning and evaluation, and simulation models outcomes evaluation are considered. Simulation model verification, validation and calibration definitions are given. The basic checks for the transportation macroscopic and microscopic simulation model validation are listed. A summary of the transportation simulation model validation and calibration methods and parameters is given.

As the world economy is becoming globalized, more domestic businesses are branching to overseas. Thereupon the number of expatriate workers who are getting assigned to overseas are increasing, and needs for systematic selection and training system for overseas expatriate workers are in dire needs. Nevertheless researches in this area are not enough and still inadequate level domestically. Therefore we developed the Global Competency Scale (GCS) with the purpose of the local businesses to use it to predict the possibility of successful overseas job performance and to select and train the right overseas expatriate workers. To develop the scale we conducted researches on documentations and interviews with former overseas expatriate workers and expatriate program managers in human resource department(HRD). Based on these results we developed 14 initial factors with 138 items. Using theses items we conducted both on & offline survey to people who work at global and multinational companies in Korea. With the 381 people's survey results, we implemented the cross validity. After cross validating we generated final 6 factors with 24 items. The GCS score we developed in this research shows that the degree of their goal achievement during past overseas experience and level of their satisfaction was significantly high in those criterion variables proving the criterion-related validity. Especially the GCS we developed in this research shows that after controlling the effect of English skills, still appear to have significant effect on criterion variables. Finally based on research results we discussed academical and operational implication and limitations for the further researches.
