In this study commuter marriage was defined as a family in which working husband and wife, who have professional job having family orientation and job orientation, come and go lived separately for more than days a week for working in different region. This study examined the determinants of living separately the merits and demerits of commuter marriage, relation with family, family finance and household work for twelve case wives fitted for above definition, and the findings are as the following. The main cause of commuter marriage was wife's work place. The merits of commuter marriage were that wives can devote to their own increased time and that they had fresh feeling to their husbands. The demerit were mental burden to mother-in-laws and their mothers who take charge of home management and the high cost of living for double housekeeping. In the area of relation with family, they and their husbands call above one time per day for communication although they live separately for three or four days, do not insist on norms of living together, and overcome difficulties of commuter marriage well. In the area of family six couples used allowances method. They have high living cost like traffic expenses, telephone charges, and housing expenses because of double living. In the area of household work, they mainly manage family life with the help of household helpers like mother-in-laws or their own mothers.

This study finds a way to increase the usability of a subway commuter pass. Usability of the commuter pass on a probabilistic statistical model is calculated when the pass is allowed to used in a different mode(bus). A sunk cost of commuter pass is used to reduce the vehicle travels from public transit. 324 people aged 25 to 35 were surveyed and utilized to build a Nested Logit Model on STRADA 3.5 platform. Main results are as follows. First, commuter passes were issued in various forms. Second, the model turns out to be statistically significant in four explanatory variables (discount rate, inter-usablity between modes, forms of payment and periods). Lastly, the more valid on different modes, the more increased of the rail commuter pass.

A ride quality measurement was carried out for commuter and express train used in airport railway. Lateral and vertical directional average ride quality level is higher than that of longitudinal direction. Because express train is faster than commuter train, the average ride quality level of express train is higher compared to that of commuter train. The average ride quality level of commuter train is between 'good comfortable($100{\sim}105dB$)' and 'very good comfortable(below 100dB)'. The average ride quality level of express train is between 'not comfortable($105{\sim}110dB$)' and 'good comfortable($100{\sim}105dB$)'. In spite of the scheduled speed is higher(more than 70km/h for commuter train, more than 80km/h for express train) than other lines, the ride quality of airport railway train is good. The reason is that there is little gradient in rail and the radius of curvature is larger compared to that of other lines.

Transportation planners are increasingly adopting policies aimed at changing travel choices made by general commuter. Theories on the relationship between high-speed technology and transport address changes in travel behavior of regional commuter due to alterations in the Kyung-Bu railroad transportation corridor. The purpose of this paper is to examine the relationships between travel behavior and high-speed technology. The KORAIL data allows us to explore the differences between travel characteristics that are usually hard to discern by guesswork. The effects of travel time were found to be significant in the full decisions that control for commuting KTX. Although many argue that transportation behavior cannot be changed, this paper demonstrates that about 4 years of behavioral data on KTX travel show otherwise. In this paper we explore several possibilities to fill in some of the gaps in our knowledge on the expansion of commuter belt.

This study analyzed the objective indicators of household economic structures, such as income, expenditure, and debts, as well as a subjective evaluation of economic standards, and compared the households of commuting couples (so called Weekend couples) with those of non-commuting couples. Findings of this study are as follows. First, both husbands and wives in commuter marriages had a higher level of education, were younger, had poorer health, and had shorter working hours than the couples in non-commuter marriages. Second, commuting couples had a significantly higher income than non-commuting couples. In addition, commuting couples had a greater amount of savings, had a higher cost of living, and lower debts than non-commuting couples. Third, commuting couples evaluated their status of household economy more negatively than non-commuting couples. Despite the fact that the commuting couples were more affluent in terms of the objective indicators, including income, savings, and assets, their level of health and psychological well-being were compromised. Lastly, factors determining commuter marriages were the number of years the husband has spent in his job, and the husband's level of education. The shorter the tenure of the husband's job, and the higher the level of husband's education, the more likely the couple was in a commuter marriage.

This study analyzes the changes in commuter's mode choice between 2002 and 2006 according to the implement of the integrated public transit system in Seoul metropolitan city. Especially this study focuses on differential changes in a transit modal choice among socioeconomic status, trip purpose and spatial characteristics of origin and destination. The probability of public transit use against automobile is modeled as a function of socioeconomic variables, spatial characteristics of origin and destination and the utility of the commuter's mode. The results from conditional logit model analyses suggest that people with lower income show the larger changes in the ratio of public transit choice between 2002-06. Also both higher density, more accessible to public transit and more diverse land uses in residence zone and in work place generally increase the ratio of public transit choice between 2002-06. Car and subway have the most strong alternative relation in commuter's mode choice. The findings give an important implication that the integrated public transit system has differential impacts on commuter's mode choice in Seoul.

As the traffic congestion and parking problems in urban areas are increased the tall and narrow commuter vehicles have interested as a means to increase the utilization of existing freewa- ys and parking facilities. However, in hard cornering those vehicles could reduce stability against overturning compared to conventional vehicles. This tendency can be mitigated by tilting the body toward the inside of the turn. In this paper those tilting vehicles are considered in which at speed at least, the tilt angle is controlled by steering the front wheels. In other word, if the driver turns the steering wheel the tilt controller automatically steers the road wheel to tilt the body inside of the turn. Also, the dynamic tilting vehicle model with tire slip angles is constructed by adding the roll degree of freedom. Finally, through computer simulation the behaviors of the tilting vehicles are investigated.

The purpose of this study was to investigate the relationship between mothers' marital adjustment and children's social adjustment in commuter couples. The subjects of this study were 96 mother-child dyads. The children were first to sixth grade in the elementary schools. For data analyses, one-way ANOVAs, Scheffe Test for pairwise comparison, Pearson's Correlation were used. Results indicated that there were significant differences in mothers' marital adjustment in terms of the duration of commuting, the number of children, the frequency of fathers' visit and frequency of making a call. And, there was significant difference in children's adaptation in terms of the frequency of fathers' visit. Also, there were significant positive correlations between mothers' marital adjustment subscales and children's social adjustment subscales in commuter couples.

Nowadays, the bus system of a metropolitan area is improving very fast. According to the bus, commuter railways increase their competitive power. For this, trains get the mobility increasing, effective transferring system and unified information service. For the mobility increasing, commuting railway must be faster by flexible train diagram and facilities improvement. And finally, optimal commuter train, 'Liner' is needful. And for effective transferring system, it is necessary that railway station and transferring center of a city be merged. And it is needful that direct management bus by railway company and unification fare system on metropolitan region. Next, for information service system improving, the commuting railway station must be regional transportation hub at first. And it is needful that unified line map of trunk line transportation systems and regionally collective transportation system information book. Therefore, metropolitan commuting railways compete with trunk line bus and cooperate with feeder line bus, and can make optimal metropolitan public transportation systems.

Now, the population and economical power is deeply concentrated to Seoul-metropolitan region, therefoere the provinces is so lagging behind and the country cannot get balance development. And, like metropolitan region, the more outer the living area of local wide-area city is spreading, the more serious wide-region transportation problems are. But the railroads near wide-area city fun seldom commuter train, so they cannot absorb the transportation demand of wide-area city metropolitan region. To solve above transportation problem, local wide- area cities try to make a subway or a light rail transit. But it is so difficult because the limit of public finance and original small capacity of light rail. In the paper, I propose 'Local city wide-area electric railways' system of the consortium of 'Local wide-city and province transportation union', Korean National Railroad (KNR) and local capital. A 'Local wide-city and province transportation union' operates commuter railways directly using the facilities of KNR, and local capital invests to the stations of above railways system. Therefore the commuter railway system around local wide-city region will be constructed quickly and the stations will be the strong point of local development and investment.
