This study aims to identify the actual condition of local food stores that serve as a regional activation space within the highway rest area. It analyzes and examines user awareness, and presents desirable directions for the establishment of new local food stores and improvement of existing facilities. The research method was conducted as follows: the status of 226 rest areas were examined which were installed on national highways, location conditions and convenience facilities. Second, a physical survey was conducted on 116 local food stores(floor area, location) and a user awareness survey on 63 local food stores. The results of the analysis and review have been concluded as follows. First, it is necessary to consider the establishment of a local food store in order to promote the local community by using various cultural and environmental conditions in the highway rest area, and to secure a public space to promote exchanges with local residents and revitalize the local economy. Second, considering the continuous increase of highway users, location, and traffic conditions, diversification of convenience functions including local food stores should be considered even if it is a medium and small highway rest area. Third, the floor area of local food stores is generally planned within a range of $75m^2$ to $125m^2$, and its location should be integrated with the rest area as much as possible. Inevitably, when you need to construct separately at the exit or entrance, you need to consider a unique design that ensures accessibility and visibility.

Highway Rest Areas are envisioned to provide an accessible space for rest and parking for travelers, especially those driving a long distance. In addition, modern highway Rest Areas provide many amenities to highway users, including wifi service, picnic tables, litter barrels, running water, public telephones, and sometimes even free coffee. Various studies were conducted in the domain of Rest Area facility design and their operating costs in different states; however, limited studies were conducted on the maintenance costs of these facilities. Therefore, this study's main objective is to compute the annual maintenance cost of Rest Areas in the state of Nevada. This study also analyzes the main cost categories of the maintenance works. The raw cost data of Nevada Rest Area maintenance from 1990 to 2012 were collected from the Nevada Department of Transportation (NDOT). Results show that the maintenance cost fluctuated over the study period; the maintenance cost decreased from 1991 to 2004 and then increased until 2012. The primary cost categories of maintenance work are labor, equipment, and material costs. Among these, labor cost was the largest category with 56 percent of the total maintenance cost, followed by equipment cost and material cost. The findings of this study may help NDOT and other transportation agencies plan their budget for future Rest Area maintenance activities.

PURPOSES: Design of approach roads of rest areas in highway has many drawbacks such as geometric design elements. There has been traffic accidents occured in these approach roads of rest areas. Thus, design criteria is required in order to protect accidents from being occurred. In case of Korea, geometric structure design criteria of entry facilities, such as toll-gate, interchange, junction etc was established. However there are no presence in a detailed standards for geometric structure of the rest area which affiliated road facilities. METHODS: In this study, analytic on accidents was carried out in regards to the entry of geometric structure of resting areas by utilizing a sight survey and an investigation research of traffic accidents. The survey was targeting 135 general service areas. Collisions with physical channelization and safety facilities occurred due to speeding, rapid entry, and etc at the entrance nose section. At the entrance connector roads, accidents caused by speeding, negligence, over-operation of handle of drivers were main reason of accidents. Discriminant analysis were conducted about geometric elements to distinguish influencing factors for traffic accidents. the lengths and access angles of the entrance connector roads were regarded as to have the high relation with traffic accidents. RESULTS: After classifying the design section of resting areas' entry as well as derive design elements on each section, a speed measurement by targeting entry of rest areas and car behavior surveys were performed, then each element's minimum standard was derived through the analyses. According to the speeds at the starting/end point of entrance connector road, the range of the junction setting angle of the entrance connector road is defined as $12^{\circ}{\sim}17^{\circ}$ and the connector length model was suggested. CONCLUSIONS: Suggest improvement plans for existing rest areas that can be applied realistically. This should be corresponded to the standards of entry and exit of developed rest areas.

Vegetation surveys were performed at 45 plots along 10 highways cut slopes in South Korea. Total floral inventory, species richness and exotic plant percentage were obtained within each plot. Life history and life form of each species appeared were analyzed. Community types were classified using hierarchical cluster analysis and detrended correspondence analysis and non-metric multidimensional scaling were conducted from vegetation matrix. 292 species of vascular plants were discovered and the number of natives and exotics were 226 and 66, respectively. There were no significant differences of species richness and exotic plant percentage between cut slopes and rest areas. Hierarchical cluster analysis indicated five clear vegetation associations in cut slopes and rest areas. Detrended correspondence analysis indicated that species composition of total and native plants were similar along the highway cut slopes whereas exotic plants were distributed differentially along the highway cut slopes. in non-metric multidimensional scaling, the studied sites were more separated from each other on the basis of their species composition than the results of detrended correspondence analysis with respect to total, native and exotic plants. The both ordination represented that exotic plants have not been made uniform yet on cut slopes and rest areas by highway corridor in spite of diverse chronosequences after highway construction termination (1 to 22 years). This study showed that the distribution of species composition in exotic plants was different and localized on cut slopes and rest areas of highway in this representative peninsula area of North East Asia and the invasion of exotic plants can retard the process of plant species homogenization.

PURPOSES : This study intends to estimate the tangible benefits derived from the integration of operations of an Express Intercity Bus Terminal and a Highway Service Area. METHODS: For the study, a highway service area was chosen to function as a bus terminal, integrating its services with that of a nearby bus terminal plagued by operating losses. The exercise also helped improve mobility owing to the introduction of local buses between the terminals and utilization of the existing infrastructure such as rest areas. Thus, a terminal that was not being utilized for its intended functionality was integrated with an existing facility to improve the utilization of both and subsequently aid local development. The impact of the exercise was then measured by evaluating the variation in utilization efficiency, operating costs, travel time between two regions (Seoul-Jeomchon and Seoul-Geumsan), and the social costs before and after the integration of the two facilities. RESULTS :The impact of the integration was an increase in utilization efficiency, a decrease in operating cost, a decrease in travel time, and a decrease in social cost in both the regions. The benefits of improved utilization and cost saving can be passed on to the citizens in the form of discounts. A local power generation facility will eventually replace the bus terminal, which can revitalize the local economy. CONCLUSIONS :The integration of the highway service area with the bus terminal is expected to have a win-win effect on the passengers as well as the operators. The study also proposes a sustainable strategic plan for existing terminals and rest areas to implement a method to compete with KTX transportation.

휴게소는 장거리 운전자나 졸음 운전자가 충분히 쉴 수 있는 공간을 조성하여 사고를 미연에 방지하는 중요한 역할을 한다. 따라서 휴게소의 적절한 위치 선정은 필수적이며, 이를 위해 정확한 수요 예측과 이용자 통행 행태를 분석하는 것은 매우 중요하다. 따라서 본 연구는 고속도로에서 RSE를 통해 수집되는 DSRC자료를 이용하여 안성휴게소(상행)를 이용하는 휴게소 이용자의 통행 행태를 분석하였으며, 통행행태지표를 토대로 휴게소 이용 확률 모형을 개발하고 검증하였다. 분석결과, 안성 휴게소(상행) 이용 행태는 통행시간이 평일 90분 이상, 주말 70분 이상일때 가장 이용 빈도가 높았으며, 휴게소부터 통행종료까지 남은 거리가 30km 이하일 때, 휴게소 이용률은 급격히 감소하는 것으로 분석되었다. 본 연구의 휴게소 이용 확률 모형을 통해 추정된 휴게소 이용률은 실이용률과 1~2%오차가 발생했다. 본 연구 결과는 정형화된 자료를 이용하여 휴게소 이용 행태를 분석한데 의의가 있으며, 본 연구의 휴게소 이용차량 분별방법론과 개별휴게소이용확률 모형 개발방법은 향후 휴게소 입지선정과 이용자의 서비스 수준 향상을 위한 차별화 전략에 적극 활용될 수 있을 것으로 판단된다.

In the United States, the Safety Rest Areas (SRAs) were introduced as highway roadside infrastructures in the early 1900s. The State Departments of Transportation (DOTs) operate/maintain their SRAs using different methods. The Washington DOT used the in-house workforce method for over 20 years, whereas some states moved to Performance-Based Contracting (PBC) from the in-house workforce to save cost primarily. Several existing studies claimed that using the PBC approach saved costs on several highway assets. Thus, the principal objective of this study is to compute and compare the unit operating/maintenance cost of SRAs using the in-house workforce method (in Washington state) with the PBC approach (in other states). The findings of this study show that the average annual cost using the PBC approach was much more than the average annual cost using the in-house workforce approach. The findings also show that in Washington state, the 'Labor Cost' category was a key expenditure, which is statistically higher than other categories. The 'Labor Cost' was followed by the 'Other Services', and then 'Materials and Supplies' and 'Equipment.' The study's findings indicated that outsourcing does not always save costs for agencies. The study findings may help transportation construction/maintenance professionals select a cost-effective approach for their future planning.
