Abstract

         The aimed to study 1) characteristics of basic personal, economic, and social data; 2) management performance of the Chalerm Mahanakorn Expressway;          3) Factors affecting the efficiency of the information system on the maintenance management of the Chalerm Mahanakorn Expressway, and 4) problems, obstacles, and suggestions concerning the maintenance of the Chalerm Mahanakorn Expressway and the Chalong Rat Expressway. The sample group used in the study was the 23 staff who used the information system for the maintenance of the Chalerm Mahanakorn Expressway and the Chalong Rat Expressway completed the SAP training course and currently still use geographic information system (GIS) for the maintenance. Data were collected by interviews and data were analyzed by using descriptive statistics to find the percentage, mean, and standard deviation. The results of the study showed that

The average working period was 5-10 years (56.6%) with an average income of 25,001 - 35,000 baht (39.1%). The frequency of using information systems in work is used every day (87%) because it is convenient, fast, and efficient (60.9%).

         2) In terms of opinion level on the current management of the Highway Maintenance Division of Chalerm Mahanakorn Expressway and the Chalong Rat Expressway, the results of the study showed that the sum of all aspects was at the highest level with a total mean of 4.49 (S.D. = 0.591). When considering each aspect, it revealed that the respondents had the most average opinion in terms of traffic guidance signs with an average of 4.55, followed by maintenance and the cost of traffic surfaces with an average of 4.50, and sound barriers with an average of 4.43.

         3) In terms of the level of opinions on factors affecting the efficiency of information systems on the maintenance management of the Chalerm Mahanakorn Expressway and the Chalong Rat Expressway, the study revealed that the sum of all aspects was at the highest level with a total mean of 4.56 (S.D. = 0.520). When considering each aspect, it revealed that the mean opinions with the most opinions were in the planning aspect and personnel management in operation with an average of 4.61, followed by reporting with an average of 4.58, coordination with an average of 4.56, budget with an average of 4.56, organization management with an average of 4.53, and administration with an average of 4.50. In terms of problems and suggestions on the information system efficiency for maintenance of the Chalerm Mahanakorn Expressway and the Chalong Rat Expressway.

         4) It revealed that most of them had main problems in terms of maintenance and cost of traffic surfaces because there is the unclear set of repair cycles and it was checked when deterioration occurs; therefore, it causes serious problems such as road accidents. Suggestions to solve the problem should develop an efficient information system in which the information system is considered a storage process, collecting available information into the form of the most useful news by people and information technology in the process to be a conclusion used to support make a person’s decision to be suitable for work or activities. It also includes the maintenance of the Chalerm Mahanakorn Expressway and the Chalong Rat Expressway, which will be able to assess and predict the age of traffic routes before serious problems arise including increasing the frequency of maintenance and improvement of the Chalerm Maha Nakhon Expressway and Chalong Rat Expressway to be a tool for quality work.
