| Summary | Recently many developed countries have deployed wireless communi-cation technologies to overcome the drawbacks of high costs of wired line con-struction and transmission for traffic information services. It is anticipated that several wireless communication technologies with high mobility and data rate (WiMAX, WiBro) will be soon available for urban traffic control and manage-ment. The main purpose of this paper aims at proposing an evaluation process to identify feasible wireless communication network alternatives for urban traf-fic field devices. Taipei has been chosen as the empirical case study by using a hierarchy framework including 4 objectives (function, quality, cost and system) and 16 criteria. It is found that weight of cost is the highest and weight of system is the lowest for each alternative. So far the alternative A8 (2.5G/3G+WLAN/WiMAX) is regarded as the most comprehensive wireless communication network for the long-term development. Considering standard conditions with quality and quantity criteria the most appropriate evaluation method is MEQQD. An evaluation process is also provided to depict the road-map of deploying wireless communication networks for urban traffic manage-ment devices. This evaluation structure and decision process will be still useful to seek the most appropriate wireless communication network focusing on the communication demands of different site equipment even though new wireless communication technologies will appear in the future. |
