Most of domestic parking lots are managed one-way system for its prime goal is to minimize traffic conflicts and to obtain convenience of managers, thus it will result in the minimization of internal traffic delays. Some of mega-parking lots developed internal parking route guidance system of each block, recently, but still the effort of improving internal transition methods seems to be vague. This research contains the analysis of decrease in internal traffic delays and improved efficiency of parking lot usage via the alternation of management to allow two-way traffic and introduction of optimized parking routes guidance system(as after PRGS). For the analysis, setting a virtual parking lot to have each alternation or both in order to establish respective scenarios was essential. The analyses of respective scenarios contain the difference in total travel time and total delay time and the change in effect values by the increase in traffic volume. The method of analyses was a micro-simulation algorithm. When introduced the optimized PRGS there was significant decrease in both total travel time and total delay time, and considered most effective when managed with two-way system. The effectiveness of introducing optimized PRGS was proportional to the traffic volume. The results of the research converged to the conclusion of the needs of further researches, both theoretical and practical, of the establishment and management of parking lots. Parking lot itself holds its particular traffic system as the road does, thus by the organized researches, the minimization of unnecessary traffic delays in parking lots can be achieved, ultimately resulting in the energy reduction and the decrease of carbon emission.
