  • PERFORMANCE EVALUATION OF CONSECUTIVE SIGNALIZED INTERSECTIONS UNDER HETEROGENEOUS TRAFFIC CONDITIONS IN CAIRO, EGYPT

    This article highlights the operational performance evaluation of consecutive signalized intersections under heterogeneous traffic conditions. It investigates the impacts of such traffic conditions, as a dominant operation in developing cities, on a set of four signalized intersections located in an urban arterial corridor in Cairo, Egypt. Therefore, the influences of complexities due to the heterogeneity in traffic operation including the diverse static and dynamic properties of vehicles, aggressive drivers' behavior and the lack of lane discipline were investigated. To accomplish this research objective, PTV-VISSIM, as a microsimulation environment was employed to analyze and estimate the Level of Service (LOS) of the studied intersections. To represent the studied intersections as indisputable as the reality, special attention was given to calibrating and validating different simulation parameters. The results emphasized the significant impact of the heterogeneous traffic conditions on the studied intersections, especially under heavy traffic conditions during peak hours. The intersections throughputs, delays, discharge rates and the total travel time was dramatically impacted. This study recommends the necessity of deployments new innovative schemes, in which the operational performance of the existing conventional intersections could be enhanced. Unconventional intersection designs as a viable interstation treatment could be proposed to alleviate congestions.

  • A STUDY ON BRIDGE MANAGEMENT STRATEGY INCLUDING ABOLITION BY COMPARING REDUCTION OF MAINTENANCE COST AND DECLINING OF AREA UTILITY

     View Summary

    In Japan the road bridge is facing rapid deterioration and its damage is serious. As a results, even if preventive maintenance are carried out, its repair and renewal expenses are huge and it's difficult to maintain all road bridges with preventive maintenance type. Therefore, there is a need to adopt not only preventive maintenance but also abolition of road bridge. But in order to gain understanding of the residents, a method to objectively show the effect and impact of abolition of the road bridge is required. In this study, we presented a method to compare the reduction effect of future maintenance and renewal cost and the loss due to the decline of area utility as calculation of cost effectiveness by abolition of bridge. As a result of calculation, there were no bridges with the effect of abolition. However, compared to other bridges, there were bridges with low maintenance effect and there is a possibility that these bridges have room for abolishment. In addition, we presented how to maintain including abolition of bridge as follows. When you abolish the bridge, it is one way to show the proposed infrastructure to compensate for losses. On the other hand, the effect of maintaining the bridge increases by decreasing maintenance costs.

  • A STUDY ON SUSTAINABLE BUS RAPID TRANSIT IN DEVELOPING CITIES—A CASE STUDY OF BANGKOK BRT—

     View Summary

    Although seven years have passed since the Bangkok Bus Rapid Transit System started the operation as one of the mass transit system in Bangkok, it has some problem that the number of users is less than expected and it had lost about 1.0 billion THB over the past seven years. Then, the Bangkok Metropolitan Administration (BMA) once decided to shut down the BRT at the end of April 2017. But after that, BMA stopped the abolition due to lack of public transportation along the BRT corridor and the collection of investment funds. Therefore, this study focuses on the sustainability of Bangkok BRT from technical and financial points of view. First, the analysis from the technical points of view revealed that harmonizing BRT operation with traffic signal control may reduce some factors worsening punctuality and increase the number of BRT operation with the same number of vehicles, without increasing the cost. And the analysis from financial points of view revealed the possibility of existence of BRT headway and operating section that may activate the potential of the BRT system.

  • STUDY ON THE APPLICABILITY OF ALTERNATIVE INTERSECTIONS IN JAPAN

     View Summary

    There are conflict points between through vehicles and right turn vehicles at grade intersections. Some countries, especially United States, propose and introduce Alternative Intersections (AI) which may offer additional benefits compared to conventional intersections. The objective in this study is to obtain knowledge for the applicability of AI in Japan. First, We selected intersections where AI is considered to be applicable from existing intersections in Japan and virtually reproduced AI using micro traffic simulation with observation data as basic input data and evaluated its performance. In addition, we evaluated whether Japanese drivers can drive through AI without hesitation and anxiety using driving simulator. As a result, we showed positive and negative reactions of Japanese drivers to AI which could be mitigated by careful design treatments.

  • A STUDY ON ANALYSIS OF PASSENGERS' DECREASE FACTORS AT THE RAILWAY STATION IN THE SUBURBS OF THE METROPOLIS

     View Summary

    In the Tokyo metropolitan area, cities were formed along with railway maintenance. The number of railway transportation personnel in the Tokyo metropolitan area in recent years is increasing. However, if you check the trends in number of passengers individually, you can check many reduced railway stations. Focusing on the railway station where the number of passengers dropped, we aim to present future tasks at the railway station where passengers have decreased. As a result, it was revealed that the railway station where the number of passengers has declined is affected by other railway stations and that the decline in living standards due to the decrease in commercial facilities becomes a problem. By comparing the amount of commercial facility accumulation in the vicinity of the railway station and the whole area, we could show the accumulation amount of the desired commercial facilities around the railway station. From the analysis, we made proposals on points to consider in future railway network development in the suburbs of Tokyo metropolitan area.
