Abstract:Airport curbside, where travelers and their baggage enter and exit the terminal, and the designated parking area are important components in airport land-side facilities. Passengers expect safe and efficient roadway operations even as volumes increase, but the design and capacity of the curbside are often constrained by the terminal building and the proximity of on-airport land-side infrastructure. The operating characteristics of airport terminal curbside differ significantly from those of most other roadways due to several reasons such as vehicle dwell time, maneuver vehicles to and from adjacent lane, variation in demand etc. The capacity of a curbside roadway is defined both by the number of vehicles that can be accommodated while stopping to pick up or drop off passengers and the number that can be accommodated while traveling past the curbside in the through lanes. Therefore a study of operations at curbside and parking area is important to identify issues related to existing and future demand levels.The main focus of the paper is on the evaluation of vehicle operations and passenger behavior at the BIA terminal access roadway, weaving segment, arrival and departure curbside roadways and terminal car park. Analysis of vehicular traffic, travel mode choices, and curbside roadway vehicle queues, vehicle dwelling times, passenger occupancy time at curbs and passenger processing and walking times will provide useful information for developing plans for operational improvements as well as for future expansions. Using the available data, the demand and the capacity at these facilities are evaluated to estimate the existing level of service. In addition, measures were identified to improve the operational efficiency of these facilities and design improvements are proposed to ensure good operational efficiency for the forecast future demand.
This study utilizes the most recent data set available on Bandaranaike International Airport Curbside Operations, collected in 2012, in assessing the curbside roadway level of service. The level of service of both the departure and arrival curbside roadways are evaluated using the guidelines presented in the ACRP 40 report on Airport curbside and Terminal Area Roadway Operations. This study compares the two evaluation procedures suggested in ACRP 40 where only one vehicle type is assumed and where the actual vehicle configuration is taken in to account and the factors affecting the differences are discussed. Upon unavailability of an exact method/function to obtain the factor to derive design stall requirement from the calculated stall requirement, an appropriate function was developed to predict required values in the calculation. The LOS of the BIA for the given data set was derived as E for both arrival and departure curbs which is different from the previous study done by Sameera using the same data set. Consideration of the vehicle configuration found to have affected the difference of the outcome mainly. The through lane level of service did not affect the outcome.
Provincial level and Local roads comprise nearly 50% of the road network in mileage in Sri Lanka. They play a pivotal role in providing access to the local communities especially in rural areas and an essential component of the economic development of those areas. These roads are under the purview of Local Councils and Provincial Road Development Authorities. Most of these roads do not conform to the design guidelines as they were often developed from local foot paths or gravel roads. Therefore, the travel speeds are very low and safety issues have arisen with the increase in travel demand and the use of motorized vehicles. Therefore, there is need to upgrade these roads to the appropriate design standards to ensure safe and efficient mobility to the road users. However, the road agencies have limited funding to implement upgrading projects on the entire network. Thus, it is pertinent that there is a methodology to prioritize the roads based on the current operational performance so that the funding allocation can be done in the most effective manner. Road upgrading in the context of the study is focused on roadway improvements such as alignment, road width, shoulder etc. In addition to the limited funding, the agencies also lack the technical capacity to carryout detailed investigation and surveys on highway performance that are typically carried out in other road agencies at national level. Therefore, the study proposes a simplified methodology to evaluate the performance index of the road based on its roadway and operational characteristics, to be used to assess road network condition and identify upgrading needs for a highway agency of a low volume road network. Index Terms-Highway performance index, provincial roads, developing country, level of service. II. EVALUATION OF HIGHWAY FUNCTIONAL PERFORMANCE Highway performance relates to the structural and functional performance of the road. Functional performance is represented by the mobility, rider comfort and safety. These are predominately affected by the roadway characteristics such as alignment, gradient, curvature, road width, shoulder condition, surface condition; and operating characteristics such as traffic volume, heavy vehicle composition, presence of non-motorized traffic etc. Most studies represent highway functional performance via level of service which mainly addresses the mobility aspect of the road.
