Abstract

Zonal trip generation is usually assummed to be influenced only by demographic and economic variables. It is seldom to consider spatial position of the zones as an influence variables to its trip generation. In actual condition, people will consider strategic position of residential area when they choose to buy or rent of their home, in accordance with their place of activities such as working, studying for their children and shopping. This research aim is to calculate the influence of spatial position of residential zones from the activities centers to zonal trip generation in Surabaya, Indonesia. Surabaya has several activities centers that can be classified as urban centers and suburban centers. In order to define position of residential zones in relation with activities centers, travel time is defined as a spatial measure which can be measured using Google Maps. Trip generation data is compiled from origin-destination matrix from household interview survey. Regression analysis is used for calculation of the influence of spatial position of residential zones in relation to the activities centres to zonal trip generation. The result shows that travel time to urban center influences reduction of the residential trip generation more than travel time to suburban centers does. However, still many trips were not influenced by travel time from residential to city center since housing ownership in Surabaya is fixed system more than flexible one, and housing at periphery area much cheaper than at city center.

Abstract

Falling Weight Deflectometer, FWD, is the most popular equipment used to measure the deflection of  flexible pavement in Indonesia. The loading used during application of the FWD equipment generally correlates directly with those of the loads of standard heavy vehicles. Therefore, the resulted pavement deflections obtained from the tests should be also suitable for highways traversed by standard normal vehicles only. This may not be the case for highways in Indonesia, where most trucks are highly overloaded, so much beyond the allowable standard loads. The existing method of FWD test may not be representative anymore to measure the actual pavement deflections under highly overloaded vehicles. In this paper, the authors describe their findings about deflections of flexible pavement when the pavements were subjected by heavily overloaded vehicles. The first step is to modify the FWD equipment with larger falling distances and heavier loads to simulate the highly overloaded vehicles in Indonesia. Based on the results and by using statistical approach, a new mathematical equation can be derived to reflect the functions of actual pavement deflections under much higher loads when compared to those of standard normal load. Therefore, using this new equation one can predict the actual pavement deflection under highly overloaded vehicles, by just performing standard FWD test of standard loads on the pavement, so that the design of overlay thickness can be modified accordingly to be applicable to overloaded traffic in Indonesia.

Abstract

The movement of aircraft and passengers at Juanda international airport is increasing every year. In 2012, the air side infrastructure of Juanda airport almost reached the maximum capacity. In other side, PT. Angkasa Pura I as the operator of Juanda airport had planned to revitalize the Juanda airport terminal that located on the south side. This terminal was not operated for 8 years. The pavement of taxiway should be evaluated its strength. The evaluation method compared The Pavement Classification Number (PCN) of taxiway pavement with Aircraft Classification Number (ACN). If PCN value was higher than ACN value, so the taxiway pavement could serve aircraft movements. The pavement of taxiway on Juanda airport evaluated by using software COMFAA. Data input into the software COMFAA was the existing pavement structure and the movement of the aircraft that will to use south side of Juanda Airport Terminal. The scenario 1 result is the exiting pavement should be overlaid 7 inches to support The operational of Terminal 2 Juanda Airport. In other side, scenario 2 result showed that the existing taxiway pavement structure was able to hold the load of aircraft movements over 20 years. The PCN value is 80.2 dan the ACN values are 89.3 in the scenario 1 and 75 in the scenario 2.
