BACKGROUND With an increasing proportion of the population living in cities, mass transportation has been rapidly expanding to facilitate the demand, yet there is a concern that mass transit has the potential to result in excessive exposure to noise, and subsequently noise-induced hearing loss. METHODS Noise dosimetry was used to measure time-integrated noise levels in a representative sample...

Public transportation in Makassar City is not yet well integrated, be it physical integration (routes and modal shift facilities), schedule integration, service (tariffs). The existence of a new mode, namely Sahabat Bus, considered to improve the condition public City, but instead takes over function existing city transportation. purpose this research first find out characteristics bus friend's...

noise is one of the major hazardous occupational exposures and one of the occupations at risk is the transportation industry. however, few studies have measured and reported the amount of noise exposure in drivers. in this study, we evaluated noise exposure among the public transportation bus drivers of one major iranian city, kerman, southeast iran. eighty public transportation buses in the st...

Brazil is a Federal South American Republic, in which there are 27 federated states divided into 5 regions and Brasília, the federal capital. In 30 years, the country has almost doubled its population. From 93 millions people in 1970 to 182 millions people in 2004. Nowadays, more than 80% of Brazilian population lives in the urban centers, from which 30% are concentrated on the Metropolitan Reg...

Nowadays the public transportation system like the metro are well advanced. Passenger safety, convenience and the need to improve the performance of existing public transportation is driving demand for intelligent transportation system in the market. The paper we introduce, proposes a novel fare estimation technique using Automated Fare Collection (AFC) System and Radio Frequency Identification...

There is ongoing debate over the relative advantages of rail and bus transit investments. Rail critics assert that cities which expand their bus transit systems exhibit better performance than those that expand rail systems. This study examines those claims. It compares public transport performance in U.S. urban areas that expanded rail transit with urban areas that expanded bus transit from th...

In this paper, a multi-perspective decision support system (MP-DSS)‎ ‎to design hierarchical public transportation network is developed‎. ‎Since this problem depends on different perspectives‎, ‎MP-DSS consists of two sub-systems with macro and micro sub-systems based on travel information‎, ‎land use and expert knowledge‎. ‎In the micro sub-system‎, ‎two sub-modules are developed considering o...

This study is an attempt to overcome the lack of reliable estimates on the willingness of Malaysian users to pay for public transportation (particularly buses) through a combined analysis of a fuzzy analytical hierarchy process (F-AHP) and the Taguchi method. This is a ground-breaking study in the attempt to evaluate the bus users’ satisfaction factors based on the F-AHP, and find the pattern f...

We optimize ordering and inbound shipment decisions for a manufacturer that sources multiple items from a single supplier. The objective is to satisfy the requirements in the production plan with minimum transportation and inventory holding costs over a multi-period planning horizon. Transportation costs are charged to the manufacturer on a per truck shipment basis. We investigate the option of...
