The aim of this study is to analysis the performance of Robinia pseudoascacia (black locust tree) to accumulation some of heavy metals and compared with the concentration of these metals in falling dust Yazd highway green belt. In order to an experiment was conducted as factorial based on completely randomized design with four replications.The results showed that the concentration of, ...

Urban joblessness and inner city deprivation are a feature of the late twentieth century throughout the developed world. This paper considers the effectiveness of spatiallytargeted programmes in creating employment in deprived urban areas. It begins by discussing the twin themes of “enterprise” and “localism” which have dominated the UK policy response to urban problems in the 1990s and goes on...

In every edition of the Highway Capacity Manual (HCM) until 2016, three levels capacity analysis were defined: operational, project and planning analysis. The level detail each is a function purpose, breadth access available information. Planning determines in earliest stages planning, when small amount data information available. procedure based on AADT forecast macro traffic simulation. Often...

Dynamic traffic assignment through analytical modeling and optimization has been widely accepted by the IVHS R&D community as a promising traffic control tool for understanding and relieving traffic congestion on conventional highways and city streets. Due to the completely controlled nature of AHS traffic, dynamic assignment of AHS traffic is even more promising. One added dimension of complex...

In line with the current development worldwide, the provision of public infrastructure in Malaysia is undertaken using the public-private partnership approach (PPP). This study explores the way in which accountability is demonstrated in Malaysian tolled highway sector. The study uses the case study approach to examine the implications of PPP arrangement on accountability in the tolled highway s...

This paper considers the second-best policy problem that arises when auto travel is priced below its marginal cost and there is a substitute mass transit mode. We analyze the problem by combining a model of a rail line based on Kraus and Yoshida (JUE (2002)) with the highway bottleneck model. The model involves a transit authority which optimizes, in addition to the fare, two dimensions of tran...

Abstract—In the previous airfield construction industry, pavements made of reinforced concrete have been used very rarely; however, the necessity to use this type of pavements in an emergency situations justifies the need reference to this issue. The paper concerns the problem of airfield pavement dimensioning made of reinforced concrete and the evaluation of selected dimensioning methods of re...

and refinement was usually complete after ten to fifteen cycles. The refined values of the parameters compared well with the Rossmann programme values, except for the effective atomic numbers, which were uniformly smaller than indicated by the Rossmann programme. The Hart hO1 values were used in the 2 /~. Fourier synthesis, although there may be some question remaining about the proper Z values...
