Analysis of roughness performance of chloride-stabilised rural roads

ABSTRACT Rural roads play a crucial role in the economic and social development of societies. Therefore, they should be managed accordingly and supported by consistent public policies and suitable management practices. Maintenance requirements and costs depend upon the desired serviceability expected for the prevailing traffic, which can be estimated from the road roughness. Given the increasing use of chloride stabilisers to improve the service level of rural roads, it is crucial to objectively assess the performance of these roads over time to perform life-cycle cost analyses for effective management. The objective of this study was to assess the roughness of chloride-stabilised rural roads over time and to propose a performance model from the analysis. As a result, a model for roughness prediction of chloride-stabilised roads was developed and successfully validated, considering an exponential estimation curve based on the age of the road. The proposed model is statistically significant, considering a 95% confidence level range of IRI predicted ± 0,88 m/km. This result indicates that age provides confident information about the IRI. This model is proposed for network-level management of rural roads in terms of IRI.

Improving the Efficiency of the Regional Road Services – Middle Euphrates Region

Services are one of the important indicators that reflect the welfare of the society and its development. Due to the increase in various means of transport and the increase in internal and external traffic, the provision of basic services for the regional road users has become a necessity that should be studied in a thorough and accurate manner to reach the appropriate mechanism for the spatial allocation of these services. The research problem lies in the lack of interest in the optimal spatial allocation of the public road services because of the overlap between the powers and authority of the municipalities and the directorates of roads and bridges preventing to study the subject comprehensively. In addition, there is a lack of roads in general and regional roads in particular for service stations and passenger vehicle stopping spaces, with standard specifications. Therefore, this research is aimed at identifying the sufficiency of spatial allocation of regional road services and studying the current situation of these services, analyzing the efficiency of these services and finding the shortage. We also set plans and strategies to develop the level of services and invest in a manner that achieves the required sufficiency. Furthermore, some research hypotheses were set: the sufficiency of the spatial allocation of the public road services in the regional roads improves the road level of service by identifying a set of factors that directly affect this sufficiency.

Passenger car equivalents for urban roads using average time headway of car following conditions

Passenger car equivalents are used to calculate capacity and evaluate service level of urban roads. This article uses the average time headway of different car following conditions to replace the total average time headway of road vehicles, and the proportion of large vehicles to improve the headway method. This article analyzes the influence of several factors such as the proportion of large vehicles, road attributes, and traffic flow on passenger car equivalents, and obtains the following conclusions: (1) the behavior of vehicles crossing the opposite lanes has an important influence on the passenger car equivalents of the road; (2) passenger car equivalents of vertical sections at the center of central isolation belt are different from those at the start of the road; (3) the road attributes affect the passenger car equivalents; and (4) the passenger car equivalents of heavy vehicles on roads that allow two-way crossover are less than the specific value, however, the passenger car equivalents of heavy vehicles in the road segment without two-way crossing-line are greater than the specific value.

Simulation of Voluntary TDM scenarios on road service level in corridor of Nicolau dos Reis Lobato-Kolmera, Timor-Leste

Nicolau dos Reis Corridor Lobato-Kolmera is one of the corridors in the center of Dili City with the dominance use of office, trade and services activities. This effects a high trip attraction, so the level of road service in this corridor starts to be unstable especially during peak hour. At present there is no policy to deal with congestion issues in terms of managing travel demand. Therefore, this study aims to develop Voluntary-based Travel Demand Management (TDM) scenarios that can improve road service in the Nicolau dos Reis Lobato-Kolmera Corridor. Scenario is developed through simulation of multiple linear regression models and calculation of degree of saturation (DS). The results show that the TDM scenario in the form of Vanpool is considered more effective in improving road level services compared to Carpool and Flextime scenarios. The scenario of Vanpool and Flextime can be developed in office activities, while in trade and service activities require a combination of Carpool and Flextime policies to significantly reduce DS values.

Effect Of Age To Overload The Road

quality of the transportation system in an area is determined by the level of road service that is passed by each vehicle, both light vehicles and heavy vehicles that exceed the overload of the specified class of roads, all of which result in damage to the road faster than the planned age at the beginning of the plan. In this paper, we will see the extent of vehicle overload with the age of road pavement using the Bina Marga 2002 method. The equivalent number is calculated and N (ESAL) is calculated under normal load conditions and overload. So that it can be concluded how the influence of vehicle overload on the age of road pavement. In this final project, it can be seen, for example, by overloading 10% for medium trucks 16 (tons), trailers 34 (tons) and trailers 54 (tons) affecting the percentages of age to 86.455%, 92,515% and 97,858%. For the combination of the three vehicles with an overload of 8%, it affects the percent of planned life to be 92,242% from 100%. So that it can be concluded that the overload of vehicles on road pavement is very influential on the reduction in the age of road pavement so that it can be expected that road users need to comply with existing traffic regulations.

A theory of auto ownership rationing

This paper provides a theoretical analysis of three alternative auto ownership rationing schemes, including lottery, auction and the hybrid scheme. The city's residents are differentiated by their income level, which is assumed to follow a uniform distribution. Expected social cost minimization models are proposed for determining the optimal auto quota for these schemes and the optimal proportion allocated to the lottery and auction in the hybrid scheme. The solution properties of the proposed models are analytically explored, and a comparison of these schemes is made. The results show that the auction scheme is most efficient and the lottery scheme is most inefficient in terms of the expected social cost. The optimal auto quota increases with degraded transit services, but decreases with increased auto travel time/cost. Increasing the proportion of allocation to the lottery in the hybrid scheme may lead to an increased or a decreased optimal auto quota, depending on the road service level. Residents' income gap can significantly affect the optimal quota solution: widening the income gap via raising the income of the rich pushes the government to increase the quota to be provided. However, narrowing the income gap via raising the minimum salary standard may require an increased or a decreased quota provision. The efficiencies of the lottery and auction schemes are very close in terms of the expected social cost, which justifies the use of the lottery scheme in practice.

Traffic Structure Optimization in Historic Districts Based on Green Transportation and Sustainable Development Concept

To perform the reasonable traffic structure in the historical districts and effectively alleviate the contradiction between limited traffic supply and rapid growth of the traffic demand in historical districts, a dynamic game model of traffic competition is established in this paper, aiming at the green transportation and sustainable development. Firstly, the logit model reflecting the sharing rate of the traffic mode is established by using the generalized cost method to quantify all the factors that influence the travel mode selection. Accordingly, a dynamic game model of complete information is established for the trip mode of historical districts, taking into account the economic sustainability, environmental sustainability, and social sustainability of the traffic development. The model is based on the goal of maximizing the generalized profit, and modeling with environmental pollution, energy utilization, and road service level as the common constraints of various traffic modes. By iterating the Nash equilibrium solution of the model, the optimal structure and the optimal share of the traffic modes in the historical districts can be predicted. Finally, the model presented in the study is verified by the historical districts of Academy Street in Zhengzhou city, China, and the optimal structure and optimal traffic share of each traffic mode in the block are obtained. By changing the constraint conditions of the model, two sets of different governance policies are compared and analyzed, and some feasible suggestions on improvement of traffic structure are also put forward. The research results can be the important reference for traffic planning in historic districts.
