The 1960S

The golden age of road demand modeling began in the 1950s and flourished in the 1960s in the face of major road construction needs. These macro models, as well as the econometrics and the data to be processed, were provided mainly by engineers. A division of tasks can be observed between the engineers in charge of estimating the flows within the network and the transport economists in charge of managing these flows once they are on the road network. Yet the inability to explain their decision-making processes and individual drives gave some room to economists to introduce economic analysis, so as to better understand individual or collective decisions between transport alternatives. Economists, in particular Daniel McFadden, began to offer methods to improve the measure of utility linked to transport and to inform the engineering approach. This paper explores the challenges to the boundaries between economics and engineering in road demand analysis.

Economic Developments

High-type roads in Tanzania have been predominantly of asphaltic concrete construction. This ever enlarging and ageing asphaltic road network represents increasing resource requirements on the road agency in the form of maintenance. Limited resources coupled with the ever sky-rocketing costs of petroleum products and the competing demands of social economic developments, presupposes the need to look for alternative road construction technology that is more cost-effective and resource optimising. Experience gained from developed and some developing countries where concrete pavements have been widely used suggests the potential of this type of pavement in many developingcountries. This paper discusses the technical aspects of design and construction- and maintenance-related aspects of concrete pavements. The discussion extends further to highlight issues pertaining to the performance of concrete pavements and strategies for promoting the use of concrete pavements in Tanzania. Conclusions and recommendationsare made with suggestions on how to start implementing the proposed strategies.

<p>The literature on life satisfaction in transition countries, and in particular on Romania, demonstrated that life satisfaction significantly differs across rural communities and cities of different size. The question addressed in this paper is whether these imbalances are stable over time or, instead, they become manifest in the presence of strong divergences in the economic growth rates of different kinds of communities. Results point out that in the period of sharp economic growth led by large urban areas, as the one experienced by Romania on the road to EU accession, rural/urban disparities in life satisfaction widened, favoring cities of intermediate size.</p>

In Indonesia, the road construction has experienced a fairly good development. From a wide range of road constructions, flexible pavement is the most chosen one because its characteristics: easy, fast, and efficient. However, flexible pavement has many weaknesses, for example the premature damage on the road surface after some time passed by the traffic so that the road cannot reach the planned age. For that, it is done a research to add a hot asphalt mixture material that aims to improve the quality of the mixture results. The selected ingredient is natural water hyacinth. The method used is trial and error with reference of SNI 03-1737-1989. Variations used are 2%, 4%, 6%, 8% and 10% of the asphalt weight, asphalt level used is 5.72 %. Of the 5 variations of mixture used on Type XI Asphalt Concrete Layer, it is obtained the result that the water hyacinth fiber level which has the best score and meet the specifications of SNI 03-1737-1989 is on the percentage of 6% which obtained from calculation data using graphs and regression model where Marshall Stability is equal to 644,46 Kg, flow 3,39 mm, VMA (voids in the mineral aggregate) is equal to 13,83 %, VFWA (voids filled with asphalt) is equal to 65,35%, VIM (voids in the mix) is equal to 2,52 %, density of 2.31 gr/cc, and Marshall Quotient of 164.03 Kg / mm.

The article deals with modern directions of domestic and foreign smoothness research coverage on the roads.  The problem of causes changes establishing in smoothness coverage related to the irregularities in the procedure of road construction layers is highlighted. The research results of the trafficway smoothness and its causes deterioration analysis, performed by operation of roads and airfields laboratory at National Transport University on research road area H-18 around the city Buchach is shown.  By the research results the road profile is drawn and the detailed analysis of road topping smoothness changes during road operation is done. Samples at the specific points on the road topping is taken: in one place it is a transverse crack, in another – without noticeable defects. It is established that road profile hollows and transverse cracks caused by black layers uneven thickness along the road.

Security is always an issue both in individuals and communal attentions. Any forms of threats and crimes that occur in the village area of Karyawangi Parongpong, such as motor vehicle theft, violence, drug abuse, gambling, and others are caused by a lack of supervision from local authorities. The limitation of surveillance distance is one of the problems. Thus, an effective and appropriate security system in a place is indispensable. In this paper, the design of the security system using IoT modules and ESP32 Camera, will be elaborated for karyawangi Parongpong's village. The system secures a village environment by detecting an intruder on the road, triggering Passive Infra Red (PIR) sensor, capturing all activities with ESP32 camera, and then sending data to a smart mobile phone through with Telegram application. These service activities were aimed at the improvement of security systems and increase knowledge of technology advances for rural communities in the Karyawangi Village environment, especially in security systems based on IoT.

Abstract, in case of the construction of road in soft soil, it is necessary toconsider the use of materials around the road construction site, and not touse selected material which is imported from outside the road constructionsite. Thus, aim to overcome the difficulties of using selected materials, namely the difficulty to obtain the materials, the price of expensivematerials , the freight of material that could takes a long time period, highcost, and the use of materials that tend to be environmentally unfriendly. Itis very necessary to learn about the use of nonstandard additive materials, taken to the road construction site, but with the use of geotextilereinforcement. The research method used is a full scale method in the formof trial embankment, so that the performance of the road can be observedfor a long period of time due to the traffic and soil settlement. The resultsobtained is settlement that occur on the road from the combination ofordinary embankment material and local material, most frequently occuredin a larger percentage of ordinary embankment than the local material. While the visual value is relevant to the settlement in which a largerpercentage of ordinary embankment results in a better visual value, due tothe quality of the ordinary embankment material is better than the localmaterial.
