Truck Weight

Roads and bridges are designed to meet the transportation demands for traffic volume and loading. Knowledge of the actual traffic is needed for a rational management of highway infrastructure. There are various procedures and equipment for measuring truck weight, including static and in weigh-in-motion techniques. This paper aims to compare four systems: portable scale, stationary truck weigh station, pavement weigh-in-motion system (WIM), and bridge weigh-in-motion system (B-WIM). The first two are reliable, but they have limitations as they can measure only a small fraction of the highway traffic. Weigh-in-motion (WIM) measurements allow for a continuous recording of vehicles. The presented study database was obtained at a location that allowed for recording the same traffic using all four measurement systems. For individual vehicles captured on a portable scale, the results were directly compared with the three other systems’ measurements. The conclusion is that all four systems produce the results that are within the required and expected accuracy. The recommendation for an application depends on other constraints such as continuous measurement, installation and operation costs, and traffic obstruction.

In an era of budget deficits and financial cutbacks, the efficiency of state highway finances dictates future investment in road construction and maintenance. Considering the significant impact of highway infrastructure on the survival and competitiveness of the logistics industry, this paper aims to develop a meaningful set of benchmarks that will guide the state government authority in making wise investment decisions regarding road construction and maintenance. In particular, we propose a data envelopment analysis that is proven to be useful for measuring the operational efficiency of various profit or non-profit organizations. Using the examples of state highway finances for Kentucky and other comparable states in the United States, this paper illustrates the usefulness of data envelopment analysis for the efficient allocation of financial resources to road construction and maintenance.

<p><em>The </em><em>cross of Semarang – Magelang – Yogyakarta along</em><em> </em><em>± 130 km is now connected to the highway infrastructure. This condition makes the highway based on </em><em>the </em><em>road be the only alternative modes of transportation used by people to travel. This </em><em>condition </em><em>makes some roads that cross Bawen –</em><em> </em><em>Ambarawa – Magelang – Yogyakarta experienced a density that resulted </em><em>in</em><em> congestion. The government has a policy to reactive the railroad that once operated as a mode of transport cross Semarang-Yogyakarta. If this policy is implemented, people will have a choice of alternative modes of transportation. The study aims to assess people's preferences and attitudes related to the government policies reactivation of the rail lines cross Semarang – Yogyakarta. This study was conducted using a mixture of qualitative and quantitative research. The analysis was performed by descriptive quantitative and qualitative methods, which is after scoring the analysis results obtained community preferences, cross tabulation analysis and continued with qualitative descriptive analysis. T</em><em>his </em><em>study finding </em><em>is</em><em> the variables such as travel costs, travel time, accessibility and qualitative attitude (comfort, security and safety) have</em><em> </em><em>relationships with community preferences to switch to using the railway mode. Then, when the public preference </em><em>is compared</em><em> with the attitude of the government, the result is </em><em>there is a</em><em> match between the preferences of </em><em>public </em><em>and the government's attitude </em><em>for the</em><em> </em><em>qualitative attitude </em><em>and accessibility</em><em> variables</em><em>. However, travel costs and travel time </em><em>variables are</em><em> </em><em>the </em><em>mismatch between what the preferences of the community with what the government's position.</em></p>

The Temple

<p>Off the coast of Paraparaumu lies one of New Zealand’s most iconic tourist attractions, the Kapiti Island nature reserve. Home to many native plant and wildlife species, this island sanctuary offers a unique nature experience that is under appreciated. The now flourishing nature deserves to be honoured a respected by locals and tourists of the Kapiti region. To date there is no designated building where ticket purchases and bio-security checks can be undertaken for island visitors. No obvious link exists from the local shops to the beach front where the visitors depart. This presents an opportunity for a gateway building to create a slice of the Island’s nature on the mainland. In doing so this would honour and celebrate the sanctuaries nature, installing a level of reverence for the island as visitors pass through.  This thesis looks to explore the possible synergies between nature, highway infrastructure and religious architecture types. In order to develop a critical understanding of each architecture type and the possible synergies, explorations involving mass, volume and symmetry were conducted. These specific qualities put the project into a tradition of monumentality. As an understanding of this tradition developed Louis Kahn became an important precedent for me. Just as the late Louis Kahn achieved presence in his buildings, I argue that monumentality could be used in developing a successful synergy between infrastructure and religious architecture types. In the same way monuments and temples typically evoke respect I believe a monumental building on the Paraparaumu beach front will install a reverent homage towards nature as visitors to the island pass through.  Throughout this thesis the series of design experiments involving traditional monumental qualities explore the synergies between nature, highway infrastructure and religious architecture types. The exploration utilizes the gateway building as a project to test the possible synergies in context . Operating within a design-led research methodology, varied approaches using multiple mediums explored formal language, spatial experience, composition and proportion of monumentality.   The final design, situated on an existing roundabout, is a cylindrical concrete temple connecting the shop and beach front. The form is a subtracted mass obtained through an exploration of subtraction and composition. This temple evokes the desired homage towards nature as its visitors pass through to the island. Although grand in size, I argue, because the temple is situated on a traffic island, the over bearing power of monumentality is played down, respecting its surrounding context. As the design process unfolded a shift occurred in the preferred method for experiments. In the early stages a reliance on a digital experimentation method existed, however a shift towards an analogue experimentation method occurred as an understanding of monumentality and possible synergies between nature, highway infrastructure and religious architecture types were realised. This shift in methodology, required more precision and rigor for each experiment, invoking a deeper understanding of each success and failure. Critically reflecting on this transition forms the discussion of my thesis, understanding the opportunities of Paraparaumu and how a modestly scaled building can be developed that still imposes its significance in the surrounding context.</p>

Desert Highway

With the rapid development of economy, highway infrastructure is gradually extended to desert region. But at present, affected by the special engineering geological environment in desert areas, the work must be majorly planned and considered before the highway project is set that how to reduce the construction cost while ensuring the desert highway construction quality, and maximizing the maintainance and further improvement of desert environment. The wind and sand environment characteristic of desert areas is analyzed in this paper, then the common types of desert highway subgrade slope are investigated and the stability of wind-blown sand subgrade slope is studied, finally the theories and methods according to the characteristics of the desert subgrade are proposed.
