An iterative process, combining a macroscopic simulator and a set of the traffic demand-change estimation models, is developed to estimate the traffic demand at work zones in urban freeway corridors. The process is designed to capture the interaction between work-zone conditions and traffic diversion in determining the traffic demand approaching the entrance and exit ramps at a given work zone. The proposed models and process were calibrated and tested with the field data from the work zones in the Minnesota metro-freeway network. The test results indicate promising possibilities of the proposed process in terms of the estimation accuracy and transferability of the demand-change estimation models developed in this study.

This paper discusses the formulation of a stochastic Vehicle Routing Problem (VRP) process, introduced to existing deterministic VRP process, directing all efforts towards the dynamical situations that occur in a typical VRP setting as it applies to everyday real-life situations. It contrasts the dichotomy between static and dynamical situations in VRP, constructs and analyzes the relationship between static and dynamical situations in Vehicle Routing Problems, formulates an expression to describe the dynamical situation in VRP and relates the problem formulation to existing VRP with a view to solving the problem as it applies to real-life situations, a major trend in the business world today. With a view to achieving these, this paper associates the merits of reactivation of route, re-optimization of operation process and projects an anticipatory demand for a dynamical situation in VRP with stochastic requests via three stages: Pre-Decision States, Decisions States and Post-Decision States. First, as a reaction to anticipatory customers’ requests, the current routing plans need to be re-optimized and current customers’ request reactivated. Second, potential future requests need to be anticipated along current decision making since life itself is dynamic. Decisions need to be made in good time. Though, the limited time frame between when a vehicle leaves and returns to the depot often prohibits extensive optimization in both dimensions rather, answer the questions that arise on how to utilize the limited time effectively and judiciously, satisfying both the current and anticipatory customers equally.

Optimum utilization of time after an accident which is golden hour serves as a measure of effectiveness of ambulance service management system to reduce the loss of life and property. This paper presents a case study on Arada sub-city which is the oldest of all sub-cities located in the central part of the capital Addis Ababa with 11.56 Km2 area wide. Its population, which is around 212,009, is highly dense and its spread of population density is about 18340 people per Km2. In the study area, the existing road network condition is not developing in line with the population growth. Accordingly, at time of disaster, the responsiveness rate of efficient ambulance transportation services to the right target area is low and unsatisfactory to level of customer’s satisfaction. Therefore, the purpose of this study is to conduct road network analysis in Geographic Information System (GIS) environment for the betterment of ambulance transportation service in the sub city. A detail GIS database of the road network, ambulance location, accident locations and hospitals was prepared using Arc GIS software with the extension of network analyst. In this study, one ambulance station, three accident locations and six hospitals were used to compute 1, 2 & 4 minutes service area and best route analyses. The impedance value 1, 2 & 4 minute corresponds to very urgent, moderate urgent and low urgent service areas respectively. In very urgent service area domain about 33% of health centres are found whereas in moderate and low urgent service area domains about 65% and 100% of health centers are found respectively. This implies that, the current option increases health center service area domains by 34% from the existing approach. Besides, the selected sample best routes of ambulance transportation service are computed in terms of travelling time in minutes and its fuel consumption in litters. Accordingly, the estimated travelling time of the selected sample best route is about 870/30482.20 and 1138.5/3772.16 minutes/ birrs annually. This implies that, the proposed study decreases a total travelling duration and cost by 268.5/723.96 minutes/ birr from the existing one. As a result, GIS-based ambulance transportation service proto type model was developed.

The Arba Rekete-Gelemso gravel Road section is affected by the presence of expansive soil, this soil has shrinking and swelling behavior due moisture fluctuation. The main objective of this research work is to investigate the Characterization of Borrow materials for embankment fill and capping layer based on their index and strength properties for Road Construction of the proposed route. In order to achieve the objectives, field investigation and nine (9) samples were also collected from the identified borrow area and laboratory test analysis were performed such as, Atterberg limits, compaction, CBR and percentage of swell tests. ERA‘s and AASHTO’s standard technical specifications have been used to interpret the data by integrating the field with laboratory test results. The subgrade soil of route, having liquid limit value greater than 60% and plastic index value greater than 30% and CBR value less than 5%, at Chainage km 0+000-4+000, 5+900-8+000, 9+400-12+900, 13+500-14+000, 15+000-16+000, 17+100-17+600, 18+500-20+500, 21+500-34+900, and 35+200-47+000 unsuitable. The index and strength properties of the borrow materials fulfill the requirement for embankment fill and subgrade improvements. Finally, all unsuitable subgrade soil along the study route corridor are recommended to remove and replace with suitable and non-expansive subgrade materials, since enormous amount of selected fill materials that fulfill the requirements for subgrade soils improvement are available nearby the study area.

Passenger demand and transport work are the basic quantitative indicators of the effects achieved in public road passenger transport activities. The research is conducted to determine the need for managing the transport system and planning its further development. The aim of this paper was to determine the dynamics of development of these two sizes in the seventeen-year period from 2000 to 2016, and to use them to develop a prognostic trend model for the future period. Furthermore, the correlation analysis determined the relations between traffic and economic quantities, and the road transport system was compared by mathematical and statistical parameters with all other traffic systems of the Republic of Croatia, in order to determine its share and importance in the Croatian public transport system. Based on the analysis conducted for passenger demand, a future downward trend is projected. Future trends will be identified for transport work based on the developed trend model and correlations between transport and economic sizes. Furthermore, the road transport system accounts for the largest share of transport work and passenger demand in the Croatian public transport system.

Bituminous mixes for flexible pavement construction are most commonly used all over the world. Mainly aggregate, sand, bitumen etc. are used for pavement construction. In this investigation an attempt is made to study the properties of bituminous pavement materials by the partial replacement of spent foundry sand as fine aggregate with an increment of 10%. Foundry sand is a high quality silica sand that is used to form molds for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass etc.) metal castings. Metal casting industries use huge quantity of foundry sand every year and disposed them after being used. This industrial waste occupies large amount of space of the land. If this sand can be utilized in pavement construction, the disposal and pollution problem can be minimized. The main objective of this study is to determine sufficient bitumen content and mix stability to ensure a durable and cost effective pavement after being partial replacement of foundry sand. The proposed mix design will be conducted in accordance with Marshall Mix design. After performing the experimental investigation it is found that for 30% replacement of waste foundry sand provide superior field performance and better stability than the conventional mixes.

Productivity at the berth is one from the group of port productivity measures which is closely tied to ship turnaround times. Net berth productivity is value of productivity related to the operational time at the berth. Based on the facts identified from available literature about minor share of researches related to the net berth productivity in the handling operations with dry bulk cargoes in a seaport, it was decided to take this port productivity metrics as an object of a research. After a detailed analysis of different categories of the net berth productivity in the handling operations with dry bulks, key groups of influential factors which determine values of the net berth productivity are identified and systematized. Some principal elements related to improving net berth productivity are taken into consideration, too. Concrete results shown in this paper are related to the Dry Bulk Cargo Terminal in the Port of Bar (Montenegro).
