Parking Requirement of Shopping Centers

Published Online: 27 Dec 2021
Page range: 1 - 9

Abstract

Abstract

The parking problem is a severe challenge in city planning because of its impact on road congestion and accidents, delay time, and cities’ economy. therefore, many cities conducted different studies, reports, and projects to find the number of parking generation as it related to land use, in form equations, rates, and even data plots by using different independent variables. Iraq, till now, does not have a comprehensive study of parking requirements, or in specific how many parking spaces the different land uses are generated or needed. The general situation in Baghdad city at present is inadequate public transportation, few transportation alternatives, large private car use. besides the high illegal parking on the roads which means higher traffic density and congestion roads. this research studies three different shopping centers in Baghdad and analysis their parking generation as related to three different independent variables. these variables are GFA, GLA, and entertainment percentage where each variable is analyzed separately. the analysis was done based on parking accumulation in these sites. as it was counted manually for three days for Parking counting time that selected according to the peak of visitors for Retail is from 4 pm – 11 pm. in a result several parking generation rates and models with different forms are developed by using simple linear regression and only the best of them that has high R2 value and low RMSE is recommended. from the conclusion, the GFA and GLA have the most significant effect on parking generation as they developed strong models and rates. as these rates are 4.1 and 4.57 parking spaces for each 100 m2 of GFA and GLA respectively.

Proposal for a New Concept of Night Transport in Urban Transport Žilina

Published Online: 27 Dec 2021
Page range: 10 - 15

Abstract

Abstract

Night urban transport in Slovakia is realized by public transport only in selected regional cities. In the long run, due to the increasingly available taxi services and the lack of connection between rail transport and night public transport, it has a declining share in passenger transport. A new operation proposal is necessary for the regional city of Žilina, which considers not only the factor of continuity, but also other factors, such as economical operation and travel expenses. The main task of the article is therefore to propose a more usable concept that will attract as many satisfied passengers as possible to this segment of public transport.

Possibilities of Building Connection of M.R. Štefánik Airport to the ŽSR Network

Published Online: 27 Dec 2021
Page range: 16 - 22

Abstract

Abstract

The current conditions of the railway infrastructure near the M. R. Štefánik Airport is analysed as unsatisfactory. The current form of the railway infrastructure of the monitored area is not adapted to the creation of a suitable place for boarding and alighting of passengers. The point determined for boarding and alighting of passengers must be at a reasonable distance from the M. R. Štefánik Airport terminal. This distance must be able to be overcome by walking so that it is not necessary to use another mode of transport to move between these places. The article deals with the possibilities of connecting of M. R. Štefánik Airport to the ŽSR network. The basis for the proposal to connect M. R. Štefánik Airport with a suitable infrastructure ŽSR network within the framework of railway passenger transport is the determination of a suitable transfer point. One of the logical priorities is to place the transfer point as close as possible to the air transport terminal of the M. R. Štefánik Airport within the space possibilities and technical conditions.

Design of the Power of an Electric Lifting Motor for a Single Girder Bridge Crane with a 500 Kg Load Capacity

Published Online: 27 Dec 2021
Page range: 23 - 29

Abstract

Abstract

An electric hoist could be considered as the most important component of an electric overhead crane. Electric hoists are material handling equipment used for lifting, lowering, and transporting materials and products. They are powered by an electric motor and have a controller to adjust the lifting parameters. Three-phase induction motors are most often used as electric lifting motors for bridge cranes. This paper concerns the design of the power of the electric lifting motor for an electric hoist of the single girder bridge crane with the 500 kg load capacity. It represents the design of the electric lifting motor according to a commonly used scheme for the design of electric motors, from the power at a uniform load to the relative load of the motor. Based on the input data, the necessary motor parameters are calculated using Microsoft Excel. The main parameter is the static power of the motor, the calculated value of which is 0.823 kW. Based on the value of this power, a three-phase induction motor 1.1 kW, MS90-4 is selected. This electric lifting motor is suitable for the above-mentioned bridge crane, as it meets the condition of torque overload.

New Railway Tunnels and their Construction Method as Well as their Impact to Train Operation

Published Online: 27 Dec 2021
Page range: 30 - 33

Abstract

Abstract

As the modernisation of the cities, railway road construction and modernisation of existing lines are demanded during the past decades more than before. Demand of short travel time is one the reasons that we redesign of existed railway roads and modernisation process. Tunnel construction is one the ways that we can shorten travel time in the existing railway roads. In this study, we introduced one of the commonly used tunnel construction methods, New Austrian Tunnelling Method (NATM), and some of important points of that method regarding tunnel excavation and bearing capacity of excavation support system. Furthermore, we gave some information about some tunnels which shortens the travel time and some tunnel project examples which are constructed with this method. The main purpose of construction of all these tunnels are to shorten the travel time of the existing railway line due to increasing on population and urbanization.

Driving Duration Difference in Road Freight Transport Between Vehicles Up to and Over 3.5 Tonnes

Published Online: 27 Dec 2021
Page range: 34 - 40

Abstract

Abstract

Working conditions for drivers in the European Union and Slovakia are governed by European and National regulations. Regulations lay down rules on driving times, breaks and rest periods for drivers of lorries and buses to improve working conditions and road safety. There is no doubt that with increasing freight performance, the number of carriers and vehicles in the field of road freight transport is also increasing. Therefore, in connection with the current EU legislation, which aims to increase road safety, attention is paid to adopting regulations for all road haulage operators and carriers. The purpose of this paper is to show difference between road freight transport performed by vehicles up to 3,5 tonnes and vehicles transporting goods where the maximum permissible mass of the vehicle, including any trailer, or semi-trailer, exceeds 3,5 tonnes.

Examination of the Share of Medium and Heavy Trucks in the SR

Published Online: 27 Dec 2021
Page range: 41 - 45

Abstract

Abstract

The state of the environment is deteriorating due to human activity. Today, almost no major international forum can avoid addressing environmental issues. Environmental protection has therefore become a mandatory issue for every responsible politician. In addition to contributing to economic growth, the role of road transport should be to ensure sustainable transport and solutions for people and goods around the world. The European Parliament has adopted Directive 2019/1161 on the promotion of environmentally friendly and energy-efficient road transport vehicles, which defines the obligations and forms of support for the procurement of environmentally friendly vehicles. In addition to these transport tasks, there is also a challenge to reduce CO2 emissions in transport through the use of new technologies in transport. Also in road freight transport, there are currently vehicles that use alternative fuels with a more favorable environmental impact. In connection with the current EU legislation, which aims to increase the share of these vehicles, attention is paid to the contribution of this area, analysis and examination of the current situation with trucks with alternative propulsion.
