Book Description
Lifts are installed in the buildings to satisfy the vertical transportation needs of their occupants and visitors. They are necessary to provide a comfortable means of transportation to the different levels in a building. Lifts play major role and provide a great deal of influence to the total function of a building, especially if the usage and numbers of elevator is not properly planned. The lift shafts are not easily modified in later stages of building development. Therefore the fundamental elevator design must be planned at the very beginning. The main objective of this project is to study the passenger lift traffic performance in office buildings. Six office buildings were visited. They are two in Putrajaya and four in Kuala Lumpur. The analysis was concentrated on the buildings with Elevator Management System (EMS). The EMS was used to capture the lifts performance data. The data were analysed based on the average waiting time (A WT) and the lifts traffic pattern. This study also was focused on the lift arrangement in the office buildings and zoning of the lifts. There is no specific law controlling the lifts quality of service. Poor quality of service can cause bad image, high maintenance cost and can affect the building reputation. Building management will receive many complains and tenants will find another place for better quality of service. Result shows that the most importance criteria for lift quality of service is the waiting time. Waiting too long for lift can make people irritable i.e. waiting time more than 30 seconds. This can encourage vandalism and can cause lift to brake down. It can affect the lift safety and in worse case it can cause fatalities.

Book Description
Vertical transportation systems (elevators, lifts, escalators and passenger conveyors) are used in almost all buildings of more than a few stories high. Traffic design and control, namely the movement of people by natural and mechanical means, need to be planned carefully as the costs of under- or over-provision are considerable and changes are not always possible. The subject is covered in four sections. The basic principles of circulation and an introduction to lifts are set out at the beginning, and then traffic design methods are outlined, followed by an examination of analysis and control. The sections are complete in themselves and are presented in depth, with worked examples and case studies as appropriate. The latest analysis techniques are set out, and the book is up-to-date with current technology. The mathematics is simplified wherever possible and copious references are given for further study and examples. The practising vertical transportation engineer involved with the sizing of a vertical transportation installation will find this an excellent and authoritative resource. Other members of the design teams: architects, developers and owners, will find the book a useful reference, and the needs of researchers, lecturers and students of the subject will also be satisfied by this simple presentation of the underlying theory. The engineering aspects, which fall into the areas of manufacturing and production, are not covered, but the practical constraints and considerations are indicated.

Book Description
A computer program (codenamed FOREL) has been written which simulates the lift traffic conditions existing in the morning up-peak and evening down-peak period for any specified single- zone office building. The program in its present form is a prototype for more sophisticated systems of lift analysis. On the basis of specified performance criteria, a number of feasible solutions are generated with a full listing of relevant information about each solution. To use the program the operator must supply the following data which is punched onto data cards: BUILDING LENGTH IN FEET; BUILDING WIDTH IN FEET; NUMBER OF FLOORS (ABOVE GROUND); STOREY HEIGHT IN FEET; HEIGHT OF GROUND FLOOR IN FEET; EXPECTED LIFE OF THE BUILDING. Internally are specified: a 5 minute handling capacity in terms of a % of building population (ie. 12%) a maximum value for the average waiting interval both of these figures are supplied for the morning peak period which is regarded as the critical period. On the basis of this information, the program then calculates the number of lifts of a certain size and speed which are required, checking each solution for the above criteria and against the performance during the evening peak period. Output from the program consists of a complete list of all possible, feasible solutions with the following information provided: NUM BER OF LIFT CARS; SIZ E OF LIFT CARS; SPEED OF LIFT CARS; AVERAGE WAITING INTERVAL, & HANDLING CAPACITY for morning and evening peak periods; RETURN TRIP TIME; AREA OCCUPIED BY LIFT WELLS EXPRESSED AS A % OF RENTABLE AREA; GRADE OF SERVICE ASSESSMENT; COST BASED UPON PRESENT WORTH SITUATION. This listing allows full comparison of all solutions. No final decision is made by the computer. The responsibility of this still rests with the designer. In this way, the program remains a design aid and not a design mechanism.

Book Description
Discover how to measure, control, model, and plan people flow within modern buildings with this one-stop resource from a leading professional People Flow in Buildings delivers a comprehensive and insightful description of people flow, analysis with software-based tools. The book offers readers an up-to-date overview of mathematical optimization methods used in control systems and transportation planning methods used to manage vertical and horizontal transportation. The text offers a starting point for selecting the optimal transportation equipment for new buildings and those being modernized. It provides insight into making passenger journeys pleasant and smooth, while providing readers with an examination of how modern trends in building usage, like increasingly tall buildings and COVID-19, effect people flow planning in buildings. People Flow in Buildings clearly defines the terms and symbols it includes and then moves on to deal with the measurement, control, modelling, and planning of people flow within buildings of all kinds. Each chapter contains an introduction describing its contents and the background of the subject. Included appendices describe measured passenger data and performed analyses. Readers will also benefit from the inclusion of: A thorough introduction to people-counting methods, including counting technology inside and outside buildings, passenger traffic components, and manual people-counting An examination of the passenger arrival process in building, including the Poisson arrival process and probability density function, and passenger arrivals in batches A consideration of daily vertical passenger traffic profiles, including two-way traffic profiles and the effects of inter-floor traffic An exploration of people flow solutions, including stairs, escalators, and elevators with collective and destination group control systems, as well as double-deck and multicar system People flow calculation and simulation models Elevator planning with ISO simulation method Elevator planning and evacuation of tall buildings Perfect for software designers in the private sector and academia, People Flow in Buildings will also earn a place in the libraries of elevator consultants, manufacturers, and architects who seek a one-stop reference for transportation devices from a functional and design perspective, as opposed to a hardware perspective.
