Traditional conveyance planning attacks fail to explicate and understand human demands for conveyance, since conveyance has direct effects on families and side effects on an person ‘s day-to-day activity agenda, every bit good as on the type and quality of activities. Ignoring this elements of human life, raises an pressing demand for research on human activities that might take to a better apprehension of conveyance and frailty versa its consequence on human activities.

So what is the option?

Transport is a derived demand which arises from people ‘s desire to take part in and out of place activities. By concentrating on activities, features and possible chances with regard to where and when the activities can be carried out, analyzed and better understood. Activity-based attacks in conveyance integrate cognition on the nature of activities, and their timing, with conveyance webs and their public presentation.

Then what is Activity based mold?

Activity based mold as a modelling attack does non hold a individual, incorporate theoretical base. It represents a aggregation of partial theories and a mixture of patterning attacks that portion the common subject of concentrating on activities engagement as the motivation force behind travel.

Activity based mold is a bottom up attack ; its unit of analysis is single ‘s behaviour and picks, at the micro or meso degree within the urban system. While the traditional four measure theoretical account ( trip based ) is a top down attack that focuses on geting a generalised behaviour and pick of group of persons ‘ based on figure of trips, trips origin and finish, and travel manner, doing it more macro degree in nature. Detailed temporal representations, timing and continuance of activities ( i.e. hours, weekdays ) are carried out in activity mold, while in trip based mold there are merely snap shootings or cross subdivisions of clip considered, e.g. top out hr traffic, or mean annual traffic etc. Similarly, the infinite or spacial facet of urban systems, is generalized and fixed in trip based theoretical accounts ( through TAZ zones centre, territories ) while, in activity based there is interaction of infinite clip, spacial topographic points at certain clip ( place, work edifice, shopping blocks ) .

Advantage of activity based aˆ¦aˆ¦aˆ¦aˆ¦aˆ¦aˆ¦

Although, this attack is significantly different from the traditional attack, still it is confronting batch of challenges, i.e. construing human behaviour right, covering with the complexness of urban environment, pull offing different and elaborate bed of informations acquired for patterning the trips ( population informations, day-to-day dairy of activities, etc. ) , the intersection between clip infinite of single utilizing different types of manners, to call merely a few.

Comparing the trip based theoretical account ( four measure theoretical account ) , with the activity based theoretical account, three chief characteristics are found to be of import for sing. These characteristics are single behaviour, clip allotment and infinite that activities are carried out within.

Individual behaviour and its ‘ consequence on metropolis construction, or metropolis construction and its consequence on single behaviour:

Planners are typically occupied with construing how urban development is impacting the morphology of urban environments, while bearing in head that there are of import spacial interactions impacting the relation between a human and his/her environing urban environment.

City or urban forms are the result of an interaction between motion engineering ( mobility, handiness ) , communicating and land values ( Venturi et al. 1972 cited in ) .Humans create metropoliss based on their activities, while metropoliss restrict our activities and behaviours within it. Similarly, Hillier & A ; Iida discussed the motive behind human motion ; antecedently research workers in cognitive surveies ( analyzing the procedure of perceptual experience ( believing, concluding, retrieving, conceive ofing or larning ) ) , believed that metric distance and cost are the chief explaining variables of human motion which was criticized subsequently as an unrealistic. Alternatively they proposed a new construct associating human perceptual experience of distance to the ocular geometrical and topological belongingss of webs, today known as infinite sentence structure. Consequently, they show that motion in metropoliss reflects the geometrical and morphological construction.

A symbiotic relation exists between conveyance and urban morphology ) .In order to obtain a proper apprehension of urban environment and it is quality, it is necessary to incorporate both aims ( landuse, edifice, street layout, population denseness, etc. ) and subjective ( single ‘s old experiences, day-to-day behaviour and life form, etc. ) in our rating of the urban system.In other words, sing “ the metropolis on Ground and the metropolis in Mind “ .

How to fall in both nonsubjective and subjective?

Dickenson, ( 1950, cited in, Pacione ) explained Urban morphology or town program analysis as “ advanced signifier of description and categorization of urban signifiers ” . While, Whitehand, ( 1991, cited in, Pacione ) described it as, analysing the insouciant forces behind urban land form alteration, Conzen in Pacione ( 2005 ) divided urban landscape into three chief elements ( town program ( street layout ) , constructing signifier and land usage ) .His categorization was based on the grade of alterations in these elements ; i.e. land usage is most susceptible to alter, edifices physically long-lasting while its usage might alterations over the clip, town program or street layout as the most lasting elements in the urban system, therefore street layout will be used in this survey as chief elements.

Continuing the treatment which started by, Penn argued the possibility to explicate people motion in infinite sentence structure, with the challenge to explicate why they move in this manner, by turn toing the inquiry: is it the motives or single knowledge? Cognitive infinite, is the infinite which supports our apprehension of the environing environment more extensively than our current ocular field, it is non a metric infinite, but it is about the relation and interrelatedness between urban elements.

To reply that, a new attack was developed to analyze the spacial description of urban construction in relationship to discernible behaviour, utilizing a non-metric infinite to pull out explorative motion from the metric visibleness graph, ensuing in the so called “ axial graph ” .

Axial graph is a set of lines which are called “ Axial lines ” . Axial lines, are the fewest and longest lines of sight that pass through every infinite consisting any system. or they are ‘lines of direct motion ‘or ‘ ocular measure ‘ in the 2D public urban infinite the agreement of this lines in infinite are called ‘axial map ‘ . .

This construct subsequently where used to pull mental maps ; a map which represents the cognition that a individual perceives from his environment. The intent of mental maps is to link the object ( street layout ) and the topic ( person ‘s old experiences, day-to-day behaviour and life form, etc. ) In other words, to be on the land while going in head around the metropolis.

Urban trips are clearly connected to single demands for travel ; microscopic or activity based mold of these trips can be achieved in three stairss:

Analyzing travel forms in the metropolis ; through making a scenario for each person, that describes the day-to-day trip of each person ( i.e. get down location of his trip, following halt location, clip continuance at each Michigans, location and clip of last halt and manner used ) .

Connecting different activities with physical construction of the metropolis ; through turn uping the twenty-four hours trips of persons into the physical signifier of the metropolis ; mentioning to the physical layout of the metropolis ( e.g. street layout, route web, axial lines ( ocular stairss ) , location and denseness of activities and temporal Michigans etc. ) .

Imitating the interaction between persons, with regard to clip and infinite ; through a dynamic simulation of each person ( micro simulation ) at each minute in his day-to-day trip from-to any location on the route web of the urban environment.

In short, the complexness of urban environment does non go forth topographic point for isolation. Achieving people satisfaction can merely be obtained by incorporating the societal with the physical portion of life. Using this attack in conveyance may make a new vision to work out current and future conveyance jobs.

Study Area:

The present survey will be conducted in Istanbul, Turkey. Istanbul is located in northwesterly portion of Turkey in the Marmara Region with a entire country of 5,343A square kilometres ( 2,063A sqA myocardial infarction ) . The Bosphorus, which connects the Sea of Marmara to the Black Sea, divides the metropolis into a tow parts ( European and Asiatic portion ) . Having its alone location, as the lone city in the universe that is situated in two continents, Istanbul is designated to be the alpha universe metropolis. With a population of 12.8 million, Istanbul is considered to be the largest metropolis in Meleagris gallopavo and the 5th largest metropolis in the universe ( Turkish Statistical Institute ) . That makes it the 2nd largest metropolitan country in Europe by population. Istanbul is megacity, every bit good as the cultural, fiscal, and economical centre of Meleagris gallopavo.

The transit system in Istanbul is confronting assorted jobs. As a Metropolitan metropolis Istanbul is enduring from route congestion, deficient capacity of route and public conveyance systems ( trams, light railroads and tubes ) , which is non plenty to provide public conveyance demand ( IMP sum-up, 2007 ) . However, presently conveyance policy in Istanbul in going more orientated towards sustainability giving precedence to better public conveyance and prosaic motion while cut downing conveyance cost, pollution, congestion and bettering vehicle substructure and sea conveyance.

Research job:

Conveyance planning has traditionally focused on calculating travel demand based on the well known deterministic four measure theoretical account which considers four chief facets of the day-to-day travel: figure of trips, trips origin and finish, travel manners and travel path as a generalised value for the population as a whole. While bearing in head the indispensable demand of persons to make a trip, where and when the activities can be carried out, how they may be scheduled, family ‘s features and possible chances, conveyance webs and assorted institutional restraints, such methods can be considered deficient to acquire a full apprehension of people ‘s travel behaviour without integrating some of these demands.

Urban planning and direction has focused mostly on the usage of societal, economic, cultural and governance factors in measuring urban alteration and development. GIS techniques have been applied to roll up, aggregate and analyse complex spacial informations that urban be aftering and direction demands. However, small accent is given to the elaborate signifier or geometry of the metropolis, and its consequence on mobility and frailty versa in these Fieldss. On the contrary within urban design there has been some focal point on geometry and signifier of metropoliss and human apprehension of the same e.g. through cognitive function. Small work has been done on associating urban signifier ( construction or morphology ) and the implicit in societal, economic, cultural and governance factors ( e.g. Chang et al. ) , allow entirely associating mobility.

This research will try to capture elaborate urban mobility forms for a sample of persons in relation to urban design rules through using a combination of different spacial and non-spatial techniques such as time-use study, street interviews, pulling mental guided by referenced maps. Better apprehension is sought by imitating these spiels in a dynamic simulation and statistical analysis of these single instances over the class of a twenty-four hours utilizing a multi agent conveyance demand simulation environment ( MATSim ) .

Why Activity based for patterning urban trips ( MATSim ) :

Due to the restriction of traditional four measure theoretical account and the new demand of conveyance mold that was mentioned above ; a new mold model is required. That should be capable of showing complex travel behaviour, explicating travel forms and calculating travel demand of persons.

MATSim as a conveyance simulation model is a flexible model, clip dependant and has a spacial declaration. which allows the integrating of different attack, developed by the user and supported by a big scope of inputs ( i.e. physical construction of route web, single travel form, manner pick, single property, etc. ) , every bit good a big scope of end product ( general statistic for the sample, elaborate statistic for persons, dynamic simulation ( film ) , geo referenced Google map simulation )

MATSim had proved in many surveies ( i.e. ( Balmer, et al. , 2006 ) ) that it is capableness to imitate persons ‘ day-to-day travel forms in different context. Equally good as, it could be a promising way toward the development of a following coevals of transit theoretical accounts, which could assist in back uping policy shaper in reacting to the current and future conveyance demands.

Research Objective and inquiries:

Main Aim:

To analyze the interrelatedness between urban geometry and activity forms of persons, concentrating on adult females, in the metropolis of Istanbul, Turkey.

Sub-Objectives:

The undermentioned sub-objectives are established to finish the model of this survey:

To develop a model and study instrument for day-to-day activity forms of adult females in Istanbul.

To put up and implement an activity-based theoretical account for patterning day-to-day activities of adult females in Istanbul.

To pattern and map the urban geometry of Istanbul, concentrating on showing urban street morphology.

To analyze the consequence of reinforced environment construction ( in footings of urban street morphology ) on urban mobility and activity forms.

To reason on obstructions that adult females face during their day-to-day trips.

Research inquiries:

The research inquiries are related to three chief sub-objectives:

To develop a model and study instrument for day-to-day activity forms of adult females in Istanbul.

How to follow adult females motion in the metropolis?

How locations and handiness of activities affect travel forms?

To put up and implement an activity-based theoretical account for patterning day-to-day activities of adult females in Istanbul.

How societal ( working, pupil ) , cultural discrepancies and urban construction affect activity forms?

To pattern and map the urban geometry of Istanbul, concentrating on showing urban street morphology.

How can urban form be defined and quantified?

What are the landmarks, nodes and their definition? How we can acknowledge each one of them ( in footings of Lynch ‘s typologies )

To analyze the consequence of reinforced environment construction ( in footings of urban street morphology ) on urban mobility and activity forms.

How does human activity and cultural facets affect urban construction in the metropolis?

To reason on obstructions that adult females face during their day-to-day trips

What are societal barriers that adult female face in their day-to-day trips?

How street web form motion in metropoliss?

What will be the consequence of rescheduling activities on travel form and engagement of single in out of place activities?

Research Hypotheses:

The purpose of this research is to prove the consequence of a metropolis ‘s physical construction on urban mobility. The research hypothesis is that adult females ‘s activity forms and agendas can be ( partially ) explained by urban morphological construction.

Methodology and Conceptual theoretical account:

Methodology:

The chief point to accomplish active and sustainable transit system is to incorporate all the elements that might be involved in fulfilling people demand.

This survey will be carried out in three chief stairss. A first measure in this attack would be analysing travel form in the metropolis ; by making a scenario for each person, through depicting his day-to-day trip:

start location of his trip,

following halt location,

clip continuance at each Michigans,

location and clip of last halt and,

Mode used.

This measure will carried out based on two attacks, foremost utilizing time-use study ( questionnaire ) , which contains inquiries refering:

Home based trips, intent of the trip, Activities ( location XY-coordinate, continuance clip, start clip, stop clip )

Persons socio -economic features:

Social statues ( employed, pupils, families ) ,

Income degree,

Marital position and gender.

Number of kids.

Mode used ( walking, cycling, private auto, public conveyance ) .

Conveyance webs ( walkers, cycling, private auto street and public conveyance path, Michigans and agenda ) .

The 2nd attack will be carried out based on Lynch in making mental maps ( inquiring person to pull their day-to-day trip through metropolis construction as seen by them depending on their ain cognition and background ) , so comparing these with a referenced map ( Google Earth or GIS map ) . Sketch map will be used.The intent behind Sketch map is to obtain rich cognition and information from the interviewed individual, without seting any restraint to his thought, while utilizing a referenced map, give us realistic information about the paths persons follow with less item so aˆ¦ . p.485.

By researching the metropolis physical construction Lynch ( 1960 ) identified five major elements of urban construction which are identified by the single dwellers. These characteristics are:

Landmarks ( fixed and identifiable objects which give a sense of the topographic point and can be referenced from exterior ) ,

Districts ( Sections of the metropolis cloth that have an single fibre which provides coherency, leting the full to be viewed as a individual unit ) ,

Waies ( channels of travel through the environment such as major roads or pathwaies ) ,

Nodes ( Important points of involvement along certain waies, e.g. route articulations or town place besides been described as the topographic point where people had to take a determination ) ,

Edges ( additive elements supplying boundaries to territories or additive obstructions ) .

These elements are descriptive in footings of urban spacial agreement by placing these elements and its elaborate property. It is possible to modify local relationships, between the physical elements itself, and the societal economical factors, surround it.

However, we must be cognizant of the fact that different societal groups have different reading of the same topographic point, which happens due to two chief ground ; the difference of the environment experienced and aims by the two different groups.

To analyze the consequence of reinforced environment construction ( in footings of urban street morphology ) on urban mobility and activity forms.

By linking activity that persons do over the class of twenty-four hours, with physical construction of the metropolis ( Landmarks, Paths and Nodes ) :

Activities ( locations X, Y )

Road web ( links id, from node, to node, capacity, velocity, figure of lanes )

axial lines for walkers, bicycler and private autos ( Hillier, et al. , 2005 ; Long, et al. , 2007 )

Public conveyance paths, Michigans XY.

Using person ‘s programs ( descriptive signifier ) extracted from old attacks ( inquirer, mental map and referenced map ) , while change overing those programs to Digital signifier in GIS, Excel and Google Earth.

To imitate activity forms in the metropolis, integrating of the end product from the last measure into MATSim must be carried out. Where the digital signifier of Road web, person ‘s activity programs, activities location will be converted to xml format.

Execution of the activity, in regard with clip and infinite will be started up through a dynamic simulation of each single activity over the class of a twenty-four hours.

End product:

Using MATSim to imitate this interacting, three signifiers of end product are obtained.

First, an overall statistical for the activities carried out around the metropolis as graph, combined with single graphs show persons motion cross a certain section of the route in relation with certain section of clip,

Second, film demoing single interaction,

Third, a Google Earth simulation.

Finally, uniting the three signifiers of end product in the analysis, we hope to acquire replies for the research inquiries, which might assist policy shaper to acquire an reply to the current and future adult females ‘s conveyance demands.
