Abstract

Highlights

 In this study, after recognizing the principles of infill development and determining the indicators related to these principles in the form of research analysis model and localizing them according to the conditions of our urban contexts, to recognize these indicators in District 1 of Tehran Municipality as a case study. The research was conducted and then the camera was installed in three desired areas using the behavioral pattern analysis technique. With the indicators and their overlap, we reached a single result, which represents the proposals with the highest potential for infill development in the range.

Then, after recognizing the principles of mesenteric development and determining the indicators related to these principles, solutions were proposed to improve the study area. With field studies, interviews and questionnaires, and with the method of behavioral pattern analysis and using detailed area plan maps for each group of solutions, the following suggestions were presented; How to achieve the following suggestions is on the one hand the result of analyzing the information of step 4 of the behavioral patterns method and on the other hand, the result of field interviews at the site and interviews with experts.

Urban landscape quality improvement strategies:

1.  Enhance readability by using existing elements and signs such as Imamzadeh Saleh;

2.  Increasing the visibility of urban signs and symbols;

3.  Use of monuments and urban landmarks as routing systems;

4.  Creating a defined and continuous perspective and not interrupting it with pedestrian overpasses.

5.  Conversion of waterways leading to fresh corridors with mixed uses in Maghsoudbek River Vally;

6.  Creating a suitable landscape from inside to the Alborz mountain range;

راهکارهای ارتقای رونق اقتصادی و بهبود دسترسی ها:

Urban landscape quality improvement strategies:

1. Providing standard urban per capita to achieve appropriate urban services using barren, abandoned land and dilapidated contexts;

2.  Using mixed uses to attract collective activities;

3.  Maintaining and strengthening the axes, activity centers and active and lively nodes;

4.  Creating opportunities for 24-hour activities in the area of Quds Square to Tajrish;

5.  Increasing the permeability of passages in the context for critical situations;

6.  Use of vacant lands to create active land uses and organize street markets

Strategies for promoting cultural aspects:

1.  Creating educational, cultural and sports environments

2.  Preservation and promotion of collective memories and identity through historical monuments around the area. Like the mourning of Muharram in the Takiyeh of Tajrish;

3.  Creating opportunities to create a display of local identity and history through the functional and conceptual implementation of popular design and presentation

4. Establishment of training classes by increasing health, social and welfare support, which will lead to their greater participation in the implementation of urban service projects;

5.  Creating the necessary space for the activities of various social groups such as children, women and adults;

6.  Creating the necessary facilities for weak groups such as the disabled and the blind in space;

Solution to create safe spaces:

1.  Control of new physical constructions to coordinate with the texture;

2.  Proper and coordinated flooring for the integrity of the space;

3. The use of urban furniture appropriate to the space on pedestrian axes;

4.  Adaptation of the environment and definition of the pedestrian network between urban and market signs;

5.  Establishment of pedestrian and bicycle paths around the river and along the main thoroughfares;

6.  Strengthening the connection between the two banks of the river by pedestrian bridges;

7.  Calming the streets leading to crowded spaces;

8.  Expand public transportation and encourage people to use it;

9.  Creating public parking lots around the area and reducing marginal parking in the area;

10.  Elimination of unsafe spaces in the area of worn context behind Tajrish Bazaar by using design actions;

11.  Visibility of spaces by creating visual clarity and proper lighting

Solutions to pay attention to environmental issues:

1. Predicting the protection of the natural cycle of the river; Ecological protection of water and the surrounding area;

2.  Necessary measures to reduce environmental pollution, such as organizing the sewage system and disposal of surface water and directing it before entering the river;

3.  Proper use of existing topography to create spaces with a population-absorbing landscape;

4.  Use of covered streams and street gutters to repel surface water and reduce environmental pollution;

Land is the most important factor in development and how to use it is one of the most important issues in urban planning. Population growth and urban development have put increasing pressure on urban land, resulting in the destruction of land around cities.

 Scattered urban development and land use change around cities have been major challenges in urban planning and design in recent decades. Infill development policy has comparative advantages over other urban development policies due to lower costs of preparation, maintenance, security, law enforcement, and easier access to municipal services.

The infill development model is a good tool for attracting population overflow to wisely manage space in land use, reduce land prices by extracting worn-out land instead of the cost of preparing wasteland, and expand cities vertically by renovating and rehabilitating old urban structures. And avoid destroying gardens or expanding the city limits.

In this study, after fully identifying the study area and the principles of infill development and using behavioral pattern analysis technique, indicators related to infill development, which include attention to environmental issues, cultural and recreational spaces, urban landscape promotion, create safe places, spatial rehabilitation, access improvements, economic prosperity, increased permeability and user mixing were extracted.

 With field studies, interviews and questionnaires, and with the behavioral pattern analysis method, and using the detailed area plan for each group of indicators, suggestions were made on how to obtain the suggestions from one side of the data analysis step 4 of the behavioral pattern method and on the other hand, the result of field interviews on the site and interviews with experts.

One of the proposed solutions to improve the study area: increase security in the direction of Maghsoud Beyk river valley; Provide the necessary facilities for disabled groups such as the disabled and the blind in space; Ecological protection of water and the surrounding area, elimination of unsafe spaces in the area of worn texture behind Tajrish Bazaar by using design measures, calming the streets leading to crowded spaces, etc. can be mentioned.
