1- Introduction1- Introduction

The rise of sustainable transportation (ST), as an integral part of the sustainable development movement.

1-1 Motivation: Why Sustainable Transportation? Why Sustainable Transportation?








Growing unsustainable transportation trends (dominance of car-based and mono-driving movement).

Transportation..energy consumption..pollution


1-1 Motivation: Why Sustainable Transportation? Why Sustainable Transportation?








Responsible bodies are promoted to take appropriate actions and opening the door on ST in a broader context.

The concept is no longer conceptual; efforts are initiated: i.e. drafts, guiding principles, checklists, rating systems and assessment methods.

Efforts vary in nature, scope and influence due to the varying conditions between and within countries; diversifying the way ST can be achieved.


1-1 Motivation: Why Gharb El-Balad District? Why Gharb El-Balad District?








The historical, social and cultural values as the nucleus of Assiut City and one of its ancient parts.










Recent developments were oriented toward newer districts, while the GEBD lacked awareness.

The district is overpopulated and overcrowded, being marked by the shortage in major services and facilities.










Despite the deteriorated profile of the

GEBD, its compact

urban form, well inter-connected

street network and the

adjacency to Assiut City

future extensions

represented positive

indicators.


The aim was to explore the potential of ST to develop the GEBD street network; giving it the chance to experience a level of sustainability in relation to transportation.

1-2 Aim and Objectives: What does the paper aim? What does the paper aim?








Investigating the complexity of ST; deriving its key-attributes.

Identifying the strategic directions to ST. Studying the possibility to apply these directions to

the case study.

For the aim to be attained the following objectives were to be accomplished:


To achieve the stated objectives,

a seven-step research

methodology was proposed.

2-1 Definitions and Guiding Principles: dology: Theoretical Background Theoretical Background








The 1987 report of the World Commission on Environment and Development.

The literal economist’s, environmental and comprehensive definitions of the OECD.

The 9 guiding principles proposed by Canada's National Round Table on the Environment and the Economy (NRTEE) in the OECD Conference in Vancouver. ('Towards Sustainable Transportation', 1996).

The OECD 4 scenarios to achieve sustainable transportation for 2030.

2-2 Checklists and Rating systems : dology: A Step Towards Application A Step Towards Application








Sustainable Transport Masterplanning Checklist (2008); 8 key issues to achieve sustainable transportation.

The pilot version of the LEED rating system for Neighborhood Development (LEED-ND): assigning a full Credit for 'Alternative Transportation'.

The LEED rating system for New Constructions (LEED-NC); assigning two groups of credits to support sustainability in relation to transportation: 'Smart Location and Linkage' and 'Neighborhood Pattern and Design'.

3-1 Key-Attributes: Investigating the Complexity and Richness of ST Investigating the Complexity and Richness of ST








27 ST attributes were derived, put under one roof, analyzed

and categorized to

fall into 11 interrelated

groups;11

key-attributes


3-2 Interrelationships of ST Attributes: In-Depth Analysis In-Depth Analysis








Seven types of

relationships among the attributes assigned

values from +4 to -3;

referring to the strength and type of

the relationship.

6- Conclusion Of the Work Correlation Values of ST Attributes


3-3 Strategic Directions to ST: How to do it? How to do it?








24 strategic directions are proposed to achieve the

11 key attributes of

ST.

Each direction seems to

support more than one

single key-attribute.

4-1 Urban Analysis: Image, Land-use, Heights, Cases, Spaces & Street Network Image, Land-use, Heights, Cases, Spaces & Street Network








• Compact urban form.• Well inter-connected street network.• High percentage of public spaces (26% mostly

streets).• Over-populated and over-crowded context.• Mixed land use and dominance of commercial

activities.• Shortage in services and facilities.• High percentage of deteriorated buildings (28%).


4-2 Street Network: SWOT Analysis SWOT Analysis








Strengths Weaknesses Legible mental image. Compact urban form and permeable street

network support inter-connectivity. Main streets are well paved, and the

infrastructure is installed. High percentage of public spaces (26%). The main arterial road, of 15m width,

supports public transportation. Private cars ownership is at minimal rates

(0.006 private car/capita) when compared with the national average rate of 0.023%.

Low income rates do not allow people to own private cars, encouraging walking, cycling and public transportation.

Widths of street network do not enable safe walkways and cycling routs.

Car movement takes the priority over walking and cycling.

No public transportation (dependence on taxis)

No central parking areas. Lack of services and facilities. Lack of vegetation. Due to high illiteracy rate, the issue of

sharing the environmental responsibility and raising public awareness can be considered academic.

High rates of emissions due to deteriorated car engines owned by residents.

Opportunities Threats The district is attached to future land

extensions; therefore, these extensions can be accessed through the GEBD.

Low degree of governmental awareness. Absence of NGOs and public participation. Lack of funding resources.

5- Discussion: Results and Research Attainments5- Discussion: Results and Research Attainments








1. In this paper, it was argued that there would be no single best way to achieve ST due to the varying conditions (adopting the concept of 'think globally and act locally‘).

2. The paper managed to induce a taxonomy of ST attributes, as they were derived from the literature, to fall into 11 key-attributes.

3. The paper argued that achieving one attribute of ST would influence and be influenced by achieving other attributes.

4. The in-depth analysis showed ST attributes to have various relative weights due to the various correlation values (from +78 to -21) they have.

5- Discussion: Results and Research Attainments5- Discussion: Results and Research Attainments








5. The analysis showed that more dependence on public transportation together with the restricted car movement can be considered the most influential strategic direction to support achieving ST.

6. On the contrary, the excessive parking areas is to maximize transportation demand; negatively influencing the achievement of ST.

7. The paper managed to issue 24 strategic directions to achieve ST.

8. After analyzing the GBED profile, strategic directions to ST were integrated with the local context providing the research with a solid ground on which appropriate actions were proposed and a strategic plan was developed.

6- Conclusion:6- Conclusion:








In this paper, the GEBD was given the opportunity to experience a level of sustainability in transportation, based on an overall urban analysis as well as a SWOT analysis of its street network.

ST theoretical perspectives and guiding principles were closely integrated together with the pressing local context of the GEBD.

As a result, a development strategic plan was proposed based on studying the application possibilities of 24 ST strategic directions.

In conclusion, the research appeared to bridge the gap between theory and practice in terms of investigating the potentials of ST as a theoretical issue, to develop an existing district with a relatively pressing local profile.
