The Benefits of GIS in ADEC (ROI Perspective)
Pakrad Sarkis BalabanianEIS Team LeaderAbu Dhabi Education Council
About ADEC• Abu Dhabi Education Council (ADEC) was established in
2005 in accordance with the vision of His Highness Sheikh Khalifa Bin Zayed Al-Nahyan, the UAE President, the Supreme Commander of the Armed Forces and the Ruler of Abu Dhabi to provide all students in the Emirate of Abu Dhabi with access to quality education
• ADEC has developed a 10-year Strategic Plan to drive improvement in the P-12 sector and deliver education of the highest international standards The Strategic Plan has identified different priorities for its Vision and Mission:
– Elevate Schools Quality in Abu Dhabi to International Standards– Improve Access to P-12 Education– Provide Students with Affordable Options of High Quality Private Education– Help Learners to Contribute Positively to Society– Build ADEC Capabilities– Enhance Stakeholder Engagement

GIS Applications
• GIS technology has been instrumental in achieving the goals set out by ADEC
• GIS can be used bydifferent departmentsIn ADEC in addition to educational zones,school administrationsteachers, studentsand parents…
GIS ROI
• For many years IT projects have been initiated largely based on qualitative, value-added reasoning.
• To be successful, IT strategies must be aligned with business strategies, and IT processes must reflect business processes.
• ROI studies use a combination of qualitative and quantitative measures to assess the utility that an organization will obtain from an investment.
• Benefits can be categorized as Tangible and Intangible GIS benefits
Transportation ManagementPilot Project
• Abdullah Bin Otaibah School was selected to do the pilot project
• All bus trips were surveyed with GPS• esri® ArcLogistics™ & ArcMap™ were used to
calculate different scenarios of optimization• A comparison between The current situation, and
other optimized scenarios represents the benefits of using GIS…

Potentials & Targets
• If 1Km is reduced per bus on average:
• The U.S. Environmental Protection Agency (EPA) classifies diesel emissions as a "likely carcinogen." Diesel emissions are estimated to be responsible for 70 percent of the cancer risk arising from air pollution.
• According to the California Air Resources Board. Dangers from diesel exhaust can range from respiratory illnesses including asthma and bronchitis to lung cancer and heart disease.
• Children are more vulnerable to the effects of diesel exhaust than adults because they breathe more quickly and take more air into their developing lungs. And on average, school children who ride the bus spend an average of 90 minutes each weekday in transit
Total Distance Saved Per Year 495,000 KM
Emission: Hydrocarbons 1,080 KG
Emission: Carbon Monoxide 8,520 KG
Emission: Oxides of Nitrogen 557 KG
Emission: Carbon Dioxide2 160,443 KG
Potentials & Targets
• If number of buses were reduced by 5%:– Cost Saving will be ≈ 10,725,000 AED
2,979,167 USD
• If number of buses were reduced by 10%:– Cost Saving will be ≈ 21,450,000 AED
5,958,333 USD
Other Benefits
• Reducing student commuting time• Tool for assessing the current situation• Tool for assessing the contract with the
transportation company• Tool for KPI measuring• Helps Decision Makers to forecast the impact
of their policies and decisions• Cost Savings• Reducing traffic jams and pollution
