Smart Cities has a wide range of definitions across the industry with lots of promises being made on technology that can achieve ambitious outcomes. At SAGE we have a simple and concise vision on what Smart Cities is:
Smart Cities is the optimisation of city resource allocation through data, which allows reactive processes to become predictive.
But what does this mean in practice and how do we achieve this predictive nirvana? Most organisations undergo this transformation in three stages:
In this stage, there are often personnel or equipment on standby, waiting to respond to an incident or situation. This stage also represents a planning approach where far more facilities are built than required because there is uncertainty around the actual number of visitors in an area.
Waste management – Bins are emptied on a schedule whether they are full and overflowing, or empty.
Urban planning – A new area is built with excess spare car parks, seats or bathrooms because it is not known how many people visit the area.
Irrigation – An oval is watered on a fixed schedule, regardless of the environmental conditions.
Transport – The road network is planned using historical road counts taken over one day from the last 10 years and delays are expected when travelling from one place to another.
In this stage there is a reduction in faults, congestion and delays. Resources are more efficiently allocated, meaning that there are lower capital costs in planning and less ongoing expenditure for maintenance and support.
Waste management – Bins are emptied when they reach a threshold level or the appropriate schedule is calculated based on historical trends.
Urban planning – Pedestrian movement counts indicate that there are 150 visitors per hour and they stay for an average of 45 minutes, requiring two sets of amenities. Car parks in surrounding areas are measured to be underutilised so a reduced number of new car parks are required, resulting in more space for public art.
Irrigation – The oval is watered when the soil moisture is low or when measured enviro-transpiration indicates that the ground is dry. This results in reduced water usage and better environmental outcomes.
Transport – Real-time congestion is known and delays can be managed. The road network can be planned around the management of peak periods which consider time of day, special events and school periods.
This is an ideal state which organisations should strive to achieve. This stage will draw upon historical data, the current state of the system and use this to guide a course of action which achieves the task at the correct time.
Waste management – Bins are emptied as they become full, the collection route is optimised to ensure the shortest route is taken to empty the fullest bins. Public events are anticipated and bins are emptied prior to surge periods.
Urban planning – The number of pedestrians is projected into the future based on accurate historical trends and rates of growth. Parking locations are dynamically made available as required, allowing shared use areas for pedestrians only when parking demand is low.
Irrigation – The oval is watered in anticipation of a hot day during a time when the wind is low. The appropriate amount of water is used to suit the soil, grass type and foot traffic.
The challenge of meeting the predictive state seems daunting, but through a process of gathering applicable data and integration of business rules, the optimal state can be practically achieved. Here are some practical ways to move towards an optimised state:
It might be difficult to see your city truly reaching the fully optimised state, but it is possible. Through a smart approach with the support of data, the practical steps to eliminating waste will result in a measurably better use of resources.
SAGE can help with all stages of this transition, from collecting and aggregating data to implementing useful business rules. Any improvement in how resources are allocated is undoubtedly linked to an increase in community liveability.
