We live in a fast-paced world where people are frantically juggling their professional and personal lives. With advances in science and technology, the transportation and communication sectors have advanced significantly, reducing the amount of time, resources, and effort expended in travel. Electric vehicles have evolved over time, with the assistance of artificial intelligence and quantum computing, to become highly efficient and optimized for people’s transportation.

Quantum computing has a variety of applications in revolutionizing the automobile industry such as improving battery performance, avoiding traffic congestions, preventing car accidents and mishaps by machine learning and analysis etc. that can greatly benefit the sector when they come to fruition. Machines in quantum computing work with physical properties of matter, such as superposition or entanglement, which means that calculations can be performed on multiple states of matter at the same time, drastically reducing computation time.

Advantage of Quantum Computing The brainchild of Nobel laureate Dr Richard Feynman, quantum computing has progressed to enormous levels of growth, finding a variety of applications in different fields and sectors. Quantum computing involves simulation of the physical nature of objects at subatomic sizes while allowing them to exist in more than one state. This allows rapid simulation and processing of data than conventional systems, making quantum computers much more powerful, efficient, and faster. It has been applied in fields like Cryptography, Medicine, and material sciences to accommodate multiple variables or molecules in simulations to reach the desired end product or solution. Various automobile companies like BMW (CNET) and Hyundai (Eetasia) have started working with quantum computing systems to solve various issues like cost optimization, development of new batteries, optimization of components to improve cost-effectiveness etc.

Quantum Computing in Battery Technology

Quantum computing has been applied to develop effective solutions in improving the battery technology in cars and automobile systems as it can simulate multiple molecules of compounds simultaneously in different states, conditions, and environments to help identify the ideal combination of variables. Hyundai Motor Co. has partnered up with quantum computing experts to develop a robust battery that can function with improved capabilities and durability when used in electric vehicles. They aim at reducing the cost of battery development and production to reduce the overall cost of the vehicles, improve affordability and progress towards sustainability. A quantum computer of sufficient complexity—for example, enough quantum bits or “qubits”—could theoretically achieve a quantum advantage, allowing it to solve problems that no classical computer could ever solve. In theory, a quantum computer with 300 qubits fully dedicated to computation could perform more calculations in an instant than the visible universe’s atoms Quantum computing has also been applied in the development of novel technologies that can improvise the functioning of EV batteries by incorporating advanced technologies to cool them. It is applied by compartmentalizing big issues into individual parameters that are simulated using quantum computing to be later integrated into the conventional systems as a hybrid model or to fashion a completely new model by combining the solutions offered by quantum computing(EENewsEurope).

Quantum Computing in Autonomous Driving Quantum computing can facilitate the design and development of powerful operating systems to produce self-driving cars, simplifying transportation and reducing the chances of human errors in road traffic accidents. Artificial intelligence and machine learning require the real-time analysis of vast amounts of data to produce optimal responses to changing environmental conditions and quantum computing with its excellent computational features

can lend a hand in facilitating the requirements. Volkswagen(Prescouter) has experimented in the design and development of computational systems to optimize traffic control and regulation in the city of Beijing and has found great success in this venture. It also has applications in improving vehicle to vehicle and vehicle to cloud communications in next-generation cars that are expected to have the ability to communicate with cloud computing systems to regulate driving data. This will help in traffic and fuel optimization in cloud-connected cars while providing a safe environment for decentralized communication between them.

Conclusion

Quantum computing has unlimited potential and practical applications across different fields and sectors and can make a path for enormous progress in the automobile sector. Companies and enterprises in the automobile sectors would greatly benefit by working with quantum computing as it is a leap towards greater sales and a greener environment. Recently, quantum computing has gained a lot of traction in both general society and the private sector. Companies have been pouring huge sums of money into quantum computing research, with the last few years being the busiest for this innovation.

Designing Micro-Transit Ride Matching and Relay Algorithm https://experionglobal.com/designing-micro-transit-ride-matching-and-relay-algorithm/ https://experionglobal.com/designing-micro-transit-ride-matching-and-relay-algorithm/#respond Mon, 20 Jul 2020 05:42:17 +0000 https://www.experionglobal.com/?p=6089 Transportation enterprises are constantly looking for methods to increase operational efficiency. The focus is always on reducing the time required for a passenger (demand) to get the cab (supply) as well as for the cab drivers (supply) to engage in the next ride request (demand). This blog illustrates how to choose the best ride-matching and relay algorithm for a micro-transit service provider.

According to SAE International, Microtransit is defined as a privately or publicly operated, technology-enabled transit service that typically uses multi-passenger or pooled shuttles or vans to provide on-demand or fixed-schedule services with either dynamic or fixed routing. 

Micro-transit offers superior customer experience and improved efficiency of services with real-time supply and demand, dynamic pricing, tracking, cashless payments, customized seat location, and so on. This drives numerous transit agencies to offer micro-transit services in different capacities. Micro-transit transportation could be an alternative to otherwise public transport commuters, and the trend is likely to rise going forward. 

Customer retention is high as long as the providers can ensure a seamless experience, which can be assured by the IT experts that provide software solutions to these companies. Leveraging solutions providers’ technology expertise, micro-transit companies can meet changing market requirements of shared urban mobility sustainably.  

How we developed an on-demand micro-transit product empowered with a scalable, high-performance ride-matching and relay algorithm

Transportation enterprises providing on-demand taxi services constantly look for methods to increase operational efficiency by reducing the time required for a passenger (demand) to get the cab (supply) as well as for the cab drivers (supply) to engage in the next ride request (demand). 

The main component of such an on-demand micro-transit solution is the Ride matching and relay algorithm, which identifies the cab for a specific ride request.

Objectives / Design considerations for the algorithm:

  • The application should respond to ride requests in real-time to ensure that passenger spends minimal time on ride searches.
  • It should handle the unpredictable peak-request-load for ride requests. The algorithm should auto-scale to handle all the requests and still provide the same performance as regular non-peak hours.
  • The algorithm functions based on multiple configurable parameters like geospatial proximity, dry run distance, provision for a uniform opportunity, ride request rejections, average KPI ratings of drivers and passenger, variable pricing strategies, live location of a cab, etc.
  • It should be able to integrate with online navigation services which consider congestion data. The algorithm should execute geospatial queries for the real-time calculations involving driver-vehicle location data.
  • The algorithm should ensure that service is available 24*7 

Why did we choose AWS Lambda with Python?

The application should be designed to handle a large number of concurrent ride requests during peak times without impacting its performance. With limited time to market, we started exploring cloud-based services that could work as a platform for the algorithm to run. 

AWS Lambda was known to be highly scalable and could process high loads. Lambda has a serverless architecture, which means that you do not have to keep an instance of the server running at all times. The product was being developed in .NET for APIs, and since AWS Lambda supported .NET, it was the natural first choice.

We completed a proof of concept using AWS Lambda with .NET functions. However, during the proof of concept phase, it was found that there was a weakness in Lambda named ‘Cold Start’. We had to find a solution to manage cold starts. 

What is a Cold Start?

Cold Start is the ‘start-up’ time required to get a serverless application’s environment running when it is initiated after a period of inactivity. Lambda applications run on ephemeral containers managed by AWS. AWS has its own complex algorithms to manage the infrastructure dynamically based on what we have subscribed to in the Lambda configuration. If Lambda services are not being invoked for a while, the containers managed by AWS Lambda shall shut down to save its valuable computational and memory resources. When the Lambda service is triggered again, resources must be allocated to it again, which results in latency. 

When we tried the proof of concept with AWS Lambda services written in .NET, we noticed that the cold start time was in the range of 5-10 seconds. Our business APIs were written in .NET. GIS-based APIs were written in Python as it had excellent libraries to handle geospatial functions and data volume. Since AWS Lambda supported Python, we decided to try Lambda services written in Python.

Cold start for AWS Lambda with Python was noticed to be less than half a second, and hence we narrowed down on using AWS Lambda with Python services.

Designing the ride-matching and relay algorithm 

Having settled on the technology to be used, we designed the Ride Matching and Relay Algorithm as follows:

  • We decided to use DynamoDB in AWS to store and manage the ride requests. DynamoDB had very good read or write response times and is known for its performance along with the ability to auto-scale. The ride requests from passengers were written into an AWS DynamoDB table. Multiple ride requests may be raised concurrently by different passenger.
  • Ride matching and relay algorithm picks up the ride requests from the DynamoDB for processing.
  • The algorithm is designed with a three-level hierarchy of Lambdas to separate layers of responsibility to optimize the execution time.  Each layer processes information and returns the result to the parent Lambda function:
    • Level 1 Lambda – This Lambda service sits at the highest level. It reads the DynamoDB table for new ride requests at regular intervals. It groups a set of ride requests and spawns level 2 Lambda services. 
    • Level 2 Lambda – This Lambda service gets a set of ride requests as input. Its main function is to further spawn multiple Level 3 Lambda services for each ride request, accept the selected cab driver for the ride request, and write this into the DynamoDB for a ride request.
    • Level 3 Lambda – This Lambda service gets a specific ride request ID as the input. The objective of this Lambda function is to identify the cabs that qualify for the ride request, score them, and find the highest-ranked cab to serve the ride request. This scoring is based on multiple parameters like distance, time, driver KPIs and many more.
  • Based on the cab driver allocated against a ride request, the algorithm will invoke another Lambda service to send the ride request to the driver’s mobile app. 
  • In case the driver rejects or misses the ride request, the ride request is passed to the algorithm again.
  • If the algorithm is not able to find any supply for the ride request after X seconds another Lambda service will remove all the expired requests.

Achieving the desired output &  delighted customers

The application was developed and deployed into production and met all client expectations and market requirements, which in turn resulted in happy customers. Customers are able to find rides using the application with minimum waiting times, thanks to the ride relay algorithm. The response time of the algorithm was consistent across different loads. There were even scenarios where the peak volume of ride requests went much above the expected levels. No deterioration in performance was noticed and the system was able to cope up with the unanticipated levels of load.  

In conclusion

Our ability to reap the benefits of on-demand micro-transit transit services will depend on companies’ creating superior products that support and meet dynamic market conditions. We at Experion are proud to have developed and delivered a micro-transit on-demand product with high potential for innovation and scalability, reduced costs, ensuring tangible benefits for our client.

The speed and extent of mobility transformation today is vastly different from what we have seen in the past. With an increasing number of megacities growing around the world, mobility for all those within it becomes a challenge.  Well-planned urban mobility strategies backed by sufficient investments are needed to solve the transportation challenges the masses will face, and no doubt already do. 

With high internet penetration and access to smartphones, on-demand services have opened up a new arena of services to customers by offering consumers what they want, when they want, without owning a car. Commuters find it easy and convenient to just have to open their smartphones to find and connect with various transportation modes available for a ride. 

According to McKinsey, 23% of Americans have no interest in owning a car, proving the changing mentality and openness towards adopting on-demand ride hiring services. The global on-demand transportation market size is expected to reach USD 304.97 billion by 2025, with innovative mobility solutions and the rising adoption of connected vehicles. 

Building a ride-hailing application – The challenges & the way-around

Experion was approached by a leading transportation provider in the Middle-East to develop an on-demand ride-hailing application after they realized the vast market potential and opportunity it held. Designing and developing such a responsive, scalable application with a real-time communication engine requires significant architectural foresight, and in this article,  we will delve into how the team at Experion designed and built the real-time communication module in this product. 

The heart of any ride-hailing application is the real-time communication system between the driver application, passenger mobile application, and the backend APIs. This real-time communication framework ensures the flow of events through the complete ride life-cycle (from ride-booking until ride completion). A product of this nature has to be high performance with expected response times in milliseconds, and communication (ride status, driver status, locations, etc.) has to flow between the mobile apps, web, and API seamlessly. The real-time communication module has to be scalable in nature since peak-time cannot be predicted. Back-end APIs use the real-time data from mobile as input to its sophisticated routing and matching algorithms that manage supply and demand matching. Based on real-time communication, notifications were to be sent to various client applications (drivers and passengers) through notification services. 

This solution suite needed to be developed in a short time period of a few weeks, due to the critical launch-date provided. Timelines for development, scalability of the solution, and the performance expectations of the real-time communication engine were all of equal importance as we started the architectural considerations process.    

Real-time communication solution options and decisions:

The main decision factors that we had to consider during this process were:

  • Highly responsive framework with the entire publish-subscribe cycle working within milliseconds.
  • Minimum learning curve and development time
  • Availability of APIs (SDKs) which can be accessed from native Android applications, native iOS applications, REST APIs, and AWS Lambda programs. 
  • Scalability during peak time – Preferably cloud-based solutions with automatic scaling options. 
  • Offline support for mobile applications that work regardless of network latency or internet connectivity.
  • Preference for an AWS based service, since the rest of the solution, was in AWS stack.

An illustration of the expectation from the real-time communication framework is given here:

  • Locations of all logged-in drivers and pax are to be tracked in real-time. If mobile devices lose internet connectivity/involve slow networks, the real-time communication framework should manage the synchronization and communication with the server.
  • Every driver who is ready to accept a ride will be available in the real-time communication data store and shall be available for the ride-matching algorithm to pick. 
  • When a ride request from a pax is initiated from the mobile app, the real-time engine should notify the AWS Lambda Ride Relay algorithm with details of the ride request. 
  • Once the Ride Relay Algorithm selects a driver, the real-time communication framework should immediately show the ride request in the driver mobile app. 
  • If the driver accepts the ride, the real-time communication framework should send the driver’s data to the pax app along with the driver’s location and contact details. 
  • The driver’s movement will be updated into the real-time communication framework from the driver’s mobile application and it will be displayed in real-time in the passenger’s mobile application. 

This illustration is just shown as an example of how a real-time communication network should function. The actual product has many more sophisticated real-time communication scenarios that have to be managed by the selected communication framework. 

Based on the requirements made evident from the illustration above, the following technology options were considered:

Option 1: Socket Based Communication

Socket-based communication was not favorable due to the relatively large learning curve needed to develop a socket-based communication framework from scratch,  and a longer development schedule while using it. Developing such a communication framework with an entire real-time event management framework with subscribe-publish model interfacing with the mobile, web, and API side in a short time could result in product quality issues. It was too much of a risk, and hence we rejected this option.

Option 2: AWS Appsync

The client wanted the product to be deployed in the AWS infrastructure. Technology choice for the scalable, high-performance demand-to-supply matching, and relay algorithm was AWS Lambda. Though we thought about creating a framework with SQS, SNS, and our own custom API code, the architectural considerations for automatic handling of mobile app connectivity issues made us think about other options. AWS Appsync and Firebase were the options that could satisfy most of our requirements.

We decided to explore AWS Appsync as the real-time communication framework.  AWS AppSync could be used in conjunction with DynamoDB (which is a high-performance data store for AWS), both of which had seamless integration capabilities with Lambda functions. In addition, we believed we could take advantage of having everything in the same AWS services framework.  

We created a feasibility checklist to verify the important capabilities expected from the real-time framework and quickly executed a proof of concept exercise for AWS Appsync. Based on this, AWS Appsync ticked against most of the points, and it integrated well with the rest of our architecture. We finalized on using AWS Appsync for real-time communication and started the development with this. As per our design, we were using multiple Appsync data stores/nodes for ‘Ride Requests’, ‘Driver-Vehicle Pairs’ etc. to dynamically handle real-time communication. AWS Appsync was working well during our development and unit testing phases. 

However, towards the closure of the development stage, when we started the integration tests simulating real-life peak scenarios, we started noticing some inconsistencies in the communication. When many concurrent requests were being served, it was noticed that the ride status updates like drivers accepting a ride or canceling a ride, etc. were not updated properly through AppSync (in DynamoDB) for around 20% of the cases. These tests were simulating real-life test scenarios with multiple ride requests flowing through their ride lifecycle. In production scenarios, we could not afford even 1% of real-time communication failure. 

With just a month to go for planned UAT – we decided to report this to AWS and troubleshoot. We tried various options of troubleshooting based on materials, the internet, and the options suggested by the AWS support team, but the issue was not resolved. Though the AWS support team was helpful, they were not sure about the resolution time and hence had no option but to start looking for alternatives.

Option 3 – Firebase:

During the design phase, we had successfully completed the proof-of-concept for Firebase as well. Initially, we did not choose Firebase since we favored the usage of AWS stack for the whole solution. However, the failure scenarios in Appsync left us with no option but to change our real-time communication framework to Firebase. 

Hence we started the re-development of the real-time communication module using Firebase, with less than one month to go into UAT.  The same data stores which were designed for real-time communication in Appsync were converted as nodes in Firebase. We designed methods to integrate the real-time data from Firebase into DynamoDB. As soon as we completed the development of a few important real-time communication APIs, we started the integration tests with real-life test simulations. We noticed that there were no failures in real-time communication for Firebase, even when 3 times the peak load size was tried out. All the real-time operations like Book Ride, Ride Accept, Passenger Cancel, and Driver Cancel were executed successfully. The ride status and location updates were synchronized between the mobile applications and server-side APIs without failures. The load testing was successful for all test cases for different concurrent requests executed using JMeter and automated test scripts. Firebase could handle the real-time communication scenarios expected from the solution. UAT phase was successful, and the application was moved to production without any issues.

In Conclusion

The road to building a successful application is not a walk in the park, but with the right team of experts who are passionate about getting it right, any challenge can be successfully overcome. 

Experion’s adept team overcame the hurdles they faced while building this solution suite with ease- they showed a pragmatic use of technical and domain expertise and ensured the product went live in record time, completely unhassled by the time-crunch they were met with.

So the next time you open a ride-hailing app on your phone, spare a smile for all the engineers, developers, and designers who made this convenience possible for you.
