Under JST RISTEX S3FIRE program, we are trying to implement Smart Access Vehicle (SAV) Service in Hakodate. The project adopts the method of service science loop - the repeated cycle of observation, design and implementation. In this paper we report the completion of its first cycle, and discuss how the cycle improved our initial design. We first conducted person trip research in Hakodate. We chose 20 candidates of various age and occupation, and recorded their everyday movements for four months. We then analyzed the result and made a person trip model. The model was then fed into our multi-agent simulator for Hakodate public transportation system. We conducted a small field test with five vehicles for one week. The most significant achievement is that we confirmed that our design of SAV system works. We succeeded in automatically dispatching five vehicles for eleven hours without any significant trouble or human supervision.
1) The Bank Station Capacity Upgrade Project aimed to increase capacity and reduce journey times at Bank Station due to accelerating passenger growth exceeding 1.17 billion passengers per year by 2026.
2) An innovative contractor engagement (ICE) procurement model was used where contractors were given all project information upfront and evaluated based on their proposed solutions, rather than just cost. This led to an improved winning proposal.
3) The winning proposal included innovations like a 94m moving walkway, triple escalators everywhere, and a simpler power relocation scheme, reducing blockade time. Modelling showed vast improvements to journey times and congestion relief over the original scheme.
The document summarizes a meeting of the CAV Task Force. It includes an introduction, mission statement, and overview of autonomous vehicle levels from 0-5. The morning session covers introductions and a presentation on Miami-Dade County's "Ollie" pilot project with IBM. The afternoon will discuss deployment considerations, technology briefings, potential future projects, and priorities like safety and mobility. The task force aims to facilitate CAV projects and build community awareness of connected and autonomous vehicles.
This document describes an autonomous vehicle simulation project. It discusses the essential components of an autonomous vehicle like sensors, a main computer and controllers. It then describes the autonomous vehicle simulator which simulates these components in a virtual world and allows extracting experimental data and displaying the real-time simulation. The simulator is divided into a configuration manager and real-time simulation parts. The project will be released as open-source by the end of the year to allow further development and support different platforms running the same steering/control algorithms.
This document discusses how autonomous vehicle technology could significantly impact transportation planning and public transit. It notes that fully autonomous vehicles could be available by 2030 and ubiquitous by 2040. This would be hugely disruptive as current transportation models and infrastructure investments are based on human-driven vehicles. The document outlines different levels of vehicle automation and describes how different automation levels could change travel demand and models of vehicle ownership. It also discusses how autonomous vehicles could both threaten public transit ridership but also provide opportunities to enhance transit capacity and efficiency through technologies like bus platooning. The key recommendation is that transit agencies will need to adapt by leveraging connected and autonomous vehicle technologies while focusing service on corridors where transit can offer high people-moving capacity.
An autonomous vehicle works by planning a route and updating it every 10 minutes while controlling the lane, changing lanes, and matching the speed of surrounding vehicles. It calculates the speed and turn angle needed and controls the steering to turn only when in the right lane, while monitoring the situation and reacting emergently to sudden braking vehicles ahead, obstacles, or speeding vehicles behind or in adjacent lanes.

An autonomous vehicle uses sensors like radar, LIDAR, GPS and computer vision to navigate without human input. Radar uses radio waves to determine distance, speed and track objects. LIDAR uses lasers to precisely map physical features. GPS provides maps, directions and real-time traffic data. Computer vision allows the vehicle to analyze images of the road and environment. Together these technologies allow autonomous vehicles to drive itself, potentially reducing accidents.
How will driverless vehicles impact urban living and daily commutes? How should governments get involved?

The document discusses the history and development of autonomous vehicles. It begins with early prototypes in the 1970s and 1980s, including Japan's first autonomous car that could travel up to 30 km/h. Major milestones are DARPA challenges and demonstrations of road following and obstacle avoidance. The document outlines key technologies required for autonomous vehicles like sensors, navigation, motion planning, and actuation. Short term advantages include reducing traffic and allowing work or rest while traveling. Long term, autonomous vehicles could enable longer commutes, public transit reductions, and decreased emissions. Ethical implications around training, corporate control, and privacy are discussed.
Autonomous Vehicles - Impacts and OpportunitiesPeter Shannon
Autonomous vehicles can evolve to impact society in profound ways by challenging assumptions we have lived by for generations. This presentation (and the discussion it supports) will explore the new opportunities as well as the challenges of autonomous vehicles, from how they will impact individuals’ lives during early adoption to how they will remake the urban cityscape in the long term. We will explore the technology’s impact on the concepts of vehicle ownership, parking, travel planning, and other parts of our lives shaped today around humans at the wheel, as well as practical challenges to realizing the long term opportunities.
This document discusses how 5G networks and autonomous vehicles will enable the era of software-defined cars.

These capabilities could enable applications like platooning, autonomous driving in urban areas, and lane-less driving. The future of automakers may involve acting as mobility service providers through fleet management enabled by 5G connectivity.
CES 2014 - Autonomous Connected VehiclesAndreas Mai
The document discusses autonomous vehicles and how technology can transform transportation. It notes that autonomous vehicles could reduce transportation costs on average by $550-$420 per vehicle per year through reduced insurance, operation costs, and time spent in traffic. The document also discusses how consumers globally trust autonomous vehicles, especially in emerging markets, and how transportation and communication costs take a large portion of personal income in many countries that could potentially be reduced.
This document provides an overview of Sensotronic Brake Control (SBC), including:
1. The key components of SBC including the brake operating unit, traction system hydraulic unit, and control module.
2. How SBC works during normal braking to provide pedal feel and precise brake pressure control at each wheel.
3. Emergency braking operation which bypasses the brake pressure simulator for direct pressure to the front calipers.
4. Procedures for bleeding the brake system, activating SBC after deactivation, and diagnosing issues using SDS.
Designing Roads for AVs (autonomous vehicles)Jeffrey Funk
Autonomous vehicles (AVs) represent one of the most promising new technologies for smart cities and for humans in general. The problem is that cities will not realize the full benefits from AVs until roads are designed for them. Until this occurs, their main benefit will be the elimination of the driver and steering wheel, which will reduce the cost and increase the capacity of taxis; but even this impact will not occur for many years because of safety concerns. Thus, in the near term, the main benefit of AVs will be free time for the driver to do emails and other smart phone related tasks.
A better solution is to design roads for AVs or in other words, to constrain the environment for AVs in order to simplify the engineering problem for them. For example, designing roads so that all vehicles can be controlled by a combination of wireless communication, RFID tags, and magnets will reduce the cost of AVs and increase their benefits. Only AVs would be allowed on these roads, they are checked for autonomous capability at the entrance, and control is returned to the driver when an AV leaves the road. Existing cars can be retrofitted with wireless modules that enable cars to be controlled by a central system, thus enabling cars to travel closely together. The magnets and RFID tags create an invisible railway that keeps the AVs in their lanes while wireless communication is used for lane changing and exiting a highway (Chang et al, 2014; Le Quesne et al, 2014). These wireless modules, magnets and RFID tags will be much cheaper than the expensive LIDAR that is needed when AVs are mixed with conventional vehicles on a road.
The benefits from dedicating roads to AVs include higher vehicle densities, less congestion, faster travel times, and higher fuel efficiencies. These seemingly contradicting goals can be achieved because AVs can have shorter inter-vehicle distances even at high speeds thus enabling higher densities, lower congestion, and lower travel times. The less congestion and thus fewer instances of slow moving or stopped vehicles enable the vehicles to travel at those speeds at which higher fuel efficiencies can be achieved (Funk, 2015). In combination with new forms of multiple passenger ride sharing, the higher fuel efficiencies will also reduce carbon emissions and thus help fight climate change.
The challenge is to develop a robust system that can be easily deployed in various cities and that will be compatible with vehicles containing the proper subsystems. Such a system can be developed in much the same way that new cellular systems are developed and tested. Suppliers of mobile phone infrastructure, automobiles, sensors, LIDAR, 3D vision systems, and other components must work with city governments and universities to develop and test a robust architecture followed by the development of a detail design.
Sensotronic Brake Control (SBC) is an electronically controlled brake system that uses electric signals and a microcomputer to calculate optimal brake pressure at each wheel based on sensor inputs and driving situation. It replaces many mechanical components with electronic ones, using sensors to gauge brake pedal pressure and speed and send that data to the central control unit. SBC allows for more dynamic brake management and integration with other systems like ESP, providing benefits like faster emergency braking, improved stability, and increased brake comfort.
Autonomous vehicles use various sensors like ultrasonic sensors, RADAR, LIDAR, image sensors, GPS, and wheel speed sensors to navigate without human input. They rely on sensor integration and technologies like computer vision, V2X communication, and electronic control units to process sensor data. While self-driving cars offer benefits like safety and efficiency, there are also challenges to overcome like unpredictable humans, bad weather, and needing detailed digital maps. Fully autonomous vehicles may become common by 2040 if these issues can be addressed.
Sensotronic Brake Control (SBC) is an electro-hydraulic braking system introduced by Mercedes-Benz that allows for individual brake pressure control of each wheel. SBC uses a central control unit connected to sensors and valves to determine the optimal brake pressure for each wheel based on inputs like pedal position, vehicle motion, and inputs from the Electronic Stability Program. This precise control of brake pressure for each wheel provides benefits like reduced stopping distances, improved stability, and comfort features like soft stops and drive-away assist.
Smart infrastructure for autonomous vehicles Jeffrey Funk
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how autonomous vehicles are becoming economic feasible. They are becoming economically feasible because the cost of lasers, ICs, MEMS, and other electronic components are falling at 25 to 40% per year. If the cost of autonomous vehicles fall 25% a year, the cost of the electronics associated with autonomous vehicles will fall 90% in 10 years. Dedicating roads to autonomous vehicles is necessary to achieve the most benefits from autonomous vehicles. While using autonomous vehicles in combination with conventional vehicles can free drivers for other activities, dedicating roads to autonomous vehicles can dramatically reduce congestion, increase speeds, and thus increase the number of cars per area of the road. They can also reduce accidents, insurance, and the number of traffic police. These slide discuss the use of wireless technologies for the control and coordination of autonomous vehicles. Improvements in bandwidth, speed, and latency (delays) along with improvements in computer processing are occurring and these improvements are making dedicated roads for autonomous vehicles economically feasible.
This document discusses autonomous vehicles and the companies working on them. It defines autonomous vehicles as vehicles that can travel from one point to another without human interaction. The top companies working on autonomous vehicles are Google, Intel, General Motors, Mercedes Benz, and Audi. Autonomous vehicles use technologies like lidar, radar, cameras and sensors to navigate and detect obstacles without human assistance. They have potential to reduce accidents by eliminating human error.

These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how autonomous vehicles are becoming economically feasible throug through improvements in lasers, microelectronic mechanical systems (MEMS), integrated circuits (ICs), and other components. Although the cost of the Google Car is currently about 150,000 USD, 30% annual improvements in lasers, MEMS, and ICs will make these economically feasible for a broad number of users in the next ten years. A key issue is when certain lanes, roads or even entire highway systems are restricted to automated vehicles. This would enable collision avoidance to rely more on between-vehicle communications. This would further reduce the cost of automated vehicles, stimulate diffusion, and also reduce transportation time and increase fuel efficiency.

This document discusses the future development of traffic signals and the impact of autonomous vehicles. It begins with a brief history of traffic signal technology and then discusses where the technology is now.

An autonomous underwater vehicle (AUV) is a robot which travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications AUVs are more often referred to simply as unmanned undersea vehicles (UUVs).
The document discusses sensotronic braking systems (SBC), which use electronic sensors and controls rather than mechanical linkages. SBC was developed by Robert Bosch and Mercedes-Benz to provide faster, more precise braking control through analyzing sensor data on wheel speeds, pedal pressure, steering angle and other factors. Key components include a microcomputer, hydraulic units to control pressure at each wheel, and sensors on the pedal, wheels, steering and hydraulic units. SBC allows for functions like emergency braking assistance, stability control, and optimized braking in turns. It could enable future autonomous vehicle guidance systems.

Safe Driving Advisor and Evaluator.pptxHazem Fahmy
We developed a model predictive control -based simulator using differential equations and realizing a final simulation loop system mimicking vehicle dynamics, driver behavior, road geometry, and a decision-making system. The simulator is developed in Wolfram Mathematica and relies on a symbolic numerical approach to optimize a vehicles track (represented as a cost function) for autonomous driving enabling lane-keeping, collision-avoidance, path-planning, and decision-making features while assessing and reducing the risk associated to the vehicle by providing warnings and interventions when a crash is imminent.
The document describes a lane test conducted at the Automotive Lab of Salahaddin University. The test used a VIDEO-COMBI line 2204/2304 device to evaluate various systems of passenger cars. The device includes a brake diagnosis unit, chassis testing unit, and fast track tester. The lane test consisted of three parts: (1) measuring track deviation using the fast track tester; (2) testing suspension systems using the chassis testing unit; and (3) evaluating brake systems using the brake diagnosis unit. The document concludes with a request to briefly discuss car suspension and brake systems.
The document proposes a new certification scheme for automated/autonomous vehicles that considers the increased complexity and scenarios that cannot be fully tested on tracks or benches. The concept includes three pillars: 1) An audit of the development process and safety concept. 2) Physical certification tests of critical scenarios. 3) A real-world test drive to assess overall capabilities. Together these evaluate if the system was designed safely and performs comparable to an experienced driver. Simulation is also used to test variations that are difficult to assess otherwise. The approach aims to demonstrate safety for market introduction in a flexible way that allows for continued technology evolution.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
