Transitioning to a Connected and Automated Vehicle Environment: Opportunities for Improving Transportation

Harper, Corey David 01 August 2017 (has links)
Over the past few years automotive and technology companies have made significant advances in what has been traditionally a completely human function: driving. Crash avoidance features such as lane departure warning and forward collision warning are becoming increasingly more common and cheaper to obtain, even on non-luxury vehicles. Technology companies and auto manufacturers have announced plans to have self-driving vehicles ready for public use as early as 2020. The mass adoption of automated vehicles (AVs) could significantly change surface transportation as we know it today. This thesis is intended to provide a technical analysis of the potential impacts of AVs on current light-duty vehicle miles traveled (VMT) and parking decisions, the economic desirability of widespread deployment of partially automated technologies, and methods for existing roadways to transition to connected and automated vehicle (CAV) transportation, so that policymakers can make more informed decisions during the transition to CAVs. This work takes a look at AVs from a point in time where vehicles are equipped with driver assistance systems (Level 1) to a point in time where AVs are driverless (Level 5) and can self-park. The results of this work indicate that the fleet-wide adoption of partially automated crash avoidance technologies could provide net-benefit of about $4 billion at current system effectiveness and could provide an annual net-benefit up to $202 billion if all relevant crashes could be prevented. About 25% of all crashes could be addressed by the crash avoidance technologies examined in this dissertation. Over time, as technologies become more effective and cheaper due to economies of scale, greater benefits than the $4 billion could be realized. As automated technologies become more advanced and widespread, existing roadways will need to be able to accommodate these vehicles. This work investigates the effects of a dedicated truck platoon lane on congestion on the Pennsylvania Turnpike and provides a method for existing roadways and highways to determine viable platoon demonstration sites. The initial results suggest that there are several sections of turnpike that could serve as commercial truck platoon demonstration site while still providing a high LOS to all other vehicles. Once AVs can safely and legally drive unoccupied, vehicles will no longer be limited to their driver’s destination and can search for cheaper parking in more distant parking locations. This work simulates a fleet of privately owned vehicles (POVs) in search of cheaper parking in Seattle, using a rectangular grid throughout the study area. Model results indicate that we are not likely to see significant increase in vehicle miles traveled (VMT) and energy use from cars moving from downtown parking lots to cheaper parking in distance locations but at higher penetration rates, parking lot revenues could likely decline to the point where operating a lot is unsustainable economically, if no parking demand management policies are implemented. Driverless vehicles also promise to increase mobility for those in underserved populations. This work estimates bounds on the potential increases in travel in a fully automated vehicle environment due to an increase in mobility from the non-driving and senior populations and people with travel-restrictive medical conditions. Three demand wedges were established in order to conduct a first-order bounding analysis. The combination of the results from all three demand wedges represents an upper bound of 295 billion miles or a 14% increase in annual light-duty VMT for the US population 19 and older. AV technology holds much promise in providing a more accessible and safe transportation system. This thesis can help policymakers and stakeholders maximize the benefits and minimize the challenges.

Travellers’ preference for parking at the Vancouver International Airport

Romank, Heather 11 1900 (has links)
Market research is becoming an increasingly important part of an airport's operational strategies as airport managers try to increase customer service and reach operational goals. This research applies conjoint analysis to investigate customer preferences for parking facilities and services at a major Canadian airport. This research will define and determine the relative importance of a set of attributes which influence business travelers' parking choice at the Vancouver International Airport. In addition, market segments for parking services will be identified. Sawtooth Software's Adaptive Conjoint Analysis and Ci2 were used in this study. A questionnaire was administered to a 36 employees among three local companies selected for data collection. Employees of these three companies represented potential local business travelers. This study was limited to the investigation of a subset of traveler (i.e. business traveler) preferences for parking at the Vancouver International Airport. More complete analysis would have to replicate the data collection procedures and target different users under different conditions (i.e. time of day, time of year, duration of stay). Results of the conjoint analysis indicated that price and distance to the terminal building account about equally for the majority of business travelers parking preference ratings (approximately two-thirds). The provision of video camera security was also an important determinant of customer preference. The provision of electronic signage providing guidance to available parking spaces did not contribute significantly to customer preference. In addition, the provision of a parkade rather than a surface lot contributed little to customer preference. Market share estimates were calculated for YVR's proposed Parkade, Main and Economy parking lots. Estimates of market shares suggested that a majority of business travelers taking an overnight journey in August preferred to park in the YVR Parkade. Market share estimates were also calculated for various service alternatives in the parkade. Comparing these additional estimates with the base service option revealed the trade-offs that business travelers were likely to make. Results anticipated approximately a 60 percent market share for the proposed parkade service despite charging a higher price ($6 per day higher than the alternative parking lots). Market share estimates predicted that the provision of video camera security and electronic signage in the parkade was significant in enabling a higher price. The predicted market share falls substantially to 28 percent if security and signage are not provided. Results also suggested that more travelers were willing to pay extra for the provision of video camera security than electronic signage in the parkade. / Business, Sauder School of / Operations and Logistics (OPLOG), Division of / Graduate

Understanding Traffic Cruising Causation : Via Parking Data Enhancement

Jasarevic, Mirza January 2021 (has links)
Background. Some computer scientists have recently pointed out that it may be more effective for the computer science community to focus more on data preparation for performance improvements, rather than exclusively comparing modeling techniques.Testing how useful this shift in focus is, this paper chooses a particular data extraction technique to examine the differences in data model performance. Objectives. Five recent (2016-2020) studies concerning modeling parking congestion have used a rationalized approach to feature extraction rather than a measured approach. Their main focus was to select modeling techniques to find the best performance. Instead, this study picks a feature common to them all and attempts to improve it. It is then compared to the performance of the feature when it retains the state it had in the related studies. Weights are applied to the selected features, and altered, rather than using several modeling techniques. Specifically in the case of time series parking data, as the opportunity appeared in that sector. Apart from this, the reusability of the data is also gauged. Methods. An experimental case study is designed in three parts. The first tests the importance of weighted sum configurations relative to drivers' expectations. The second analyzes how much data can be recycled from the real data, and whether spatial or temporal comparisons are better for data synthesis of parking data. The third part compares the performance of the best configuration against the default configuration using k-means clustering algorithm and dynamic time warping distance. Results. The experimental results show performance improvements on all levels, and increasing improvement as the sample sizes grow, up to 9% average improvement per category, 6.2% for the entire city. The popularity of a parking lot turned out to be as important as occupancy rates(50% importance each), while volatility was obstructive. A few months were recyclable, and a few small parking lots could replace each other's datasets. Temporal aspects turned out to be better for parking data simulations than spatial aspects. Conclusions. The results support the data scientists' belief that quality- and quantity improvements of data are more important than creating more, new types of models. The score can be used as a better metric for parking congestion rates, for both drivers and managers. It can be employed in the public sphere under the condition that higher quality, richer data are provided.
