Shared-Use Bus Priority Lanes On City Streets: Case Studies in Design and Management, MTI Report 11-10
This report examines the policies and strategies governing the design and, especially, operations of bus lanes in major congested urban centers. It focuses on bus lanes that operate in mixed traffic conditions; the study does not examine practices concerning bus priority lanes on urban highways or freeways. Four key questions addressed in the paper are: How do the many public agencies within any city region that share authority over different aspects of the bus lanes coordinate their work in designing, operating, and enforcing the lanes? What is the physical design of the lanes? What is the scope of the priority use granted to buses? When is bus priority in effect, and what other users may share the lanes during these times? How are the lanes enforced? To answer these questions, the study developed detailed cases on the bus lane development and management strategies in seven cities that currently have shared-use bus priority lanes: Los Angeles, London, New York City, Paris, San Francisco, Seoul, and Sydney. Through the case studies, the paper examines the range of practices in use, thus providing planners and decision makers with an awareness of the wide variety of design and operational options available to them. In addition, the report highlights innovative practices that contribute to bus lanesâ success, where the research findings make this possible, such as mechanisms for integrating or jointly managing bus lane planning and operations across agencies
Towards Smarter Management of Overtourism in Historic Centres Through Visitor-Flow Monitoring
Historic centres are highly regarded destinations for watching and even participating in diverse and unique forms of cultural expression. Cultural tourism, according to the World Tourism Organization (UNWTO), is an important and consolidated tourism sector and its strong growth is expected to continue over the coming years. Tourism, the much dreamt of redeemer for historic centres, also represents one of the main threats to heritage conservation: visitors can dynamize an economy, yet the rapid growth of tourism often has negative effects on both built heritage and the lives of local inhabitants. Knowledge of occupancy levels and flows of visiting tourists is key to the efficient management of tourism; the new technologiesâthe Internet of Things (IoT), big data, and geographic information systems (GIS)âwhen combined in interconnected networks represent a qualitative leap forward, compared to traditional methods of estimating locations and flows. A methodology is described in this paper for the management of tourism flows that is designed to promote sustainable tourism in historic centres through intelligent support mechanisms. As part of the Smart Heritage City (SHCITY) project, a collection system for visitors is developed. Following data collection via monitoring equipment, the analysis of a set of quantitative indicators yields information that can then be used to analyse visitor flows; enabling city managers to make management decisions when the tourism-carrying capacity is exceeded and gives way to overtourism.Funded by the Interreg Sudoe Programme of the European Regional Development Funds (ERDF
Code, space and everyday life
In this paper we examine the role of code (software) in the spatial formation of
collective life. Taking the view that human life and coded technology are folded into
one another, we theorise space as ontogenesis. Space, we posit, is constantly being
bought into being through a process of transduction â the constant making anew of a
domain in reiterative and transformative practices - as an incomplete solution to a
relational problem. The relational problem we examine is the ongoing encounter
between individuals and environment where the solution, to a greater or lesser extent,
is code. Code, we posit, is diversely embedded in collectives as coded objects, coded
infrastructure, coded processes and coded assemblages. These objects, infrastructure,
processes and assemblages possess technicity, that is, unfolding or evolutive power to
make things happen; the ability to mediate, supplement, augment, monitor, regulate,
operate, facilitate, produce collective life. We contend that when the technicity of
code is operationalised it transduces one of three forms of hybrid spatial formations:
code/space, coded space and backgrounded coded space. These formations are
contingent, relational, extensible and scaleless, often stretched out across networks of
greater or shorter length. We demonstrate the coded transduction of space through
three vignettes â each a day in the life of three people living in London, UK, tracing
the technical mediation of their interactions, transactions and mobilities. We then
discuss how code becomes the relational solution to five different classes of problems
â domestic living, travelling, working, communicating, and consuming
Hierarchical video surveillance architecture: a chassis for video big data analytics and exploration
There is increasing reliance on video surveillance systems for systematic derivation, analysis and interpretation of the data needed for predicting, planning, evaluating and implementing public safety. This is evident from the massive number of surveillance cameras deployed across public locations. For example, in July 2013, the British Security Industry Association (BSIA) reported that over 4 million CCTV cameras had been installed in Britain alone. The BSIA also reveal that only 1.5% of these are state owned. In this paper, we propose a framework that allows access to data from privately owned cameras, with the aim of increasing the efficiency and accuracy of public safety planning, security activities, and decision support systems that are based on video integrated surveillance systems. The accuracy of results obtained from government-owned public safety infrastructure would improve greatly if privately owned surveillance systems âexposeâ relevant video-generated metadata events, such as triggered alerts and also permit query of a metadata repository. Subsequently, a police officer, for example, with an appropriate level of system permission can query unified video systems across a large geographical area such as a city or a country to predict the location of an interesting entity, such as a pedestrian or a vehicle. This becomes possible with our proposed novel hierarchical architecture, the Fused Video Surveillance Architecture (FVSA). At the high level, FVSA comprises of a hardware framework that is supported by a multi-layer abstraction software interface. It presents video surveillance systems as an adapted computational grid of intelligent services, which is integration-enabled to communicate with other compatible systems in the Internet of Things (IoT)
VANET Applications: Hot Use Cases
Current challenges of car manufacturers are to make roads safe, to achieve
free flowing traffic with few congestions, and to reduce pollution by an
effective fuel use. To reach these goals, many improvements are performed
in-car, but more and more approaches rely on connected cars with communication
capabilities between cars, with an infrastructure, or with IoT devices.
Monitoring and coordinating vehicles allow then to compute intelligent ways of
transportation. Connected cars have introduced a new way of thinking cars - not
only as a mean for a driver to go from A to B, but as smart cars - a user
extension like the smartphone today. In this report, we introduce concepts and
specific vocabulary in order to classify current innovations or ideas on the
emerging topic of smart car. We present a graphical categorization showing this
evolution in function of the societal evolution. Different perspectives are
adopted: a vehicle-centric view, a vehicle-network view, and a user-centric
view; described by simple and complex use-cases and illustrated by a list of
emerging and current projects from the academic and industrial worlds. We
identified an empty space in innovation between the user and his car:
paradoxically even if they are both in interaction, they are separated through
different application uses. Future challenge is to interlace social concerns of
the user within an intelligent and efficient driving

Gender differences in responses to speed cameras: Typology findings and implications for road safety
Automated speed cameras in England and Wales have become a very common means of enforcement of speed limit breaches in most police force areas, but they are not without controversy despite the majority of public opinion behind them. Research in the mid-1990s showed that drivers responded to speed cameras in one of several key ways, and the typology of responses produced was linked with driversâ characteristics. Now that women comprise more than 4 out of 10 licensed drivers in England and Wales, it is timely to revisit the earlier research by considering the gender characteristics of the driver typology, and this paper contrasts the results longitudinally with those obtained from a 2003 survey that inter alia explored similar issues. The implications for road safety of the behavioural and attitudinal differences noted by gender (and age) are discussed, especially in the context of risk-based control policies and the term âdriversâ. This latter aspect is achieved by way of a brief analysis of national newspaper articles
