Mobility is an important part of daily life. Progressive community planning and transportation design can greatly reduce the need for automobile travel, instead providing a diverse range of active transportation alternatives.
This presentation on the CATCH project looks at how transportation-related data can be used to understand a city’s travel footprint and help to inform city planning and programs to promote individual behaviour change.
It reviews the findings and lessons learned from the ‘CATCH Project’ (Carbon Aware Travel Choice): a 2 million euro-funded project, involving 11 partners across 6 European Union countries, aimed to develop a knowledge platform to help urban communities move to less carbon-intensive transportation systems. This presentation touches on the important role of developing a system to compare and contrast best practices, identify the many motivators for change to low carbon mobility, and use tools for engaging the public and decision makers to support innovation and change.

Building smart green mobility in South Tyrol through an open data hubSpeck&Tech
ABSTRACT: For decades the traditional approach for solving mobility and transportation challenges has been based on the idea of creating new road or rail infrastructures. Thanks to the impressive enhancement of intelligent transportation systems (ITS) technologies, in the last years this approach is going into the direction of rather improving the efficiency of how available transportation infrastructure is used. New digital infrastructures allow all mobility actors (vehicles, pedestrians, sensors, traffic management centers) to cooperate together to achieve the ambitious goal of improving mobility, enhancing safety, reducing congestion and environmental impacts. But how can we achieve this and ensure that public and private actors efficiently work together? In South Tyrol we have tried to give an answer to these challenges through the implementation of an open data hub, which enables the real-time data / information exchange among all interested parties and fosters the multiplication of development of research & innovation projects between local companies, research centers and public organizations. After years of implementation, the Open Data Hub South Tyrol is now creating the premises for a new historical phase for mobility in the region, with concepts like Mobility-as-a-Service or environmental traffic management that are finally moving from research to deployment.
BIO: Roberto Cavaliere is an ITS Project Manager at NOI Techpark Südtirol / Alto Adige, a public-owned organization in the Italian alpine region of South Tyrol coordinating the NOI Tech Park and with the mission to drive and foster research & innovation in the region. Roberto is the reference person in NOI for all initiatives in the field of ITS and smart mobility and in the last 10 years has coordinated a relevant number of EU-funded projects in this field. His main interests cover cooperative systems, autonomous driving, ITS for the environment, mobility-as-a-service and sharing mobility, road weather information systems (RWIS).

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Trip Generation
• Relates the number of trips being produced from
a zone or site by time period to the land use and
demographic characteristics found at that
location.
• Assumptions:
– Trip-making is a function of land use
– Trips are made for specific purposes
– Different trip types are made at different times of the day
– Travelers have options available to them
– Trips are made to minimize inconvenience
– System modeling is based on Traffic Analysis Zones
and networks
• Poisson model often used
22. CEE320
Winter2006
Trip Distribution
• Connect trip origins and destinations
estimated by the trip generation models
• Different trip distribution models are
developed for each of the trip purposes for
which trip generation has been estimated
• Most common model in practice is the
"gravity model"
23. CEE320
Winter2006
Gravity Models
• Distribution of trips is:
– Proportional to the number of trips produced
and attracted by each zone
– Inversely proportional to the separation
between the origin and destination zones
• Widespread use because of its simplicity,
its reasonable accuracy and support from
the USDOT

Editor's Notes
Federal transportation legislation requires that a Metropolitan Planning Organization (MPO) be designated for each urbanized area with a population of more than 50,000 people in order to carry out the metropolitan transportation planning process, as a condition of Federal aid.
In 1990, the Washington State Legislature passed the Growth Management Act (ESHB 2929) authorizing the Regional Transporaton Planning Program. This program allows for the formation of Regional Transportation Planning Organizations (RTPOs). The primary functions of RTPOs are to develop regional plans and policies for transportation, growth management, environmental quality, and other topics determined by the RTPO; provide data and analysis to support local and regional decision making; build community consensus on regional issues through information and citizen involvement; build intergovernmental consensus on regional plans, policies and issues, and advocate local implementation; and provide planning and technical services on a contractual basis.

Short term plan tends to place no great demands on construction activities and therefore has no large capital requirements. The scale of the problem usually is quite limited and the analysis and evaluation, while being detailed, are usually simple in structure. This type of problem comes under the generic term Transportation systems management (TSM).
The Puget Sound Regional Council is an association of cities, towns, counties, ports, and state agencies that serves as a forum for developing policies and making decisions about regional growth and transportation issues in the four-county (Pierce, King, Snohomish and Kitsap) central Puget Sound region
What is a Highway of Statewide Significance?
The Revised Code of Washington (RCW) sets minimal criteria for HSS designation:
“This statewide system shall include at a minimum interstate highways and other statewide principal arterials that are needed to connect major communities across the state and support the state’s economy.”
The Washington State Transportation Commission expanded the criteria, an HSS roadway must also be:
A State Highway;
A Principal Arterial that is part of the National Highway System (NHS);
Rural routes serving statewide travel; and/or
Urban routes that are:
Statewide travel links to Rural HSS,
Connections to Principal Arterial Ferry Routes,
Long haul freight links - FGTS Class T1 and T2, and
Connections to ports - FGTS Class T1 and T2.
Designation of a route as HSS means:
Higher priority for improvement funding;
State has authority for setting level-of-service (LOS);
Highway segment is exempt from local transportation concurrency requirements;
Identified as an essential public facility;
Consideration for primary funding by a the RTID.

Our region’s growth is constrained by water on one side, mountains on the other, and things like wetlands and earthquake fault lines in between.
Transportation answers aren’t simple or cheap.
Custom fit: The beauty of Destination 2030 is it’s custom fit to our region – not just our topography but our cities, towns and neighborhoods. So in the end we can grow but still maintain our natural environment and quality of life.
The WSDOT team studied potential I-5 improvements to accommodate SR 520 traffic from the 8-Lane Alternative through downtown Seattle. Project investigations found that I-5, already over capacity, would be unable to handle traffic from the 8-Lane Alternative without considerable improvements. The 8-Lane Alternative will be in the SR 520 Bridge Replacement and HOV Project Draft EIS as a traffic/engineering appendix. Further environmental analysis of the 8-Lane Alternative will not be included in the Draft EIS. The 8-Lane Alternative may be further evaluated if the I-5 study identifies operational improvements on I-5 that would accommodate the SR 520 8-Lane Alternative.
WSDOT is assuming tolls to be a future means of funding the project. The Regional Transportation Investment District (RTID) - made up of King, Pierce and Snohomish counties - is also developing a potential long-term funding package for approval by the voters.
Trip productions and attractions are computed for each zone by land use
Trip Purposes
HBW – Home based work trip
HBNW – Home based nonwork trip
NHB – Non-home based trip
Usually computed using trip generation rates
