We present a new algorithm to find optimal routes in a multi-modal public transportation network. This work is an extension of recent work on finding multi-criteria optimal paths in multi-modal public transportation networks [8] using the ideas of TRANSIT algorithm [4]. As a preprocessing step, we identify hub stations, a relatively small subset of all stations and then precompute optimal paths...

Traffic counting devices are commonly used by governmental agencies and private companies in order to assess traffic patterns and the level of occupancy of roadway networks. The data provided by these devices normally encompasses traffic volumes, vehicle classes and vehicle speeds, and are used by traffic engineers in the planning, design and operations of transportation systems. An evaluation ...

BACKGROUND This report describes changes in the percentage of US students (age 5 to 18 years) who walked or bicycled to school and in the distance that they lived from or traveled to their school in 1969 and 2001 and travel patterns in 2001. METHODS Data were from the 1969 National Personal Transportation Survey report on school travel and the 2001 National Household Transportation Survey. ...

We study networks that connect points in geographic space, such as transportation networks and the Internet. We find that there are strong signatures in these networks of topography and use patterns, giving the networks shapes that are quite distinct from one another and from non-geographic networks. We offer an explanation of these differences in terms of the costs and benefits of transportati...

In urban public transport, smart card data is made of millions of observations of users boarding vehicles over the network across several days. The issue addresses whether data mining techniques can be used to study user behaviour from these observations. This must be done with the help of transportation planning knowledge. Hence, this paper presents a common “transportation planning/data minin...

An analysis pattern is any part of a requirement analysis specification that can be reused in the design of other information systems as well. Urban management systems (e.g.: Tax Control Systems, Urban Transportation System) are implemented in a similar way for many counties. This paper proposes three analysis patterns that make possible the reuse of geographic database design for urban area pl...

Integrated solutions for product delivery planning and scheduling in distribution centres are proposed and built on a cluster analysis and simulation optimisation methodology. A cluster analysis of product demand data of stores is used to identify typical dynamic demand patterns and product delivery tactical plans. Further, simulation optimisation techniques are applied to find optimal paramete...

Public-transportation route-planning systems typically work as follows. The user specifies a source and a target location, as well as a departure time. The system then returns one or more optimal trips at or after that departure time. In this paper, we consider guidebook routing, where the goal is to provide timeindependent answers that are valid over long periods of time. An example answer cou...

Evidence of the health impacts of the built environment has increased rapidly. Studies have linked physical inactivity and motor-vehicle pollution to a range of health problems and have shown that activity levels and air quality are influenced by community design, land use, and transportation patterns. There is comparatively little awareness, however, of the role that laws and policies play in ...
