In order for a municipality to effectively service and engage its constituency, it must understand the composition of the communities within it. Up to the present, such demographic estimates for target populations have been obtained largely from census data or expensive, time-intensive surveys. In this paper, we use Twitter microblog content to estimate the gender makeup of commuting population...

Shortest paths on road networks can be efficiently calculated using Dijkstra’s algorithm (D). In addition to roads, multi-modal transportation networks include public transportation, bicycle lanes, etc. For paths on this type of network, further constraints, e.g., preferences in using certain modes of transportation, may arise. The regular language constrained shortest path problem deals with t...

This study assessed the effect of rural-urban transportation on agricultural produce in Ankpa Local Government Area of Kogi State, Nigeria. Primary data obtained from 90 rural farming households were analysed using frequency count, Ordinary Least Square (OLS) regression analysis and mean score from a 3 point Likert type of scale. Results of the study revealed that majority of the farmers were m...

Transportation terminal is the key node in transport systems. Efficient terminals can improve operation of passenger transportation networks, adjust the layout of public transportation networks, provide a passenger guidance system, and regulate the development of commercial forms, as well as optimize the assembly and distribution of modern logistic modes, among others. This study aims to clarif...

Public urban mobility systems are composed by several transportation modes connected together. Most studies in urban mobility and planning often ignore the multi-layer nature of transportation systems considering only aggregated versions of this complex scenario. In this work we present a model for the representation of the transportation system of an entire city as a multiplex network. Using t...

Navigating large, urban transportation networks is a complicated task. A user needs to negotiate the available modes of transportation, their schedules, and how they are interconnected. In this article we present a Natural Language interface for trip planning in complex, multimodal, urban transportation networks. Our objective is to provide robust understanding of complex requests while giving ...

As the recent development of the Physical Internet contributes to a more efficient usage of transportation and logistics technologies, the question arises whether these technologies may have a varying impact on countries’ economic performance. Thus, it is crucial to understand the drivers of transportation volume. In this paper we present a country-level analysis of the determinants of growth o...

BACKGROUND Changes in urban mobility play a major role in transforming metropolitan areas into healthier places. This study quantified the impact of changes in travel mode shift and trip distance on active and non-active transportation of working age adult population of São Paulo. METHODS AND FINDINGS Through different scenarios, we estimated the daily time spent in transportation per inhabit...

This paper studies a general two-stage scheduling problem, in which jobs of different importance are processed by one first-stage processor and then, in the second stage, the completed jobs need to be batch delivered to various pre-specified destinations in one of a number of available transportation modes. Our objective is to minimize the sum of weighted job delivery time and total transportat...

OpenTripPlanner was identified as the most promising open source multimodal trip planning software. OpenStreetMap, which provides mapping data to OpenTripPlanner, is one of the most well-known open source international repository of geographic data. General Transit Feed Specification, which provides transportation data to OpenTripPlanner, has been the standard for describing transit systems and...
