Taxi as a door-to-door, all-weather way of travel is an important part of the urban transportation system. A fundamental understanding of temporal-spatial variation and its related influential factors are essential for taxi regulation and urban planning. In this paper, we explore the correlation between taxi demand and socio-economic, transport system and land use patterns based on taxi GPS trajectory and POI (point of interest) data of Qingdao City. The geographically weighted regression (GWR) model is used to describe the influence factors of spatial heterogeneity of the taxi demand and visualize the spatial distributions of parameter estimations. Results indicate that during the peak hours, there are some differences in taxi demand between workdays and weekends. Residential density and housing prices increase the number of taxi trips. Road density, parking lot density and bus station density are positively associated with the taxi demand. It is also found that the higher of the proportion of commercial area and public service area, the greater of the taxi demand, while the proportion of residential area and the land use mix have a negative impact on taxi demand. This paper provides some references for understanding the internal urban environmental factors generating from the taxi travel demand, and provides insights for reducing the taxi vacancy rate, forecasting taxi temporal-spatial demand and urban public transportation system planning.

Transportation systems play a central role in a sustainable society by providing mobility for people, goods, and services. Significant sustainability benefits are being derived through the improvements in transportation network efficiency, use of alternative modes and multimodality, integration of sustainable design, better integration of land use and transportation systems. Sustainable transportation system usually refers to any means of transportation which has low impact on the environment, affordable to users and can balance the current and future needs. This work covers the implementation of surveying techniques in the route selection for Baghdad Metro Tube. The travel demand has been assessed through an extensive travel potential survey. The public bus terminals were considered as a major source of data. The number of passengers using the present public transportation system from each bus terminal and for each route to various destinations has been recorded. The passenger supply points have been indicated by latitude and longitude that define the bus stop and the proposed metro route using global positioning system GPS. A passenger counting data was collected concerning the present use of public transport. A line indicates travel from one area to another and a grid was constructed. The present bus routes were identified, and the 28 major and minor public transportation terminals, which represent the passenger trip origin and destination nodes, were detected using GPS. The bus terminals were also positioned by the GPS and affixed. The recent land use of Baghdad urban area and the existing transportation network as obtained from Google earth were utilized in the geographic information system GIS environment. Travel corridors are identified and analyzed according to their existing right-of-way conditions, transit services, land use, and demographics.The positive and negative attributes of each corridor with regards to their potential for supporting transitoriented development TOD and higher capacity transit services have been determined through optimization process in the GIS. Finally, five corridors of the highest trip potential have been selected and proposed.

Transit Use

The configuration of urban areas is the result of a cyclic relationship between land use and transportation system: the changes in transportation system arrangements influence the localisation of residence and economic activities, as well as the changes in land use affect transportation system characteristics. In this context, by operating on land use, travel demand can be shift from the individual transportation modes to transit systems. In the literature, many conceptual models were proposed to describe the complex relationship between land use and travel behaviour. In addition to spatial variation, the study of travel demand shows the categorical variation of variables. This work aims to analyse the influence of the categorical variation of variables impacting on transit use. An ordered probit model is proposed for evaluating how transit use depends on variables related to socio-economic characteristics of population, territorial features, accessibility, and transportation system. The study case is Madrid metro network (Spain). The results show a strong influence of characteristics of population and land use variables on daily trips made using metro system and highlighted the aspects that mainly impact on the choice to travel by metro, providing useful suggestions for shifting people from individual transportation mode to transit systems.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3205

The Impact

AbstractMoving along with daily life, urban residents and commuters create characteristic spatiotemporal patterns which vary extensively with the time of day. These patterns are formed via traffic flows: accordingly, understanding the impact of transportation system is essential for urban planners to evaluate expected urban activities. To explore them, we examine specifically population distributions in Seoul City by analyzing hourly population data based on mobile phone location records in combination with a couple of indicators of the Seoul Subway system. Through clustering and principal component analyses, we first demonstrate that the spatial distribution of the population is categorized according to the time of day, i.e., night, daytime, and evening, variations across which reflect the morphology of land use. We then examine the influence of the subway system on the population, employing ridership and accessibility as indicators. Our linear regression analysis shows that both are associated with the daytime and the evening populations, which implies that only commercial activities are substantially coupled to the subway system. Further, we find that the distinctive difference of night population is encoded in the probability distributions; this is elucidated by means of a multiplicative growth model for the morphological evolution of Seoul, revealing decentralization of residential areas and centralization of commercial areas. This study sheds light on the interplay of a public transportation system and land use, which is of relevance to planners and policymakers wishing to develop neighborhoods in support of sustainable modes.

Abstract Aquaculture, particularly shrimp farming in the Kandaleru creek area, has shown spectacular growth within the last two decades. However, economic prosperity which was the driving force for shrimp farming expansion, has also had a significant negative impact on land use changes and creek water quality causing shrimp health hazards. Using a hypothesis that the discharge of shrimp farming effluents may have exceeded the carrying capacity (CC) of the creek water, the environmental CC of Kandaleru creek was assessed based on total nitrogen (TN) input. Remote sensing (RS) and image enhancement techniques integrated with geographical information systems (GIS) were applied to quantify and determine the changes in land use patterns in the creek area. GIS and a numeric model were used to compute the TN load in three different salinity zones to determine the CC status. The study revealed that exceeding the CC of the creek along with increasing shrimp farms, decreasing natural resources and changes in land use patterns.

Although Khulna's actual history is not about more than 200 years, but it has a 2000 years settlement and commercial history. Khulna was a part of Ganaridai, Vanga, Jessore dynasty, Rarh (South Bengal) in different periods. The connection of rivers always made a blessing for Khulna for water transportation to accelerate trade and commerce. According to Ptolemy, the ancient Gangaridai had an ancient port located in greater Jessore [1,557]. Some archaic incidents, verses, and legends of Mani-Rishis (Ancient Indian Scholars) proved the old settlement and commercial style. The chronological evolution of the ancient Period (6th century BC – 1757 AD) described a civilization's development with the incremental commercial approach [2,315]. The colonial regime can relate to the evolution of a commercial and economic center like Barobazar as a whole. All these chronological narrations, consecutive phenomena, and influential factors will depict the trend of retail evolution. The research aims to describe Khulna's commercial development's sequential affairs and find the missing links between eras. Various ancient documents, Blueprints, Greek Periplus, etc. will describe the settlement, commercial mode, and history. It will determine the answer to the questions about the growth and establishment of river port cities and major economic centers' evolution. The paper will describe commercial –spatial progression in 4 Particular eras. GIS surveys and some old maps will illustrate the commercial land-use patterns of Barobazar from the Colonial Period to the present and the river base trade. These will elaborate on the existing conditions as well as the revolutionary changes. The fundamental research will help for the further Urban regeneration of Barobazar as a central economic hub. The historical consequences will help to sort out the development pattern and strategies behind the progression.

License plate restriction (LPR) policy presents the most straightforward way to reduce road traffic and emissions worldwide. However, in practice, it has aroused great controversy. This policy broke the original structure of the urban transportation mode, which needed some matching strategies to adapt to this change. Investigating this travel demand change is a challenging task because it is greatly influenced by features of the local built environment. Fourteen variables from four dimensions, location, land-use diversity, distance to transit, and street design, are used to depict the built environment; moreover, the severe collinearity underlies these feature variables. To solve the multicollinearity among the variables and high-dimensional problem, this study utilizes two different penalization-based regression models, the LASSO (least absolute shrinkage and selection operator) and Elastic Net regression algorithms, to achieve the variable selection and explore the impacts of the built environment on the change of travel demand triggered by the LPR policy. Travel demand changes are assessed by the relative variation in taxi ridership in each traffic analysis zone based on the taxi GPS data. Built environment variables are measured using the transportation network data and the Baidu Map Service points of interest (POI) data. The results show that regions with a higher level of public transportation service and a higher degree of the land mix have a stronger resilience to the vehicle restriction policy. Besides, the contribution rate of public transportation is stable as a whole, while the contribution rate of richness depends on specific types of land use. The conclusions in this study can provide in-depth insights into the influence of the LPR policy and underpin traffic complementary policies to ensure the effectiveness of LPR.

Kinds of urban transportation policy are used to overcome public transportation's problemin big cities. One of them is the development of public transportation based on railways.This policy has already implemented in J abodetabek as public transportation besides buses.The potency of J abodetabek railways development can be seen from the trends of passengersand land use patterns. In addition, the synergy of settlement area in cities and railwaysdevelopment can be seen as potency as well. The cooperation between PT.KA and privatecompanies has already exists and can be improved by considering the potency. The growthsof those settlements area refers to the regional planning which can take advantage fromthe railways track through on the area, conversely PT.KA will gain profit from the passengerswho stay in that area. This matter is explained in the study of The Synergy of UrbanRailways Network and Settlement Property conducted by Research and Development ofTransportation Agency in 2008.
