Regional traffic impacts of logistics-related land use

The outsourcing of logistics activities to logistics service providers leads to a demand for new logistics-related land development. At the moment (minimising) regional traffic generation is not a major decision criterion for site selection and development. For a sound traffic impact assessment, information on trip generation of logistics facilities like transfer depots, distribution centres and warehouses is necessary. Surveys conducted in the case study region Hamburg, Germany, provide such information. Applying the survey results, different logistics land use development scenarios are assessed in this paper. The results show that strategic location of logistics areas can reduce traffic and traffic impacts.     

Environmental complexity related information for the assessment of country logistics environments: Implications for spatial transaction costs and foreign location attractiveness

With on-going fragmentation and distribution of production and consumption across geographical space, information about national logistics systems is becoming increasingly important to decision makers in internationally operating firms and organisations. While continuing research on country logistics assessment generates some of this information, its relevance for the decision makers, and relationship to their unpredictability from foreign national logistics systems remains indefinite.This paper identifies and categorises the relevant, available information on country logistics environments by using a content analysis approach. We demonstrate the immensity and nature of this information, are able to confirm the changing spatial transaction cost structures, and to reflect upon the overall conditions of information-related complexity and globalisation in the environment. Besides making a contribution to the further development of the spatial impedance factors and measures that form the basis for decision maker unpredictability, the paper offers an alternative approach for measuring the importance of transportation costs in industrial location, and offers a useful lens to distinguish between the emerging literatures on national logistics systems. Finally the paper also offers practical implications on location attractiveness for investment promotion agencies and other public sector agencies for business development and cluster growth.

Modeling job accessibility using online map data: An extended two-step floating catchment area method with multiple travel modes

Current quantitative measures of job accessibility rarely consider the interaction between job opportunities and labor force, and the effects of dynamic travel mode choice. Drawing upon multiple open-source datasets, we develop a job accessibility index by extending the two-step floating catchment area method (2SFCA). The job accessibility indices are calculated for different commuting scenarios concerning distance, time, and travel modes. The results suggest that job accessibility is very sensitive to travel modes, and using a single travel mode would contribute to a biased job accessibility index. The job accessibility indices with combined travel modes are more geographically balanced than using a single travel mode. Furthermore, the new index is employed to examine the spatial pattern of job accessibility and explore the relationship between job accessibility, housing, and population in the Pudong district, Shanghai. The new job accessibility indices manifest the impacts of ring roads on the spatial distribution of job accessibility. A comparative analysis shows that the floating population has poor driving-based job accessibility but can access job opportunities using public transit. Also, poor job accessibility leads to low rent prices but has little impact on medium-high rent. Both transit-based and drive-based job accessibility indices are positively related to housing prices. Our study highlights the importance of considering dynamic travel mode choice in job accessibility research. The research outcomes also contribute to the literature on spatial mismatch by revealing the unique relationship between job accessibility, housing, and population in urban China.

Ant colony optimization for disaster relief operations

This paper presents a meta-heuristic of ant colony optimization (ACO) for solving the logistics problem arising in disaster relief activities. The logistics planning involves dispatching commodities to distribution centers in the affected areas and evacuating the wounded people to medical centers. The proposed method decomposes the original emergency logistics problem into two phases of decision making, i.e., the vehicle route construction, and the multi-commodity dispatch. The sub-problems are solved in an iterative manner. The first phase builds stochastic vehicle paths under the guidance of pheromone trails while a network flow based solver is developed in the second phase for the assignment between different types of vehicle flows and commodities. The performance of the algorithm is tested on a number of randomly generated networks and the results indicate that this algorithm performs well in terms of solution quality and run time.
