Passengers and Freight Movements by Time of the Day: Contradictions
Freight and the City • For freight, cities have three major dimensions • Cities are zones of production: • Industrial location. • Cities are transport nodes: • Accumulation of transport terminals. • Intermediary locations. • Cities are zones of consumption: • Problem of urban distribution. • Dislocation between those functions • Notably between production, distribution and consumption. • Brought by globalization, global production networks and efficient freight transport systems (increasingly by logistics).

Assets (Freight Transport) Privately owned (profit motivated). Relatively low entry costs (wages and rates subject to market forces). Value added function (trade distance for cost). Support industrial, manufacturing and commercial activities. Liabilities (Public Transit) Publicly owned (politically motivated). Little or no competition permitted (wages and fares regulated). Social function / “public service” (provides accessibility and social equity). Limited relationships with economic activities. Urban Transport: Assets versus Liabilities
Globalization, Commodification and Urbanization • Longer supply chains • International division of the production. • Fragmentation of production, distribution and consumption. • International trade • Imbalanced freight flows. • Higher levels of consumption • Growing incomes (challenged) • Debt and equity extraction.

City Logistics and Urban Freight Distribution • City Logistics • Relatively new field. • “The process for totally optimizing the logistics and transport activities by private companies in urban areas while considering the traffic environment, the traffic congestion and energy consumption within the framework of a market economy.” • Means to achieve freight distribution in urban areas. • Improve: • Efficiency of urban freight transportation. • Reduce traffic congestion. • Mitigate environmental impacts.

Freight Corridors & Freight Clusters • Geographical consequences • Migrating to more affordable locations in the periphery. • Growth in tons-km. • Competition between passengers (commuters) and freight traffic. • Freight corridors • Expands the sphere of distribution. • Providing an axis along which distribution centers can reliably service many locations along the corridor. • Emergence of freight clusters • Functionally unrelated distribution facilities. • Often located in small intermediary locations.

The “Last Mile” Urban Transport Problem • The “last mile” problem • Common issue in logistics. • More time-based than cost-based problem. • Components: • Delivery time (e.g. duration, possibility to fix delivery date); • Reliability of delivery (e.g. availability of goods, order handling time); • Flexibility of delivery (e.g. delivery date, delivery address); • Quality of delivery (e.g. accurate delivery, condition of delivered goods). • Unattended delivery problem: • Mainly apply to parcel deliveries. • Contradiction between working schedules and delivery schedules. • Made worse by the growth of two income families.

Challenges to Urban Freight Distribution • Multimodal Integration of Freight Transportation • Problem of modal dependence (80% trucking). • Specialization of modes, modal shift and freight diversion. • Entropy and Energy • Maintaining the cohesion and productivity of freight distribution. • Growing disorder and energy costs. • Urban/Suburban Supply Chains • Coping with the “last mile”. • Difficulties to maintain just-in-time and timely supply. • High distribution costs. • Adaptation of modes and delivery times.
