Urban freight distribution

Last updated

Urban freight distribution is the system and process by which goods are collected, transported, and distributed within urban environments. The urban freight system can include seaports, airports, [1] manufacturing facilities, and warehouse/distribution centers that are connected by a network of railroads, rail yards, pipelines, highways, and roadways that enable goods to get to their destinations.

Urban freight distribution is essential to supporting international and domestic trade as well as the daily needs of local businesses and consumers. In addition, it provides thousands of jobs and other economic benefits. However, a number of challenges are associated with urban freight, such as road congestion, environmental impacts, and land use conflicts due to the proximity of freight facilities and vehicles to residential and sensitive land uses. As urban freight continues to grow, the community and environmental impacts associated with these challenges will need to be addressed and mitigated.

Description and evolution

One of the main drivers of urban freight transport has been the continued urbanization of the world's population. According to the United Nations (UN), 3.9 billion people (54%) of the world's population lives in urban areas, up from 746 million in 1950. Projections indicate that urbanization combined with the overall growth of the world's population could add another 2.5 billion people to urban populations by 2050, or 66% of the total world population. The UN notes that the number of mega-cities of ten million or more inhabitants has increased from ten in 1990 to 28 in 2014. By 2030, the world is expected to have 41 mega-cities. [2]

As the total number and concentration of the world's population in urban areas has grown, so has the importance of transporting and delivering the consumer goods required to sustain these urban areas. This includes freight transportation to and from warehouse/distribution centers, retail stores, businesses, and homes.

Urban freight distribution also involves transportation from freight-generating facilities such as seaports, airports, railyards, manufacturing facilities, and warehouse/distribution centers, many of which are located in urban areas and utilize an urban region's roadway and railway network to transport goods. In addition, many companies today use sophisticated computerized logistics systems to manage their supply chains and employ just-in-time (JIT) manufacturing and delivery to minimize inventory and expenses. While JIT can significantly reduce production costs, it also requires efficient and reliable transportation systems, both within and between urban regions, to be effective.

At the local or neighborhood level, the growth of E-commerce and small package delivery by firms such as FedEx and UPS means that cities and communities should consider the needs of truck circulation and parking/loading zones within residential and commercial areas to facilitate delivery of goods.

Complicating urban freight is the need of the transportation system to also accommodate other roadway users such as automobiles, public transit, bicycles, and pedestrians. For example, cities are increasingly implementing road diets to enhance and encourage walking, bicycling, livability, and pedestrian safety. According to the Federal Highway Administration (FHWA), it is possible for road diets to accommodate freight movement if factors such as current land use, truck size, delivery parking areas, and intersection design are considered in the planning process. [3]

Components

Urban freight distribution can include the following components, depending on the location of the urban area:

Seaports

Seaports allow ships to dock and transfer people or cargo to or from land. Seaports handle a variety of goods including cargo shipped by intermodal containers, bulk commodities such as crude oil, and specialized cargo such as automobiles. Major container ports in North America include the Port of Los Angeles, Port of Long Beach, Port of New York and New Jersey, Port of Savannah, Port of Vancouver, Port of Oakland, Port of Virginia, Port of Houston, Port of Tacoma, Port of Charleston, and Port of Seattle.

Airports

Airports, and more specifically air cargo, are a significant component of the freight system. It is estimated that in the United States in 2013, over $1.1 billion worth of goods traveled by air. [4] The top five airports in the U.S., ranked by landed weight of all-cargo operations in 2014, are Memphis International Airport, Ted Stevens Anchorage International Airport, Louisville International Airport, Chicago O'Hare International Airport, and Miami International Airport. [4]

Warehouses and distribution centers

A distribution center is a warehouse or other specialized building that receives, stores, and distributes goods to a variety of destinations such as retail stores, businesses, consumers, manufacturing facilities, or other distribution centers.

Railways and railyards

Railroads haul a variety of goods such as intermodal containers, bulk goods, and other specialized cargo such as automobiles. In the United States, railroads are most commonly used to transport cargo over distances of 1,000 to 2,000 miles. Railroads are complemented by rail yards that allow freight from shippers to be trucked in, transferred onto railcars, and for trains to be assembled. There are three railroad classes in the United States: Class I, II, and III. According to the Association of American Railroads, Class I railroads had a minimum carrier operating revenue of $433.2 million in 2011. [1] There are six Class I railroads in the United States: BNSF Railway, Canadian National Railway, Canadian Pacific Kansas City, CSX Transportation, Norfolk Southern Railway, and Union Pacific Railroad.

Roads

In the United States, trucks transport the vast majority of goods in terms of both weight and value. In fact, trucks transport 85% of goods traveling 249 miles or less. [4] To transport their goods, trucks utilize the roadway network consisting of freeways, highways, and arterials.

The roads that trucks can travel on are regulated at the national, state, and local levels. In the United States the Surface Transportation Assistance Act of 1982 established a National Network of highways that permits "conventional combination" trucks (tractors with one semitrailer up to 48 feet in length or with one 28-foot semitrailer and one 28-foot trailer, and can be up to 102 inches wide) to travel on. [5] The National Network consists of the Interstate Highway System as well as non-interstate highways designated by states. The FHWA also designates intermodal connectors and the National Highway Freight Network, which consists of the Primary Highway Freight System (PHFS), portions of the interstate system not part of the PHFS, Critical Rural Freight Corridors (CRFC), and Critical Urban Freight Corridors (CUFC). [6]

At the local level, many cities designate truck routes within their respective jurisdictions. In most jurisdictions, trucks are allowed to use most streets as needed for local deliveries. However, local jurisdictions can restrict "through" truck trips that pass through a jurisdiction but do not end or begin there. For these "through" truck trips, trucks can be required to travel on designated truck routes and remain on the designated truck route for as long of the trip as possible.

Designated truck routes enable cities to channelize trucks onto roadways that have sufficient lane and intersection width, and in some cases pavement strength, to accommodate trucks. In addition, designated truck routes can be used to direct trucks onto arterials in industrial and commercial areas and away from residential areas, schools, parks, and other sensitive land uses. [7]

Many local jurisdictions also designate curbside truck parking and loading zones. The purpose of truck parking and loading zones is to provide adequate space for trucks to load and unload their goods, and prevent illegal and double parking by trucks. Cities provide guidelines for locating parking and loading zones and often allow businesses to apply to establish a new parking and loading zone. Cities can also regulate the type of truck and length of time that trucks can park in a parking or loading zone and establish fines for violations.

Benefits

The efficient and timely distribution of freight is critical for supporting the demands of modern urban areas. Without freight distribution, urban areas could not survive, grow, and flourish.

Freight distribution also generates significant economic benefits. For example, the Bureau of Transportation Statistics (BTS) estimates that in 2012, the freight industry (defined as rail, water, truck, and pipeline transportation, support activities for transportation, couriers and messengers, and warehousing and storage) employed over 4.3 million people and paid total wages of almost $184 billion, for an average wage of over $42,000US annually. [4] Furthermore, for-hire transportation services contributed $481 billion to U.S. gross domestic product in 2013. [4]

Challenges

There are a number of challenges resulting from urban freight distribution, including traffic congestion, environmental impacts, and land use conflicts.

These issues affect not only the efficiency of freight distribution but also the quality of life of citizens and public health.

Policy and planning

In the United States, urban freight policy and planning is conducted at the federal, state, regional, and local levels. At the federal level, freight planning and policy is guided by the Fixing America's Surface Transportation Act (FAST) that establishes the National Multimodal Freight Policy and National Freight Strategic Plan. [12] In addition, the FHWA Office of Freight Management and Operations conducts freight research, develops analytical tools and data, and organizes freight professional development programs. [13]

At the state level, state Departments of Transportation (DOTs) are primarily responsible for planning, designing, constructing, and maintaining the highway system within the state. As part of the FAST Act, states were given additional roles and responsibilities for freight planning. States are now required to establish a State freight advisory committee as well as develop a comprehensive State freight plan. [12]

Freight planning at the regional level is conducted by Metropolitan Planning Organizations (MPOs). MPOs are required in urbanized areas with a population greater than 50,000 and are mandated by the federal government to develop plans for transportation, growth management, hazardous waste management and air quality. An MPO must have a "continuing, cooperative and comprehensive" (3C) transportation planning process that results in plans and programs consistent with the comprehensively planned development of its corresponding urbanized area. The two primary roles of an MPO are to prepare the Regional Transportation Plan (RTP) and Transportation Improvement Program (TIP). The RTP presents a 20-year transportation vision for the region and provides a long-term investment framework for addressing the region's transportation and related challenges. The RTP addresses all modes of transportation including highway and transit projects, as well as high-speed regional transport. Projects must be included in the RTP to be eligible for state and federal funding. The TIP is a listing of proposed transportation projects to be funded through a variety of federal, state and local sources over the next six years in the respective region. [14] In addition, some MPOs convene freight advisory committees that bring together public and private sector representatives to plan for freight in the region. One example is the Delaware Valley Regional Planning Commission Goods Movement Task Force. [15]

Counties and local cities are primarily responsible for design, construction, and maintenance of the local roadway network within a county or city. This includes capacity enhancements, pavement maintenance, sidewalks, street lighting, signals, and signage. From a freight perspective, cities also designate local truck routes, Surface Transportation Assistance Act (STAA) terminal access routes, and parking and loading zones. In some cases, counties also collect and allocate locally generated tax revenue for transportation projects.

Strategies

A variety of strategies exist and have been proposed or implemented by governments and private industry that help address the challenges of urban freight distribution. The range of strategies includes infrastructure, operational, technological, and policy:

Infrastructure

Policy

Land use/facility design

Refrigerated freight

Consumers enjoy a best quality of life due to economic and societal changes, which imply several modifications in consumption. In fact, they can afford to consume more perishable products for example. Apart from that, the government has developed policies of "security of quality" and the regulation, obligating to add new products that need to be transported in refrigerated vehicles to the existing list. It is also obligatory to control the temperature of those vehicles during the delivery. Societal and legal requirements have obliged suppliers and transport companies to resort more frequently to the refrigerated urban freight distribution.

The use of refrigerated transportation improved the quality of the service provided but it also implies high negative impacts for the urban environment and citizens' quality of life. The traditional system of refrigeration consumes more combustible, so it increases the CO2 emissions. Noise due to the refrigeration system and the type of combustible used can also be a problem in urban zones. [18]

Technology used

Most of the food that needs to be refrigerated is transported by road through the use of vehicles equipped with an isolated structure.

Many factors are evaluated during the design of the units for refrigerated food transportation, for example:

The refrigeration system used to transport food is based on vapor compression that ensures the maintenance of certain conditions such as temperature in function of the quantity and type of food transported. The units that use this technique can work at full thus allowing controlled transport of refrigerated loads.

Energy consumption and environmental impact

The energetic efficiency of the refrigerated boxes of the modes of transport has more importance depending on the region of the world. The rise in combustible prices and the environment evolution are other aspects that companies need to take into account.

The combustible consumption depends on the refrigerated system which has to be in relation with the kind of goods transported (refrigerated products as fruit and vegetables can travel at a 0 °C temperature and frozen products need a temperature lower than 20 °C).

The contamination is due to a combination of factors such as the pattern use of the refrigeration system, the type of product transported, the exposition to the sun, the density of the refrigerant, the setting of the control system such as modulation and the activation/deactivation of the compressor.

In some cases, energy consumption for the distribution of fresh food can be higher than for the transportation of frozen food, because of stricter controls in terms of product and because it breath more air to keep the uniform temperature during the distribution.

Transport through a passive-cooling system

According to a study (A. Ghirardi, 2003), the exportation and the distribution of fruit and vegetables are affected by the high cost of the environmental impact. The systems and technologies currently used are expensive, not compatible with the environment and not sustainable.

The transit time is a central aspect in export operations, and it has to take into account multiple factors, even imponderable as the quality of the product at destination. The passive refrigeration system allow to solve the problem of quality preserving, making the time of surrender compatible with the combined transport and independent of the energy source during the running, allowing also the use modes of transport without electrical connection.

An examination of the critical factors of refrigerated transport and characteristics of the passive refrigeration system emerges a synergy capable of solving the key aspects, and in particular:

For distribution in urban areas, the saturation of the traffic and the propensity of cities to limit the flow of vehicles for goods distribution require the optimization of the logistics and distribution chain. This optimization is realizable by employing passive-cooling container units that are independent of loading and transport and allow the use of the same mode, also non-refrigerated, for the distribution using only one mode to deliver its order to the stores, keeping the products at an optimum temperatures and consistent with autonomy.

The vast majority of passenger travel in the United States occurs by automobile for shorter distances and airplane or railroad for longer distances. Most cargo in the U.S. is transported by, in descending order, railroad, truck, pipeline, or boat; air shipping is typically used only for perishables and premium express shipments. Transportation is the largest source of greenhouse gas emissions in the United States.

<span class="mw-page-title-main">Road transport</span> Collective term for all forms of transport which takes place on roads

Road transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries. Movement along roads may be by bike, automobile, bus, truck, or by animal such as horse or oxen. Standard networks of roads were adopted by Romans, Persians, Aztec, and other early empires, and may be regarded as a feature of empires. Cargo may be transported by trucking companies, while passengers may be transported via mass transit. Commonly defined features of modern roads include defined lanes and signage. Various classes of road exist, from two-lane local roads with at-grade intersections to controlled-access highways with all cross traffic grade-separated.

The resources managed in logistics may include tangible goods such as materials, equipment, and supplies, as well as food and other consumable items.

<span class="mw-page-title-main">Traffic congestion</span> Transport condition characterized by slower speed and high density

Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads.

A warehouse is a building for storing goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial parks on the outskirts of cities, towns, or villages.

<span class="mw-page-title-main">Distribution center</span> Building stocked with goods for delivery

A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a "retail distribution center" normally distributes goods to retail stores, an "order fulfillment center" commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.

<span class="mw-page-title-main">Rail freight transport</span> Practice of transporting cargo by rail

Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers.

Truckload shipping is the movement of large amounts of homogeneous cargo, generally the amount necessary to fill an entire semi-trailer or intermodal container. A truckload carrier is a trucking company that generally contracts an entire trailer-load to a single customer. This is as opposed to a less-than truckload (LTL) company that generally mixes freight from several customers in each trailer. One advantage Full Truckload (FTL) carriers have over Less than Truckload carriers is that the freight is never handled en route, whereas an LTL shipment will typically be transported on several different trailers. Truckload shipments are typically run on 48' or 53'dry van trailers which will hold 24 or 26 pallets respectively.

<span class="mw-page-title-main">Cold chain</span> Low-temperature supply chain

Cold chain is a set of rules and procedures that ensure the systematic coordination of activities for ensuring temperature-control of goods while in storage and transit. The objective of a cold chain is to preserve the integrity and quality of goods such as pharmaceutical products or perishable good from production to consumption. Cold chain management earned its name as a "chain" because it involves linking a set of storage locations and special transport equipment, required for ensuring that temperature conditions for goods are met, while they are in storage or in transit from production to consumption, akin to the interconnected links of a physical chain.

<span class="mw-page-title-main">Land transport</span> Mode of transport

Land transport is the transport or movement of people, animals or goods from one location to another location on land. This is in contrast with other main types of transport such as maritime transport and aviation. The two main forms of land transport can be considered to be rail transport and road transport.

A specialized set of jargon describe the tools, equipment, and employment sectors used in the trucking industry in the United States. Some terms may be used within other English-speaking countries, or within the freight industry in general. For example, shore power is a term borrowed from shipping terminology, in which electrical power is transferred from shore to ship, instead of the ship relying upon idling its engines. Drawing power from land lines is more efficient than engine idling and eliminates localized air pollution. Another borrowed term is "landing gear", which refers to the legs which support the front end of a semi-trailer when it is not connected to a semi-truck. Some nicknames are obvious wordplay, such as "portable parking lot", in reference to a truck that carries automobiles.

<span class="mw-page-title-main">American Trucking Associations</span>

The American Trucking Associations (ATA), founded in 1933, is the largest national trade association for the trucking industry. ATA represents more than 37,000 members covering every type of motor carrier in the United States through a federation of other trucking groups, industry-related conferences, and its 50 affiliated state trucking associations. Former Governor of Kansas Bill Graves was replaced by Chris Spear as the ATA's president and CEO in July 2016.

Transport or transportation is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land, water, cable, pipelines, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations.

Traffic simulation or the simulation of transportation systems is the mathematical modeling of transportation systems through the application of computer software to better help plan, design, and operate transportation systems. Simulation of transportation systems started in the 1950s, and is an important area of discipline in traffic engineering and transportation planning today. Various national and local transportation agencies, academic institutions and consulting firms use simulation to aid in their management of transportation networks.

<span class="mw-page-title-main">Last mile (transportation)</span> Last leg of the movement of people or goods from hubs

In supply chain management and transportation planning, the last mile or last kilometer is the last leg of a journey comprising the movement of passengers and goods from a transportation hub to a final destination. The concept of "last mile" was adopted from the telecommunications industry, which faced difficulty connecting individual homes to the main telecommunications network. Similarly, in supply chain management, last-mile describes the logistical challenges at the last phase of transportation getting people and packages from hubs to their final destinations.

<span class="mw-page-title-main">Cikarang Dry Port</span> Port in Indonesia

Cikarang Dry Port (CDP) is a dry port in Kota Jababeka at Cikarang, West Java, Indonesia. With a total area of 200 hectares, CDP was founded in 2010. It is run as Indonesia's first and only Integrated Customs Services Zone by PT Cikarang Inland Port, a division of the publicly traded PT Jababeka Tbk. As an inland dry port model, CDP acts as a port extension that addresses ongoing traffic jams and delays at Tanjung Priok, a significant import/export gateway. Reducing the dwelling time from 3.2 days to the government-mandated 2.5 days is the primary goal.
