Active mode (walking, bicycling, and their variants) users are exposed to various negative externalities from motor vehicle traffic, including injury risks, noise, and air pollutants. This directly harms the users of these modes and discourages their use, creating a self-reinforcing cycle of less active travel, more motorized travel, and more harmful effects. These impacts are widely recognized but seldom quantified. This study evaluates these impacts and their consequences by measuring the additional distances that bicyclists travel in order to avoid roads with heavy motor vehicle traffic, based on a sample of German-Austrian bicycle organization members (n = 491), and monetizes the incremental costs. The results indicate that survey respondents cycle an average 6.4% longer distances to avoid traffic impacts, including injury risks, air, and noise pollution. Using standard monetization methods, these detours are estimated to impose private costs of at least €0.24/cycle-km, plus increased external costs when travellers shift from non-motorized to motorized modes. Conventional transport planning tends to overlook these impacts, resulting in overinvestment in roadway expansions and underinvestments in other types of transport improvements, including sidewalks, crosswalks, bikelanes, paths, traffic calming, and speed reductions. These insights should have importance for transport planning and economics.
Making accurate world maps is mathematically impossible.
There are at least 7,102 known languages alive in the world today. Twenty-three of these languages are a mother tongue for more than 50 million people. The 23 languages make up the native tongue of 4.1 billion people. We represent each language within black borders and then provide the numbers of native speakers (in millions) by country. The colour of these countries shows how languages have taken root in many different regions.
From Paris to New York, we’ve matched metro maps against versions that only include fully accessible stations. The results are discouraging – but are any cities doing it right?
‘Transportation diversity’ refers to the variety of mobility and accessibility options available in a particular situation, including various modes, services and destinations. A transport system must be diverse in order to serve diverse demands, including the needs of people who cannot, should not or prefer not to drive. Multimodal planning that increases transport system diversity tends to increase efficiency, equity and resilience, and achieves specific planning goals. Conventional planning undervalues many of these benefits, resulting in less diverse, more automobile-dependent transport systems than optimal to serve user needs and achieve planning goals. This report examines consumer demands for various travel options, transport diversity benefits, and methods for evaluating optimal transport system diversity.

A French project to develop a concept for freight operations on light rail networks reached a milestone on the morning of June 13, when a tram was used to deliver merchandise to a retailer in St Etienne.
The trial delivery to the Casino store in Place Carnot was organised as part of the TramFret project, an initiative led by research and development institute Efficacity, which is being supported by St Etienne public transport operator Stas.
Special authorisation was granted for the trial by STRMTG, the national agency responsible for tramway safety.
TramFret says the trial will enable it to optimise the system, begin industrial development of the concept, and study its sustainability.
If the first phase of the trial is successful further testing will be carried out in St Etienne in the coming weeks.
Norway will ban the sale of all fossil fuel-based cars in the next decade, continuing its trend towards becoming one of the most ecologically progressive countries on the planet, according to reports.
Large cities of the world require strong coverage of rapid transit networks to ensure they remain competitive, and that local communities have a healthy environment, vibrant urban economy, and an equitable, high quality of life for all residents. Many cities—especially those with growing populations, incomes, and/or large infrastructure deficits—have not, however, built rapid transit at the scale and rate needed to meet mobility needs. This paper is Part 2 in a series of research papers that explores how countries can grow their rapid transit infrastructure. This Part focuses on the role that funding, financing, and capacity have played in delivering rapid transit infrastructure in nine countries.
Part 1, Evaluating Country Performance in Meeting the Transit Needs of Urban Populations, released in May 2014, drew upon a comprehensive global data set developed by ITDP of rapid transit infrastructure to create a comparative analysis of rapid transit infrastructure in nine countries that are major contributors to greenhouse gas emissions.
Part 2, Growing Rapid Transit Infrastructure: Funding, Financing, and Capacity, analyzes how the funding practices, financing practices, and institutional capacity impact a country’s ability to deliver rapid transit effectively.
Shiny green and white articulated buses glide in and out of sleek stations that protect riders from the elements. Level boarding, simple off and on-board payment, ubiquitous display signs with real-time arrival information and cleanly designed system maps further ensure a comfortable and worry-free user experience. Enthusiastically received by the public, press and authorities, and with robust ridership levels, CTfastrak is a bold display of BRT’s potential to rapidly and radically upgrade transit in US cities.

Bus rapid transit has grown by 383 percent in the last ten years, according to new data released by ITDP. As cities around the world discover the benefits and cost effectiveness of BRT, they have built hundreds of systems across dozens of countries that qualify as true BRT. A new interactive map shows a comprehesive list of BRT systems globally, based on in depth data of systems scored in 2013 and 2014.

When we think of great cities for sustainable transport, we think of picturesque cities in Northern Europe, such as Copenhagen, or wealthy, dense enclaves such as Hong Kong or Singapore. There have, however, been exciting transformations in cities all over the world, particularly in the global south. Here are five cities that have improved quality of life for millions by investing in sustainable, equitable transport.

The goal of BRTData is to improve the sustainable transport community’s access to reliable and current data about the BRT and bus corridors currently in operation. We aim to improve the quality and impact of the industry by opening up access to data about the design, performance and cost of these systems. The platform provides a convenient repository of data from a variety of sources including researchers, transit agencies, municipalities and NGOs.

Parking is a mystery. Many public agencies push for more parking in buildings, but, rather than alleviating the parking problem, it leads to massive traffic jams, severe air pollution, and more road deaths. Under the illusion that density creates congestion, public agencies also control building density. However, it is parking, not density, that creates traffic congestion. Excessive parking supply that is cheap or free induces people to use personal motor vehicles—even when good public transport is provided.
Cities across the world are now realizing their past follies. They now follow a simple mantra— add transit, build density, cut parking. Put another way, where there is good connectivity to mass rapid transit, building density is welcome but parking supply is not. Parking fees are pegged to parking demand—when demand increases, fees also increases. Revenue generated this way is used to build complete streets—with better walking and cycling infrastructure—and expand public transport.
Parking Basics outlines these key principles and steps involved in managing on-street parking and regulating off-street parking.

This report describes a framework for determining when bus lanes are warranted. Bus lanes increase urban transport system efficiency and equity by favoring higher value trips and more space-efficient modes over lower-value trips and space-intensive modes. Bus lanes can carry more passengers than general traffic lanes, and so increase total capacity (people per traffic lane), increase transit system operating efficiency, directly benefit bus passengers, cause travelers to shift from automobile to transit which reduces various transportation problems, and support more transit-oriented development. This paper examines how these impacts are considered in conventional planning, describes examples of bus lane planning and evaluation, and discusses ways to optimize their implementation. This analysis suggests that bus lanes are generally warranted where, after all economically justified pro-transit policies are implemented, they would attract more than 800 peak-hour passengers (about 20 buses) on surface streets or 1,800 peak-hour passengers (about 40 buses) on grade-separated highways, since they carry more passengers than a general traffic lane, and so save total travel time. Bus lanes are often justified with even lower ridership levels, due to the additional indirect benefits provided by reduced urban-peak automobile travel. Comprehensive evaluation can justify extensive bus lane networks in most cities, particularly rapidly-growing cities in developing countries.
