The principles of public transport network planning: a review of the emerging literature with select examples
This paper highlights for urban planners the key strategies and tactics that can be deployed to improve suburban public transport networks.
Introduction
The governance and management of public transport systems is an essential component of metropolitan planning and urban management. Most metropolitan strategies in Australia and in other jurisdictions presuppose the provision of public transport. Yet there is often a disconnection between transport plans and land-use schemes. Similarly, metropolitan land-use plans that do integrate with transport plans tend to focus on infrastructure rather than service quality and connectivity. A failure to adequately consider the quality of public transport networks in land-use planning analysis has the potential to produce poor planning outcomes in two key ways. First new land-uses may be inadequately served with public transport services, leading to dependence on alternative travel modes, such as cars. Second, the failure to recognise the significance of well-planned local public transport networks may result in the preclusion of some land-use options. This preclusion may relate to the location of land-uses or their design, such as over-provision of carparking. The continuing debate over whether to address suburban cardependence via land-use change or via transport planning is a case in point. And while the arguments in favour of and against land-use change as a means to overcome car dependence are well known in the planning literature. There is a growing if not yet widely appreciated literature that advocates improvements to public transport network planning and coordination as a means of reducing car dependence. The recognition of improved public transport network planning as a means of reducing car dependence is immensely significant because it offers planners an additional or alternative tool for managing urban transport patterns beyond land-use variation or investment in heavy infrastructure.
Urban planning practitioners are not yet well served and informed by the broader public transport planning literature on the advantages of public transport network planning. While there is an extensive literature focusing on the economics and engineering of urban public transport systems the planning literature on the practices that contribute to success in public transport network design and operations is relatively poorly documented. There is also very little literature dedicated to public transport network design within Australian cities which are distinguished by highly centralised radial heavy rail networks with bus or tram networks that are well developed in inner urban zones but less so in the outer suburbs.
The remainder of this paper has four objectives for transport planning theory and practice. First the paper reviews the literature on public transport network planning principles; next the paper attempts to formulate these principles in practical terms such that they can be applied to line and network design; third the paper considers further dimensions of network planning, including institutional arrangements and transition points in network design. The paper is intended for three audiences. The first is planning scholars who are involved in debates about public transport. The second is strategic policy officials in planning agencies who are involved in the planning and design of public transport networks. The third audience comprises those involved in development processes and who seek insights into the technical components of public transport network planning.
Some caveats are appropriate however. The paper is not seeking to justify public transport network planning. The authors consider that the case for dedicated planning is implicit in the assumption that cities should provide good quality public transport to their residents. The wider case in favour of network planning has been successfully advanced elsewhere. Conversely, the paper is not intended as a directly applicable manual of detailed transport planning practice. While it does offer some insights into the practical public transport network planning task such guidance is better provided by Nielsen et al and Vuchic. Instead the paper highlights for urban planners the key strategies and tactics for that can be deployed to improve suburban public transport networks. Understanding these principles should thus assist urban planners â and urban scholars â to better shape and evaluate urban development processes and patterns
Examination of Regional Transit Service Under Contracting: A Case Study in the Greater New Orleans Region, Research Report 10-09
Many local governments and transit agencies in the United States face financial difficulties in providing adequate public transit service in individual systems, and in providing sufficient regional coordination to accommodate transit trips involving at least one transfer between systems. These difficulties can be attributed to the recent economic downturn, continuing withdrawal of the state and federal funds that help support local transit service, a decline in local funding for transit service in inner cities due to ongoing suburbanization, and a distribution of resources that responds to geographic equity without addressing service needs. This study examines two main research questions: (1) the effect of a âdelegated managementâ contract on efficiency and effectiveness within a single transit system, and (2) the effects of a single private firmâcontracted separately by more than one agency in the same regionâon regional coordination, exploring the case in Greater New Orleans. The current situation in New Orleans exhibits two unique transit service conditions. First, New Orleans Regional Transit Authority (RTA) executed a âdelegated managementâ contract with a multinational private firm, outsourcing more functions (e.g., management, planning, funding) to the contractor than has been typical in the U.S. Second, as the same contractor has also been contracted by another transit agency in an adjacent jurisdictionâJefferson Transit (JeT), this firm may potentially have economic incentives to improve regional coordination, in order to increase the productivity and effectiveness of its own transit service provision. Although the limited amount of available operation and financial data has prevented us from drawing more definitive conclusions, the findings of this multifaceted study should provide valuable information on a transit service contracting approach new to the U.S.: delegated management. This study also identified a coherent set of indices with which to evaluate the regional coordination of transit service, the present status of coordination among U.S. transit agencies, and barriers that need to be resolved for regional transit coordination to be successful

Transportation network companies as cost reduction strategies for paratransit
Paratransit service is an auxiliary type of public transportation provided for people with disabilities and older adults. Federal ADA regulations require all transit agencies receiving federal funding to provide paratransit service, but the per trip cost to transit operators is extremely expensive. Many transit agencies are looking for ways to reduce costs without limiting services. For many agencies, this results in providing the minimum services as required by ADA regulations. However, Bostonâs Massachusetts Bay Transit Authority (MBTA) has taken a different approach to cost reduction by entering into one of the first partnerships with transportation network companies. In September 2016, MBTAâs paratransit service, The Ride, began a partnership with both Uber and Lyft as a cost reduction strategy for paratransit provision. Since the beginning of the partnership, MBTA has been able to reduce costs of providing paratransit while maintaining the same level of service. This report will examine the benefits and limitations of such partnerships between transit agencies and transportation network companies, using MBTAâs The Ride partnership as an example for potentially successful partnerships throughout the United States.Community and Regional Plannin
Making meaningful comparisons between road and rail â substituting average energy consumption data for rail with empirical analysis
Within the transport sector, modal shift towards more efficient and less polluting modes could be a key policy goal to help meet targets to reduce energy consumption and carbon emissions. However, making comparisons between modes is not necessarily straightforward. Average energy and emissions data are often relied upon, particularly for, rail, which may not be applicable to a given context. Some UK train operating companies have recently fitted electricity metres to their trains, from which energy consumption data have been obtained. This has enabled an understanding to be gained of how energy consumption and related emissions are affected by a number of factors, including train and service type. Comparisons are made with existing data for road and rail. It is noted that although more specific data can be useful in informing policy and making some decisions, average data continue to play an important role when considering the overall picture

Governance in niche development for a transition to a new mobility regime
Urban mobility is a difficult sustainability challenge; measures to reduce transport impacts produce only marginal reductions in overall energy use and CO2 emissions. Even fuel switch to electric vehicles and measures to manage traffic produce insufficient improvements. Seeking transport sustainability within the existing socio-technical regime involves policy approaches for dense cities to provide high-capacity, corridor-based public transport, expecting people to arrange their lives around such transport systems. Yet this socio-technical regime ill-fits modern mobility needs.
The reluctance to use public transport stems much from this 150 year old regime configuration. The social-technical landscape has shifted significantly: travel patterns are increasingly dispersed in space and time â not funnelled into traditional corridor peak-hour movements. The key is not getting people to return to travel patterns of 100 years ago, but in a transition to a socio-technical transport regime that delivers sustainability compatible with the 21st century social-technical landscape.
An opportunity may be emerging for socio-technical configurations in niche environments to effect transitions to alternate mobility futures. Autonomous vehicles are rapidly approaching market application. Since 2011, small autonomous pods have operated on segregated tracks at Heathrow Airport. In 2014 a similar system opened at the Suncheon Bay tourist area in South Korea.
Since 2011 there have been public street trials of autonomous vehicles in the USA and in 2015 they became street legal in the UK. The Milton Keynes (MK) âPathfinderâ project focuses on two-seat pods which do not need segregated tracks, but will run on cycleways and footpaths, mixing with cyclists and pedestrians. Trials will start in 2015, on short distance links from the railway station to destinations in Central Milton Keynes. This project forms part of the wider Milton Keynes Future Cities Programme and Open University-led MK:Smart project.
This paper draws on these trials in MK to show through case study research how autonomous vehicles applications are moving beyond protected niches and, along with other developments, hold the potential to stimulate a major transition in public transport systems. The vehicles are small and each journey is individual to the passenger(s). Services do not run along corridor routes, like buses and trams, but are based on alternate rule-sets to the existing regime with individual journeys customised for each user. Such developments may therefore stimulate transition to totally different sorts of public transport systems and ultimately, socio-technical mobility regimes, by offering much more to users than any corridor system can provide. Rather than people adjusting their behaviour to bus routes, schedules and operating times, they travel directly, whenever they want, on services running 24/7. Thus these new regimes could be more compatible with lifestyle and economic trends that comprise 21st century socio-technical landscapes. As such, they provide credible alternatives to the private car, and so hold potential to deliver major sustainability gains.
But such transitions face major challenges from entrenched actors within the existing regime. Taxis, minicabs and bus operators would be threatened. If the Uber cab app is being blocked by incumbent actors, they look likely to be powerful opponents of autonomous vehicle based cab services. However, MK provides an interesting innovation context where there are several overlapping smart transport niches in different stages of development. As well as autonomous pods, demand responsive minibuses are planned and inductive changed electric buses are in service. If these projects build links to each other (niche accumulation), demonstrate economic value and reproduced beyond their original experimental spaces (niche proliferation), there is potential for them to overcome incumbent resistance. In Milton Keynes, these processes could be getting close to reaching critical mass, opening up the possibility of moving closer to radical regime transitions
