Emerging technologies offer transit agencies an opportunity to transform fundamental aspects of their operations and the way they communicate with their riders.  With nearly ubiquitous smartphones and social media tools among growing ridership patterns, transit providers can use aggregate mobile phone data and social media posts to improve system management.

Data-based reports can reach the operations center faster than field personnel, with mobile phone networks indicating station crowding or a passenger posting a photo of another pulling the emergency brake. Exceeding traditional reporting mechanisms (exclusive information from personnel) would save time and lower the costs of field monitoring while raising the trust between transit agencies and their customers.

By employing “co-monitoring” - the monitoring of field conditions through a combination of staff reports, data analysis and public observations – transit agencies will save time and costs for information gathering, improve their responsiveness, and establish working partnerships between the agencies and their customers. This report proposes a framework for a co-monitoring system, and discusses the expected benefits and challenges, as well as policy recommendations for agencies pursuing co-monitoring systems. Keys to successful co-monitoring systems are agency openness to new streams of data and respectful dialogue from both management and riders. Well-designed co-monitoring tools will put transit on track to manage smarter, more versatile transit systems for the twenty-first century.

This research explores the recent practice of connecting on-site carsharing service with off-street parking standards in multifamily developments; the San Francisco Bay Area, California, is used as a case study. If implemented well, such a policy could help boost the carsharing industry and reduce off-street parking, which is often criticized as being oversupplied as a result of excessive off-street parking standards. In 2011, the authors surveyed all carsharing sites in the Bay Area and all new residential developments (completed after 2000) with on-site carsharing spaces. The results showed that a significant number of carsharing spaces were located on residential properties, but 70% of the spaces had been retrofitted into existing buildings. For the new developments, on-site carsharing did not result in a reduction in the amount of regular off-street parking. Interviews with 15 professionals from three stakeholder groups (planners, developers, and service providers) revealed that even though all the stakeholders were in favor of on-site carsharing at residential developments, three major barriers existed: a lack of incentives, the complexity of access design, and high transaction costs.

Street standards as parking policy: rethinking the provision of residential street parking in American suburbs

This paper examines the parking mandate in residential street standards in the U.S. Based on literature review and a national survey of 97 principal cities in the top 52 metro areas, it reveals two unjustified assumptions behind the mandate: traffic lanes must maintain the continuous alignment even with limited, slow traffic and parking demand must be satisfied with dedicated parking lanes in absence of price. The mandate is likely to force market to over-supply parking and under-supply housing. The paper calls for the removal of the parking mandate from street standards, and the deregulation of the residential street parking market.

Timely updates, increased citizen engagement, and more effective marketing are just a few of the reasons transportation agencies have already started to adopt social media networking tools. Best Practices for Transportation Agency Use of Social Media offers real-world advice for planning and implementing social media from leading government practitioners, academic researchers, and industry experts.

The book provides an overview of the various social media platforms and tools, with examples of how transportation organizations use each platform. It contains a series of interviews that illustrate what creative agencies are doing to improve service, provide real-time updates, garner valuable information from their customers, and better serve their communities. It reveals powerful lessons learned from various transportation agencies, including a regional airport, city and state departments of transportation, and municipal transit agencies. 

Filled with examples from transportation organizations, the text provides ideas that can apply to all modes of transportation including mass transit, highways, aviation, ferries, bicycling, and walking. It describes how to measure the impact of your social media presence and also examines advanced uses of social media for obtaining information by involving customers and analyzing their social media use. 

The book outlines all the resources you will need to maintain a social media presence and describes how to use social media analytical tools to assess service strengths and weaknesses and customer sentiment. Explaining how to overcome the digital divide, language barriers, and accessibility challenges for patrons with disabilities, it provides you with the understanding of the various social media technologies along with the knowhow to determine which one is best for a specific situation and purpose.

 
 

Curb Parking Pricing for Local Residents: An Exploration in New York City Based on Willingness to Pay

Curb Parking Pricing for Local Residents: An Exploration in New York City Based on Willingness to Pay
Transport Policy

This paper investigates the feasibility of charging residents for on-street parking in dense urban neighborhoods as a way to clear parking supply and demand. We elicited residents’ willingness to pay (WTP) for a hypothetical parking permit program in New York City using a payment card approach, and estimate the key determinants through a Double Hurdle model. A little more than half of respondents (52.5%) are willing to pay for an average $408 per year, even though the revenue is not specified to be return back to the neighborhoods. Pricing becomes more acceptable in neighborhoods where the major parking problem is shortage and crowding caused mainly by local residents instead of parking intrusion by non-residents. The WTP value varies by resident car ownership and home parking types. The results suggest that curb parking pricing for local residents might be both economically and politically feasible in certain dense urban neighborhoods.

Home parking convenience, household car usage, and implications to residential parking policies

This paper investigates the effect of home parking convenience on households' car usage, and the implications to residential parking policies. A random sample of 840 households is selected from a travel survey in the New York City region, and their home parking types are identified through Google Street View. It found that with the same car ownership level, households without off-street parking used cars much less, and relied more on alternative modes than those with off-street parking. For households with access to both garage and street parking, those who use the handy street parking tend to make more car tours than those who do not. In general, convenient home parking encourages households' car usage. Policy implications to the minimum off-street parking requirement, residents parking permit, street cleaning, and new urbanism neighborhood design are discussed.

Residential Street Parking and Car Ownership

Residential Street Parking and Car Ownership

Problem, research strategy, and findings: Local governments’ minimum street-width standards may force developers to oversupply, and residents to pay excessively for, on-street parking in residential neighborhoods. Such oversupply is often presumed to both encourage car ownership and reduce housing affordability, although little useful evidence exists either way. This article examines the impact of street-parking supply on the car ownership of households with off-street parking in the New York City area.

The off- and on-street parking supply for each household was measured through Google Street View and Bing Maps. The impact of on-street parking on car ownership levels was then estimated in an innovative multivariate model. The unique set-up of the case study ensures 1) the weak endogeneity between parking supply and car ownership and 2) the low correlation between off-street and on-street parking supply, two major methodological challenges of the study. Results show that free residential street parking increases private car ownership by nearly 9%; that is, the availability of free street parking explains 1 out of 11 cars owned by households with off-street parking.

Takeaway for practice: These results offer support for community street standards that make on-street parking supply optional. They also suggest the merits of leaving the decisions of whether, and how many, on-street parking spaces to provide in new residential developments to private markets rather than regulations.

Research support: This project was supported by grants from the University Transportation Research Center (Region 2) and the Wagner School Faculty Research Fund.

From minimum to maximum: The impact of parking standard reform on residential parking supply in London

From minimum to maximum: The impact of parking standard reform on residential parking supply in London

This research examines residential parking supply in London before and after the minimum off-street parking standard was replaced by a maximum one in 2004. Based on 11 428 residential developments after and 216 developments before the reform, it is found that parking supply was reduced by approximately 40 per cent. Ninety-eight per cent was caused by the removal of the minimum standard, while only 2 per cent was due the imposition of the maximum standard. However, the parking supply is actually higher in areas with the highest density and the best transit service than in the areas immediately outside; the adopted maximum standard follows a similar pattern. The market-oriented approach to parking regulation can reduce excessive parking, but it depends on the particular sub-markets. Complementary policies such as strict parking maxima, on-street parking controls and parking taxes are often necessary to form an efficient parking market.

This article explores the concept of “public commons” and its relationship with travel decisions under a unique setting: street cleaning in the New York City area. Using a natural experimental design, it investigates the impact of street cleaning on car usage for five hundred randomly selected households. Street cleaning encourages car usage for households without off-street parking and discourages car usage for households with off-street parking. The net effect is an increase of vehicle miles traveled by 7.1 percent, at least 27 percent of which is not a mere redistribution from non-street-cleaning days.
