Abstract
Purpose
The purpose of this paper is to show the way in which State Transportation Agencies throughout the USA are under increasing pressure to preserve and expand the nation's roadway infrastructure in the shortest possible time with only a finite pool of resources with which to meet a state's transportation needs. With this in mind, a rapid construction methods decision‐making system was developed, to be used during the preliminary and conceptual design stage of a roadway project.
Design/methodology/approach
The research completed an extensive literature review and examined case studies to identify rapid construction methods and summarize valuable lessons learned. Designed for use by the Kentucky Transportation Cabinet, the research developed a series of conceptual road user cost (RUC) tables that reflect different socioeconomic conditions by varying the value of time based on average hourly per capita income and wages for different counties in Kentucky.
Findings
The case studies identified that the most effective mean for State Transportation Agencies to accelerate construction is through their construction contracts. Furthermore, determining RUC as outlined in the research way simplifies the method of calculating RUC by using fewer variables than would typically be available during the preliminary and conceptual design stage.
Research limitations/implications
The proposed decision‐making model is designed for State Transportation Agencies who are involved in the scenarios of determining the value of accelerating construction in both an urban and rural environments.
Practical implications
The project's intent in determining conceptual road user costs is to support a decision‐making process to identify the need and type of rapid construction methods for any given project.
Originality/value
A specific decision‐making process is proposed, and it uses the ratios of the Conceptual Road User Cost to the Maximum Allowable Road User Cost and a set of additional criteria based on project features to recommend a selection of rapid construction methods for a given highway project.

Abstract
Purpose
The publication presents an analysis of the cost and schedule performance of incentive/disincentive projects and case studies toward developing a systematic disincentive valuation process, with Construction Analysis for Pavement Rehabilitation Strategies (CA4PRS) software integration that aids agencies in minimizing the likelihood of court challenges of disincentives.
Design/methodology/approach
From a California transportation database, the authors performed cost and schedule analyses of 43 incentive/disincentive (I/D) projects and case studies on four of those I/D projects. Interviewees included subject matter experts from transportation organizations to ensure applicability and maximum value-adding, and the process was implemented on ten California transportation projects and monitored for performance.
Findings
The presented process mitigates the contractor's ability to claim disincentives as penalties in a court of law through the following: (1) all calculations are performed using project-specific bases, backed by estimations of actual incurred costs; (2) the CA4PRS software allows for estimation transparency and (3) the clarity of cost inclusions reduces any chances of “double-dipping” between disincentives and liquidated damages.
Practical implications
Transportation agencies have historically faced legal challenges to their enforcements of disincentives. As agencies continue to apply disincentives on more megaprojects, contractors will likely attempt to pursue legal challenges more frequently. The presented process mitigates the likelihood of these challenges going to court and increases the accuracy and efficiency of disincentives.
Originality/value
While there have been publications that discuss the legal challenges of imposing disincentives, they mainly provide guidelines and lack applicable processes. Existing literature that does present incentive/disincentive valuation process focuses on incentive valuations and neglects the disincentives' legal challenges. The following publication fills this gap by presenting an applicable disincentive valuation process for transportation projects which incorporates the guidelines for legal mitigation.

Abstract
Purpose
This study aims to explore the challenges of truck-sharing and effective ways of dealing with those in achieving supply chain collaboration and collaboration in transportation management (e.g. transport collaboration) for transport capacity expansion, and reducing carbon emission and traffic congestion for integrating environmental and social sustainability issues. This paper also reveals insights into successful shared-transportation and a reduction in empty trips.
Design/methodology/approach
This exploratory qualitative study was conducted by means of interviewing road carriers from the container transportation industry.
Findings
In a truck-sharing initiative, technical issues (e.g. carrying capacity) arise, some of which involve the container truck and some involving constraints that cannot be controlled, such as driving restrictions, seaport operating hours, and the presence of the large number of container categories pertaining to the industry. Therefore, a significant amount of “structural empty running” may always prevail. It should also be noted that some, seemingly vital, constraints can actually be changed, treated, or modified for better truck-sharing outcomes, such as building a foundation of trust and establishing coordination among road carriers.
Practical implications
A probable solution to the problem of increasing hinterland transport capacity is to make appropriate use of the huge number of idle truck slots that exist; this could be achieved by encouraging the acceptance of the challenges of truck-sharing realistically and suggesting an approach to handling them.
Originality/value
To broaden its appeal, truck-sharing initiatives must be able to overcome challenges by combining theoretical insight with an understanding of the practical aspects of such an endeavor. This original research fosters knowledge that is unique and which also has real-life applications in maritime logistics studies and supply chain literature for both port authorities and container road carriers.

Abstract
Purpose
A Workplace Parking Levy (WPL) scheme represents a major transport demand management intervention which raises a levy on private non-domestic off street parking provided by employers to employees, regular business visitors and students. It therefore increases the average cost of commuting by car and stimulates a contraction in the supply of workplace parking places. Under UK legislation the revenue from such a scheme is hypothecated funding for further transport improvements. As such it is potentially an important mixed policy instrument available to transport authorities to tackle traffic congestion and create extra transport capacity by using the additional funding such a scheme provides. At present, in the United Kingdom, only Nottingham City Council has implemented such a scheme and thus an understanding of how that scheme was implemented, how it operates and the outcomes after a full year of operation are of importance to transport academics and other local authorities considering utilising a similar approach.
Methodology
This chapter presents an overview of the WPL scheme in Nottingham. The legislation, implementation experience, monitoring framework and outcomes for this scheme after the first year of full operation are discussed by drawing on current literature, documentary evidence and monitoring data.
Findings
The Nottingham WPL scheme was fully implemented in April 2012. The gap between the provisions of the underpinning legislation and the functioning scheme has necessitated the formulation of policy in line with the spirit of the legislation. Acceptance by the business community and the public were further barriers to implementation which were mitigated by a consultation process and a Public Examination. However acceptance remains a concern until the scheme has been shown to meet its key objective of reducing congestion. To date there is no evidence that the scheme has had a negative impact on business investment and, while there is as yet no evidence traffic congestion has reduced, it is still early for such impacts to be identified especially as the majority of the associated public transport improvements are yet to be implemented. However the WPL has already raised £7 million in net revenue in its first year of operation which is hypothecated for public transport improvements which may help encourage inward investment and reduce car travel.
Practical implications
At present the Nottingham WPL scheme has only been operational for a short time and a limitation to the research presented here is that the major public transport improvements part funded by revenue hypothecated from the WPL are not yet in place. It will be necessary to wait at least a further 3 years before more definite conclusions as to the success of the WPL package can be drawn.
Originality/value of the chapter
As the first of its kind in the United Kingdom or indeed in Europe, the WPL scheme in Nottingham provides a unique contribution to the literature, comparing and contrasting implementation and outcomes with those in Australia and Canada. Geographical and cultural differences between the United Kingdom and these countries mean that conclusions drawn concerning existing schemes in other continents are not necessarily transferable to the United Kingdom. This chapter provides evidence in a UK framework to assess if the approach could be suitably applied more widely.

Abstract
From the tourist point of view the chief purpose of travel is that the destination should be different from home and better in some ways. In Jamaica, the environment, both natural and man‐made, remains the backbone of the tourism product. The maintenance and protection of the environment is therefore crucial to the continuing growth of the island's tourist industry.
