Priority Management for Urban Arterials. Transferability of Techniques: York/Selby Road.

This paper describes the background and methodology employed in research funded by EPSRC to assess the effect of individual traffic control measures, both in isolation and in combination upon urban arterials. The aim of the project was to test the transferability of the techniques developed in a DRIVE II project, PRIMAVERA, to a range of different types of urban corridor. Measures can be classed into three broad categories: Congestion Management, Public Transport Priority and Traffic Calming. The scope of these measures is wide, some operating at a junction level whilst others affect the whole network. Measures from these areas are applied to a sophisticated microsimulation model of four urban arterial corridors: three in Leeds and one in Leicester. The effects of the application of individual and integrated measures are assessed in terms of their efficiency, environmental and safety impacts using a form of Multi-Criteria Analysis. Travel time and other monetary costs are also taken into consideration. This paper reports the results for the A64 York and A63 Selby Road which are the main arterial routes to the east of Leeds.

Priority Management for Urban Arterials. Transferability of Techniques: Humberstone/Uppingham Road.

This paper describes the background and methodology employed in research funded by EPSRC to assess the effect of individual traffic control measures, both in isolation and in combination upon urban arterials. The aim of the project was to test the transferability of the techniques developed in a DRIVE II project, PRIMAVERA, to a range of different types of urban corridor. The techniques concerned can be classed into three broad categories: Congestion Management, Public Transport Priority and Traffic Calming. The scope of these measures is wide, some operating at a junction level whilst others concentrate on the efficient use of road space. Measures from these areas are applied to a sophisticated microsimulation model of four urban arterial corridors: three in Leeds and one in Leicester. The effects of the application of individual and integrated measures are assessed in terms of their efficiency, environmental and safety impacts using a form of Multi-Criteria Analysis. Travel time and other monetary costs are also taken into consideration. This paper reports the results for the A47 Humberstone and Uppingham Roads which form the main arterial route to the east of Leicester

Priority Management for Urban Arterials. Transferability of Techniques: Methodology and Summary.

This paper describes the background and methodology employed in research funded by EPSRC to assess the effect of individual traffic control measures on urban arterials, both in isolation and in combination. The aim of the project was to test the transferability of the techniques developed in a DRIVE II project, PRIMAVERA, to a range of different types of urban corridor. Measures have been classed into three broad categories: Congestion Management, Public Transport Priority and Traffic Calming. The scope of these measures is wide, some operating at a junction level whilst others have an impact over a whole corridor. Measures from these categories are applied in a sophisticated microsimulation model of a series of hypothetical networks and four urban arterial corridors: three in Leeds and one in Leicester. The effects of the application of individual and integrated measures are assessed in terms of their efficiency, environmental and safety impacts using a form of Multi-Criteria Analysis. Travel time and other monetary costs are also taken into consideration. Whilst these results are of interest to local planners in the operation of each of the arterial corridors studied, a wider insight into the operation of urban arterials can be drawn from this study leading to more efficient control of the available road space

Priority Management for Urban Arterials. Transferability of Techniques: Otley/Kirkstall Road

This paper describes the background and methodology employed in research funded by EPSRC to assess the effect of individual traffic control measures, both in isolation and in combination upon urban arterials. The aim of the project was to test the transferability of the techniques developed in a DRIVE II project, PRIMAVERA, to a range of different types of urban corridor. Measures can be classed into three broad categories: Congestion Management, Public Transport Priority and Traffic Calming. The scope of these measures is wide, some operating at a junction level whilst others affect the whole network.

The effects of the application of individual and integrated measures are assessed in terms of their efficiency, environmental and safety impacts using a form of Multi-Criteria Analysis. Travel time and other monetary costs are also taken into consideration. This paper describes the study of two neighbouring arterials to the west of Leeds, the Otley and Kirkstall Roads. These arterials have been considered together since they are geographically close to each other. The Otley Road is the main arterial to the north west of Leeds City Centre, linking the Outer Ring Road to the Centre and is approximately 5km in length. The Kirkstall Road is to the south of the Otley Road, running west to east. The section of Kirkstall Road chosen for inclusion in this combined corridor is 3.5 km in length. The land use surrounding each corridor is primarily residential although near the city centre on the Kirkstall Road there are light industrial units. A popular district shopping centre exists halfway along the Otley Road

Model-based Transportation Performance: A Comparative Framework and Literature Synthesis, Research Report 11-09

In an era of limited resources and a proliferation of data, there is increasing pressure to conduct careful evaluations of the economic, environmental, and equity effects of investments and policies that influence transportation and land-use systems. This report compares performance measures recommended to achieve desired goals and reviews the literature to determine the degree to which these measures have been implemented and what they indicate about the relative effectiveness of land-use, transit, and automobile pricing policies. Despite the variation in methods and performance measures implemented in the studies reviewed for this report, the synthesis of study results suggests the direction and relative magnitude of change resulting from different types of policies, as well as potential biases introduced by omitting the representation of the land-use and transportation interaction. Overall, the performance measures indicate that carefully designed transit, land-use, and automobile pricing policies may improve travel, economic, environmental, and equity conditions for communities. However, transit and peak-period automobile pricing policies can, in some situations, lead to negative performance outcomes across some or all measures, as illustrated in studies that explicitly represent the land-use and transportation interaction

The multi modal study of transport investment plans.

In 1998 the UK Department for Transport commissioned a programme of 22 studies to examine the most acute congestion problems on the English road network. The studies promised a new approach to reducing road congestion by examining the contribution that all modes of transport could make to solve these problems. The studies have provided the most convincing evidence to date that road building alone will not be able to solve congestion and pollution problems. Extra road infrastructure will, in most cases, buy a few years’ respite from congestion on the inter-urban road network. The studies have proposed substantial packages of road and public transport improvements, combined with demand management and traffic restraint measures, to tackle the problems. The evidence suggests that some form of road-user charging will be required in many areas to ensure that the efficiency benefits gained from the extra road capacity will not simply be eroded by traffic growth as has been seen to date on routes such as the M25. The outcomes of the studies have prompted the Government to undertake a review of the potential for a national road-user charging system. The multimodal studies have undoubtedly brought about a more balanced and integrated approach to transport planning. There have been quite significant changes to the roads schemes that were initially remitted to the studies and evidence to suggest that significant environmental concerns are now playing a much stronger role in decisions taken by the Department for Transport. The challenge now is to ensure that all of the major parts of the integrated strategies proposed are delivered. A failure to do so will not only reduce the benefits the proposals offer but will also devalue the multi-modal approach taken to the studies

Sharing Mobility Data for Planning and Policy Research

A California Public Utilities Commission (CPUC) rulemaking and possible legislative action in 2020 could affect data sharing requirements, with implications for shared mobility providers. The purpose of this brief is to inform this regulatory and legislative decision-making. We solicited policy and planning questions and data needs for shared mobility from within the University of California Institute of Transportation Studies research network. We defined shared mobility as including shared mobility devices, such as e-bikes and e-scooters, and transportation network companies (TNCs). We evaluated whether data shared in accordance with each of six mobility data specifications could be used to support analyses that would answer these questions. We then defined three approaches to data sharing and analysis to address these and other questions, presenting the advantages and disadvantages of each. This brief does not address the full breadth of the questions raised in the CPUC rulemaking nor does it introduce the complexities of this topic. Beyond the scope of this brief are issues of user privacy, the legal authority for sharing data, and contractual or requirements for each possible model of data sharing and analysis
