Optimal Design of Bike Lane Facilities in an Urban Network

چکیده
Cycling can improve the health of riders, reduce carbon emissions from travelling, relieve congestion in the transport network, and save health and social care costs. According to the Australian National Cycling Strategy 2011-2016, the goal is to double the number of cyclists in the next 5 years. Bike lanes play an important role in promoting bike travel in a safe and protected environment. Currently there has been no methodology developed in the past to design an integrated bike lane system from the network point of view. This paper presents a Mixed Integer Programming (MIP) formulation to optimize the benefits associated with the development of a bike lane network in urban areas. The formulation balances the benefits to cyclists and potential dis-benefits to drivers. A route choice model is adapted for cyclists and a traffic assignment model is employed to model driver behaviour. The outcome is an optimal placement of bike lanes that can assist in designing bike lane networks. An application of the methodology is demonstrated using an example network.

Efficient and clean urban mobility is a key factor in quality of life and sustainability of towns and cities. Traditionally, cities have focused on cars and other fuel-based vehicles as transport means. However, several problems are directly linked to massive car use, particularly in terms of air pollution and traffic congestion. Several works reckon that vehicle emissions produce over 90% of a...

This study evaluates individual preferences for five different cycling environments by trading off a better facility with a higher travel time against a less attractive facility at a lower travel time. The tradeoff of travel time to amenities of a particular facility informs our understanding of the value attached to different attributes such as bike-lanes, off-road trails, or side-street parki...

The perception of colour and its subjective effects are key issues to designing safe and enjoyable bike lanes. This paper addresses the relationship between the colours of bike lane interventions-in particular pavement painting and intersection design-and the subjective evaluation of liking, visual saliency, and perceived safety related to such an intervention. Utilising images of three real bi...
