Managing sidewalk pavement maintenance: A case study to increase pedestrian safety

Abstract

Comfort is a major requirement in planning pedestrian facilities. Pedestrians walk where they feel comfortable and when they do not feel at ease, they walk elsewhere. A typical example is that filthy, distressed, or too narrow sidewalks induce pedestrians to walk on carriageways. This behaviour jeopardizes road safety and highly dangerous to most users, leave them vulnerable. Unsuitable pavements can be the result of irregular maintenance\ud operations to restore evenness after shock damage, weather phenomena, installation of equipment (e.g., posts, fences, urban furniture) with a reduction of walkable surface, or substandard repair work on pavements and patches due to emergency operations. These problems can be solved with an appropriate maintenance management system, which optimizes financial resources to make smart decisions about how to intervene with an adequate and lasting maintenance operation. This paper defines an evaluation index for sidewalk conditions as a part of an efficient set-up of a Sidewalk Management System, which is similar to the better known Road Management System. The study relies on surveys, as well as the classification and analysis of sidewalk distresses. The authors adapted an index already standardized by ASTM for roads and airports: the Pavement Condition Index (PCI). PCI has been modified to consider the specific types on the sidewalks studied within this paper. To validate the method, a case study of a residential district in Rome, Italy, was carried out. The chosen area lacks regular maintenance and has therefore resulted in a network of unsafe sidewalks. Frequent detour routes were surveyed and related to the level of distresses within a general assessment of safety. This study concentrates on sidewalks with flexible pavements cause this type of pavement is the only one adopted in the survey areas and, in general, throughout Italy

Sustainable Road Maintenance Planning in Developing Countries Based on Pavement Management Systems: Case Study in Baja California, México

“…It is important to mention that this research applies the concept of pavement management of roads, highways and major roads. Nevertheless, few studies have applied pavement management activities on urban areas [16,17] and pavement sidewalks [18], proving its reliability in these areas.…”

Design of the First Italian Roundabout with Jointed Plain Concrete Pavement

“…In the first case they can be located at intersections with high traffic volumes; in the second case they replace quiet residential junctions, in the form of miniroundabouts, to make intersections safer for pedestrians, and vulnerable users in general [2][3][4]. The roundabouts can as well cut down vehicular emissions and fuel consumption by reducing the vehicle idle time at intersections and thereby creating a positive impact on the environment [5][6][7].…”

Sustainable Pavement Management System in Urban Areas Considering the Vehicle Operating Costs

“…In particular, municipalities have to face the maintenance of a huge number of roads with The applications of PMS to urban areas are few in the world. Some efforts have been performed to calculate the pavement condition of sidewalks [14] adapting the widely used Pavement Condition Index elaborated by Shahin [2] for roads and airports. In Utah (USA), a transportation infrastructure maintenance management system for a small urban city was developed [15] to assist a municipality in allocating its resources to transport maintenance.…”
