Abstract: Street vendors use sidewalks to display goods and services. The reduction of sidewalk space by sidewalk vending activity forces pedestrians to take evasive action by changing walking speed and/or direction. Based on previous qualitative studies pedestrian evasive movements are related to pedestrian level of service and sharing carriageways. The aim of this paper was to investigate the effect of typical sidewalk vendor on average pedestrian walking speed and lateral position. The study used a field observation followed by a controlled walking experiment to study pedestrian behavior in the presence of typical sidewalk vendor. A univariate analysis of variance (ANOVA) of pedestrian trajectories, extracted from a walking experiment, showed that the average pedestrian lateral position and walking speed were significantly affected by the presence of a sidewalk vendor, pedestrian flow rate and the interaction effect of the two (p read more... read less...

Abstract: Motorcycles is a dominant transport model in many Asian Cities. Similar is the case with Karachi, where motorcycles constitutes approximately 52% of the overall passenger transport. Although a motorcycle provides temporary relief in terms of low fuel price, ownership of a vehicle and on top of all an easy commuting option to its owners, it has adversely affected the whole (transportation) system including its users. This paper analyzes various governmental policies that led to the enormous increase in motorcycles and its effects on street crime, Traffic Violation and Traffic Congestion. User attitudes towards opting motorcycles, public transport and environment are also discussed in this paper whill shall be helpful in conducting future studies in this regard. read more... read less...

Abstract: Accident Reporting Form (ARF) is the basic building block of an Accident Database. Incorrect and incomplete forms result into the formation of erroneous database which contains partial or no essential information required for the statistical analysis of accident data. Policies made on the basis of the results of such databases will have little or no effect on the improvement of safety of roadway facilities. In most countries filling of the ARF is the responsibility of Police/Investigating officers. Due to lack of interest, all the details are not recorded by them. Thus, it is very important to investigate the type of attributes and their respective items filled most. The objective of this study is to evaluate the attributes given most importance by the person in charge of filling the ARF and the items most neglected. The probable reasons for the complete/incomplete recording of the details of certain items were also examined. For this study a total of 642 forms were obtained from the Malaysian Institute of Road Safety Research (MIROS) for evaluation. Each form contained 91 attributes, as per number given in the accident reporting form known as POL 27. The items were divided with respect to driver, passenger, vehicle, pedestrian, location, road environment, road information and additional information. The fill-ability for each item was estimated in terms of percent filled. The items were evaluated in terms of least and most filled and the probable reason for the complete/incomplete filling of each item was then investigated. It was found that items related to location were most neglected. The second most incomplete items were associated with the vehicle and the driver. While the attributes related to the road and the environment were found to be the most filled. The probable reason for lack of fill-ability of location related items was their placement in inappropriate sections. The important finding of this study is the high number of items in the POL 27 which makes it difficult for the officer to fill the form completely and is the major cause of reduced fill-ability. read more... read less...

Abstract: This paper presents descriptive analyses to investigate the transferability of FEATHERS, an activity-based travel demand model developed for Flanders (Belgium), to a region in a developed country to Ho Chi Minh City (Vietnam), a metropolitan area of a developing country, using personal and household travel survey data. The transferability was tested by using indicators which represent individuals’ activity and travel behaviors. The results confirm the transferability of the FEATHERS modelling structure to Ho Chi Minh City (HCMC), yet all sub-models require recalibration due to the different cultural settings between the two study areas. The differences in transport mode options, land use patterns and individuals’ location choice preferences make transport mode and location choice the least transferable models. read more... read less...
