The speed-density relationship was found to be nonlinear for both groups. Kotkar et al. [8] carried out study at four locations in north India. For up direction free flow speed varied between 82.21 m/min to 88.93 m/min whereas for down direction it varied between 80.80 m/min to 86.38 m/min. The minimum and maximum jam density was found to be 2.59 ped/m2 and 4.17 ped/m2 respectively. Space required for pedestrian movement was 0.21 to 0.41 m2/ped while at free flow space requirement was 0.50 to 0.80 m2/ped. It was concluded from the results that with the increase in frictions faced by a pedestrian, contrary to the normal belief, the pedestrian speed also increases. Nazir et al. [9] studied the pedestrian flow characteristics on the walkways at three locations in Khulna Metropolitan City, Bangladesh. This study showed that the characteristics of the location have effect on the pedestrian flow characteristics. The free-flow speeds of this study were found lower than the Asian and Western countries. The observed free-flow speed and densities were found proportional to each other. It was found that the increase in road friction also increased the jam density Rastogi et al. [10] did a major study on pedestrians in Indian conditions. For the study nineteen locations in five cities of India with different pedestrian facilities and situations were selected. Based on their widths these facilities were classified as on their width as sidewalk, wide-sidewalk and precincts. Speed-density, flow-density and flowspace (flow-area module) were found to be best in exponential relationship while flow-speed equation followed logarithmic relationship. Pedestrian behaviour was found to similar upto a width of 9.0 meter, beyond this behaviour changes drastically. The flow characteristics were found different from those observed in USA, UK, China and South-East Asia indicating a cultural effect. Most of the studies are based on the plain cities with dedicated pedestrian facilities. Not much work has been done in the hilly regions where walking is tougher as compared to plain regions and absence of dedicated facilities makes it tougher. So more work is required to understand the various aspects of pedestrian behaviour in hilly regions. 3. Study Area Dharamshala has been chosen as the study area for the present work. Dharamshala is situated in the upper reaches of the Kangra Valley in Kangra district of Himachal Pradesh state in India. With average elevation of 1457 m, the city is famous among tourist from India and various other countries. Pedestrians in Dharamshala city are of different ethnicities such as local residents, Tibetans in exile, foreign and Indian tourists which makes it more preferable for study. Details of the selected sites are given in Table 1. Table 1: Details of the Selected Locations Location ID Location Carriageway Width (m) Gradient (%) BSD Bus Stand, Dharamshala 7 3 MRD Meera Restaurant, Dharamshala 7.5 4 AHD Asian Hotel, Dharamshala 3 9 Exclusive Facilities No 4. Data Collection To have an extensive study of number of pedestrians and their walking behavior, videography survey was performed. A static video camera was used to record the situation at the selected observation sites of known length and pedestrians were video graphed. This process was repeated for all of the sites. These videos were later analyzed in the laboratory. Site features such as carriageway width and footpath width (if present) were measured using measurement tape. The gradient of the carriageway was calculated with the help of Global Positioning System (GPS) device. Ankit Gupta et al. / Transportation Research Procedia 25 (2017) 4720–4732 4723 5. Data Analysis Pedestrians were video graphed over the measured test length of 4 meter which was marked on the carriageway by two visual lines across the carriageway. From the recordings, the walking speeds of pedestrians were manually extracted from the recorded videos. The accuracy of time for the speed measurement was about 0.1 sec. The time taken by a pedestrian to traverse the test length was measured from the recording and by dividing the length of marked stretch by time taken by a pedestrian gave us the walking speed of that particular pedestrian. Figure 2 shows the screenshot of the captured videos. The two yellow markings visible in pictures are 4 meter apart which were laid down during the site surveys. Time taken by the pedestrians to cross these lines was calculated which ultimately gave the walking speed of the pedestrians. Density of the pedestrians was calculated by counting the number of pedestrians crossing the yellow lines during per minute interval in each direction. a) BSD b) MRD c) AHD Figure 2: Site Locations in Dharamshala with 4 m Markings To extensively analyze the effect of gradient on pedestrian flow characteristics the pedestrians were categorized on the basis of their age and gender. Age and gender of the pedestrians were determined based on the visual inspection of the videos. Based on these categorization pedestrians walking speed of one type were compared with the pedestrians of the same type traveling in the other direction of travel. Similarly, the effect of gradient was checked on pedestrians who were carrying baggage (luggage) along with them and compared to pedestrians who were not carrying baggage [6]. Pedestrians’ categorization based upon several factors is given below in Table 2. Table 2: Pedestrians’ Categorization Factor Categorization Young (0 to 15 years) Age Young adults (16 to 25 years) Elder adults (26 to 50 years) Elders (51 years & above) Gender Baggage Male Female With baggage Without baggage For the walking speed of pedestrians, maximum walking speed, minimum walking speed, average walking speed and standard deviation of the walking speed was also calculated for both uphill and downhill direction. Subsequently all aforementioned speeds were calculated irrespective of the direction of travel. After calculating the walking speed of pedestrians, density of pedestrians crossing the 4 m stretch was calculated for every one minute interval of the 1 hour video. By inversing the density of pedestrians the space (area module) of the pedestrians was calculated. Ankit Gupta et al. / Transportation Research Procedia 25 (2017) 4720–4732 4724 Walking speed and density of pedestrians together gave flow of the pedestrians. Pedestrian LOS of the selected research locations was derived from the standards laid down by IRC 103: 2012 [5]. 6. Result and Discussion For the analysis of pedestrian behavior and characteristics, recorded videos were extracted and different pedestrian behavior parameters i.e. speed, flow, density etc. were calculated. Different results derived from extracted data and their discussion is given as follows: 6.1 Pedestrian sample size characteristics From the visual analysis of the recorded video it was found out that pedestrian sample is male dominant consisting of 68% males and 32% females. Visual analysis also showed that 84% of the pedestrians were adults (age 26-50 years) followed by 9% elders (age more than 51 years), 4% young pedestrians and 3% young adult (age 16-25 years) pedestrians. Nearly half the number of pedestrians carried baggage with them where baggage varied from small handbags to big suitcases and travel bags. Pedestrian sample size distribution in Dharamshala city at selected sites is represented in Table 3. Table 3: Pedestrian Sample Size Distribution Male Female 0-15 years 16-25 years 26-50 years 51 years & Above With Baggage Without Baggage Sample size 1837 856 103 86 2253 251 1291 1402 Percentage 68% 32% 4% 3% 84% 9% 48% 52% 6.2 Walking speed of pedestrians Pedestrians walking speeds were obtained from the video analysis of the selected locations. The results from video analysis of all the three locations for uphill direction are presented in Table 4.

In the total 1418 pedestrians males with a mean speed of 61.22 m/min were faster as compared to females with mean speed of 54.82 m/min. Analysis showed that the young adult pedestrians (16 to 25 years) were faster than other three categories with a mean walking speed of 62.78 m/min. while elders (51 years and above) were the slowest with a mean walking speed of 49.88 m/min. Pedestrians with baggage walked slowly as compared to pedestrian without baggage with a speed difference of 3.15 mm/min (5.48%). Downhill pedestrian speed analysis data is given in Table 5. Downhill pedestrians showed a similar trend as uphill pedestrians. There were total of 1275 pedestrians in the downhill direction. Male pedestrians with a mean speed of 71.74 m/min. were faster than female pedestrians with a mean speed of 65.27 m/min by a difference of 6.47 Ankit Gupta et al. / Transportation Research Procedia 25 (2017) 4720–4732 4725 m/min and percentage difference of 9.92%. As seen in uphill direction young adult pedestrians (16-25 years) had the fastest mean walking speed of 74.55 m/min while elder pedestrians (51 years and above) were the lowest with the mean walking speed of 56.92 m/min. Pedestrians with no baggage with mean walking speed of 71.85 m/min, were faster than the pedestrians with baggage who had a mean walking speed of 67.44 m/min and the difference was 4.41 m/min or 6.54%.

After comparison, it is quite clear that the male passenger has the higher mean speed in both upside and downside direction at all three locations. Male pedestrians had highest mean walking speed of 62.92 m/min in the uphill direction and highest mean walking speed of 72.85 m/min in the downhill direction. At all the location (uphill and downhill) except BSD uphill, a similar behavior was seen. At all these location both uphill and downhill direction, young adult pedestrian (16-25 years) had highest speed and elders (51 years and above) had lower speed while at BSD uphill side adult pedestrians (26-50 years) were fastest and uphill young pedestrians (0-15 years) were slowest. Pedestrians carrying baggage were slower than those pedestrians without any baggage on the both directions of pedestrians’ movement. The maximum mean walking speed on pedestrians with baggage in the uphill direction was 60.58 m/min at MRD and 68.33 m/min at AHD in the downhill direction. While the maximum mean walking speed of pedestrians without baggage was 61.63 m/min at MRD in the uphill direction and 74.58 m/min at BSD in the downhill direction. For uphill direction MRD showed higher speed for all the categories as compared to other two locations while for downhill direction no specific trend was observed. Table 9 represents the mean uphill and downhill speeds at all three locations one at a time and then all together. Table 9: Comparison of Uphill and Downhill Speeds at All Three Locations Location BSD Gradient (%) Mean Walking Speed (m/min) Difference in Speeds (%) MRD AHD All Three Locations 3 4 9 - Uphill 59.53 61.13 55.91 59.14 Downhill 73.14 67.65 70.78 69.73 22.86 10.67 26.60 17.90 Mean walking speed of uphill and downhill direction for Dharamshala city was found to be 59.14 m/min and 69.73 m/min respectively with a difference of 17.90%. Common expectation about walking in hilly region is that increasing gradient slows down the speed but no such trend is observed from the analysis of the data. As shown in Table 9, mean walking speed at MRD in uphill direction is greater than that of BSD despite the increase in gradient from 3 to 4%. In the downhill direction mean walking speed at BSD is greater than both the other directions despite lower gradient. Many factors can contribute to such behavior. One such factor can be situation of Inter State Bus Terminal (ISBT) at the downhill direction of BSD. Pedestrians might be in a hurry of boarding their respective buses to their destinations which can make them walk faster in case they might miss their bus. Also, Dharamshala city is famous among local and foreign tourists which could affect the pedestrians’ walking speed of the city. Mean walking speeds of pedestrians irrespective of age, gender and baggage, examined in this study are combined all together and detailed in Table 10. © 2017 The Authors. Published by Elsevier B.V.

The fastest uphill walking speed was 96 m/min and 120 m/min in the downhill direction. Whereas the slowest walking speed in uphill and downhill direction was 25.36 m/min and 29.41 m/min respectively. The standard deviation of walking speeds from the mean was 11.88 in the uphill and 12.23 in the downhill direction. Whereas, the mean uphill walking speed of pedestrians was 59.14 m/min. and it was slower than pedestrians mean walking speed on the downhill side which was 69.73 m/min by a margin of 10.59 m/min. The percentage difference between mean uphill and downhill walking speed was 17.90%. When we neglect the gradient of the carriageways, then the mean walking speed of pedestrians was 64.16 m/min with standard deviation of 13. 6.3 Pedestrian flow characteristics relationships The speed-density relationship for all locations was found to be linear and flow-density, speed-flow and flowarea module relationships for all locations were found to be quadratic.

Comparison of Pedestrian Flow Characteristics Relations The developed pedestrian flow characteristics relations for three locations under mixed flow conditions provides an insight into effect of gradient on pedestrian flow characteristics. Speed-density relationships for each uphill and downhill direction is compared with best fit speed-density relations of research done in plain areas (Kotkar et al., 2010) [8] and researches done on sidewalks in Singapore (Tanaboriboon et al., 1986) [11], United States (Fruin, 1971) [12] and Britain (Older, 1964) [13]. The developed pedestrian flow characteristics are compared in Table 14.

For downhill direction, the walking speed of pedestrians on sidewalks is greater than walking speed of pedestrians on carriageways.

Conclusion and Future Scope of Work Present study concludes the following points: The study shows that the gradient affects the walking speed of pedestrians as the uphill speed is lesser than downhill speed at all three locations for every category. However, this difference depends upon the age, gender and baggage handling conditions of pedestrians. • The study indicates that the walking speed of pedestrians is also affected by human intentions besides topography of the sidewalk as in case of locations near bus stand. • The pedestrian flow characteristics of the selected locations varied significantly thus not showing any definitive trend with changing gradient. • The speed-density relationship for selected city results in poor walking speed of pedestrians in hilly cities when compared with other researches. • The effect of traffic on pedestrian characteristics is evident. The pedestrians of hilly cities walk with traffic under the influence of gradient and thus have to face more difficulties in travel than pedestrians walking on the sidewalks or other exclusive pedestrian facilities. • The pedestrian LOS for in both the directions of travel on the basis of the guidelines laid by the Indian Road Congress code IRC 103:2012 comes out as ‘A’, despite the fact that the pedestrians were walking on the carriageway instead of sidewalks. • Based on the study it is recommended that in case there is no sidewalk on either side of the carriageway and there is hill or buildings on the one side of the carriageway and other side has no buildings then an overhanging sidewalk should be provided. If there is no land available on either side of the road then pedestrian flyover can be provided. At places with high gradients stairs can be provided to facilitate pedestrians. Present work on pedestrian flow characteristics covers some of the aspects of pedestrian flow behaviour, environment and traffic. There is still a great need of extensive studies focused on aspects already considered earlier and which are absent in these studies. Some of the aspects and methodology which should be considered while studying pedestrian flow characteristics are weighted count of pedestrians, flow characteristics of disabled pedestrians, effect of other surrounding and environmental factors such as presence of obstruction, presence of railing, trees, street lights etc. Present study fails to develop any relationship between gradient and other pedestrian walking parameters so more work should be done with more locations of different gradients to establish relation between change in gradients and uphill and downhill speeds on carriageways and sidewalks and based on that limiting gradient for pedestrian facilities should be recommended. • References: [1].
